Title: My first Synergy... the N7 build!
Post by: rcnut on February 03, 2015, 01:53:41 PM

 Hi everyone!

Today I receive my Synergy N7 heli, so I'm new to the family! ;D   I've flown a lot of other helis in the past, but this is my first Synergy heli that I will fly and OWN! So I'm looking forward to this experience! I can't wait to see what's in the box...and start building...

You are going to enjoy the N7 build.  My N7 is my first Synergy Heli and I can tell you the kit is a dream to build.  I received a E5 from Santa this past year and will be building it when I return home from Arizona in the spring.  Looking forward to that build.

Welcome to the Synergy family.

Thanks guys!:D I just arrived home and my new heli was at the door waiting for me!!! I am so stoked. Last night I began removing everything from my Team Heliproz Nitro Whiplash (the Red addition). It was a heart felt experience. As I was building my Whippy, I never thought I would be pulling the equipment out of it. :(

So the Synergy will be my special nitro heli. I can't wait to get started on it!!! I took the time to write this while the printer is printing the instruction manual. Tools at the ready, workbench cleared off, I'm good to go!

I'll drop in some pic's shortly. The sad part of all this………it's SNOWING again! Aaarrrggg! And now the printer is out of ink!!! Aaaahhh! I have refills! On with the build…

Ok, so I was building my N7 and found the cooling fan has a broken fin. Not sure what to do about it. Possibly glue it back together, or just order another fan. And, how do I upload pic's here?

Hi rcnut,

Sorry to see the fan is damaged in your kit, i would'nt recommend repairing the fan as this could possibly cause balance and vibration issues.

I would recommend that you contact your dealer or contact Matt and Amy directly and they will take care of this for you. :)

Hope this helps, let us know how you go.

Thanks Ross!

I placed an order for a replacement fan...$6! That was cheap, and I ordered some other things. All in all its good. I have a club meeting tonight, but I'm thinking of not going so I can spend some serious time building my new heli. I do need to clean the greese out of the clutch one way as I plan to test flight before winter is over! We've had some very nice 35 degree days with 0-6 mph winds and clear skies!

Post by: rcnut on February 06, 2015, 07:36:46 AM

While I'm waiting for the replacement fan to show up, I continued building all the subassemblies. Right now, I have a bunch of parts and a stack of carbon fiber just sitting on my work bench...it doesn't look like anything, anything resembling a heli...LoL! Tonight...it will build into a heli! I'm in the process of sanding the edges on the carbon fiber. And I have all day tomorrow (Saturday) to see how far I will get!

I found this canopy for my N7 (Synergy N7-3 on RR site). Its from Sick-Canopy. I really like the color scheme!



Arrgg! Still trying to figure out how to upload pic's!!!

Good to hear your moving on with the build, you will be surprised at how quickly it comes together once you get going. A good tip for sanding the edges is to get one of those small foam sanding blocks, i use them on all my frames and it just takes a couple of passes with the foam sanding block to clean and smooth the edges.

Tip for adding attachments, if you edit your post or when you are replying to the topic you will see a small box with a + symbol in it, it will also say 'Attachments and other options. If you click the + box it will give you the options to upload pictures from your computer and if you need to upload more than one picture just click the more attachments.

Let us know how you go, and if you have any questions just give us a shout.  :)

Add some pictures as your build progresses too, it's always good to see another N7 come to life!  :)

Cheers,
Ross

Ok, I've selected a couple of pic's to display, let's see if I've figured this out! LoL!

And as Ross Lawton posted;

He was right! Once all the subassemblies were addressed (loctite) and the edges on the carbon fiber were sanded, the body built up rather quickly. It wasn't long and I was installing the servos. I started the edge sanding shortly after work on Friday, and before I knew it, it was late and I was having a difficult time keeping my eye's opened!;D So it was off to bed. I stopped at installing the second cyclic servo as the MKS servos are too tall and hit one another. After texting my buddy Mark, he made mention (as I was thinking of the same thing at the same time) to add some spacers under the mounting tabs. But at the time I was installing them and discovered the problem, I was too tired to think clearly and was thinking of buying different servos to put in. Yep, it was time for bed!

Saturday, after my morning routine, I headed to the hobby room to continue with the build. I found the spacers needed to move the two servos out by 3/16" 'ish, the thickness of the metal servo hold down plates that comes with the kit. Then I received a text from Mark wanting to go out flying!!! I said "What???" Me: "But I'm in the middle of a heli build!" Mark: "Let's go flying!" Me: "ok"… So we headed out.

Once back home, we looked at my progress on the N7. Then we noticed I was missing one boom support! :o! I have two tail control rods, but one boom support. So after church today, I stopped at my local hobby shop and bought a carbon fiber rod that's very close to the same size…enough to get me by.

Out side of that…I've noticed several areas in the build that Matt paid extra attention to. Like the length of the bolts holding the clutch to the fan hub…they are long enough to go into the hub. In the past, I've built a couple of helis that used bolts that are only long enough for 4 threads going into the hub! 4 threads maybe enough to hold it on, but it won't last long. The general rule I've been told is 1 and a 1/2 times the diameter of the bolt, will give enough threads to hold properly. Me…I like to use as many as I can short of bottoming out the hole…but that's just me.

Anyhow, it's time to build some more on my N7! I have some Spartan Vortex programming to do before installing the elevator servo!

Ok…can't post the pic's, file size is too big! Oops!

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on February 10, 2015, 08:44:46 AM

Here are some of my review notes;


My Synergy N7 build…

Ok, so here we are at the beginning of February…and I have a new heli to build! I received my Synergy N7 from Experience RC. There shipping is very fast! I ordered the N7 Thursday night as Experience and Helidirect were the only two shops that had one in stock. I clicked on the “Add to basket” button on Helidirect, and the site crashed! So I ordered the N7 from Experience. Tuesday, it was at my door! I was expecting it like Wednesday/Thursday time frame…

The build begins

I opened the box and pulled everything out to look at. Then it was time to fire up the MacBook Pro to print out the manual. Right in the middle of the print, the printer ran out of ink?!!! Great! No problem, I have a spare cartridge. I finished the print and headed off to start building my N7…finally!

The manual has you start with the fuel tank. It “looks” like an Align tank for one of the Trex 700 V2 helis (I have the Trex 700N heli, just haven’t looked at it to compare). So the tank builds up like any other tank…vent, feed line, clunk, etc.

Next is the landing gear. For the most part, the landing gear is assembled like most except for the tube locks? They are something like a frame spacer, but only one inch long with a threaded hole through the center and a threaded cross hole where the bolt from the landing gear goes into to hold the skid tubes in place. A cool feature, the skid tubes have predrilled holes in them for the skids…no measuring the skid tubes!

Now, to get those tube locks in place. My first thought was to find something I could run the tube lock up front to the first hole and possibly hold in place while I screw the bolt into it. Ah…a threaded rod! I had a 4-40 threaded rod the just worked. The threads were wrong in the tube lock, but who cares, as long as it will hold it in place long enough to get the skid bolt into the tube lock…with some Loctite of course. This worked perfectly for all 4 tube locks.

On to the clutch stack, well nothing special there, just take it apart and Loctite the screws. When I got to mounting the fan hub assembly (hub, fan, and clutch) to the motor, I found one of the fan blades was broken. It must of happened during shipping. The box that all the parts come isn’t packed with anything and the parts bounce around inside. I placed an order with Experience RC for a new fan ($6.00! Not bad) and some other stuff. That showed up in 2 days!!!:)

I continued on with the build skipping the fan shroud as I needed the fan mounted for it. Now you build up the gyro plate, rear frame plate, and radio tray. And while I was playing with some of the carbon fiber, I used this opportunity to sand all the edges on the carbon fiber. I’ve learned to use rubber gloves for this as it leaves a terrible mess on your hands. With the gloves, I just take them off and throw them away along with the carbon mess!

Next is the disassembly of the main gear. All the bolts in this kit are not loctited, you need to remove them all and apply loctite. There are two brass bushings that will need red loctite. The main gear is really big and beefy…I like that! The front tail transmission assembly is a real work of art! It looks very sturdy along with the gears, beefy! Reassemble the boom clamp with loctite. Loctite the tail offset bell crank. I like the offset bell crank design as it places the tail push rod in the center of the boom. Nice touch!

Ok, now the body starts to come together. You start by installing the main bearing blocks, frame spacers, tail and throttle servos, rear frame brace, boom clamps, front tail transmission assembly to the right frame halves, and then install the left side frame halves.

On to the tid-bit stuff…the motor mounts. In the kit you are supplied with motor shims. This is a nice touch. This helps in setting the proper gear-lash and alignment of the clutch stack…kind of like the old Miniature Aircraft days with the X-Cell line of helis.  At this time, I transgressed back to installing the motor fan assembly to my motor, now that I received the replacement fan, but nothing special here, assembly as usual. 

One added note here: Matt really shins here when mounting the clutch to the hub…the screws are long enough to properly engage most of the threads in the fan hub! I’ve built a few “other” helis that gave you much shorter thread length. Only 4 threads would go into the fan hub! An easy recipe for stripping threads and then needing to buy another fan hub! The rule of thumb, as I’ve been taught 1 and a ½ times the diameter of the bolt should be the length going into the threaded hole. So if the bolt is a ½” in diameter, 1-1/2 times will = ¾” long, or ¾” going into the threaded hole.

I fitted the fan shroud to the O.S.105 motor and quickly saw that I needed to remove some material to clear the carb stack and heat sink fins on the head. Now the fan shroud fits! I really wasn’t too keen on how it assembles, using 4 long, but small diameter screws. Yea, I’ve done that before, didn’t really care for it then and still don’t…sorry Matt! It’s a pain in the rear trying to get those screws to line up. I installed the motor, and it was a good fit, no problems, and no rubbing on the fan to the fan shroud.

So now it’s time to square up the frame, this whole frame assembly is done without the frame bolts being fully tighten. What I do is insert the mainshaft through the bearing blocks and then tighten the bolts in a “zig-zag” fashion. One bolt on the left, opposite bolt on the right, etc. This way the main bearing are in perfect alignment to the point that the mainshaft will slide out of the bearing blocks as you rotate the body upside down. There is no drag on the mainshaft or preload on any of the bearings. The mainshaft will side in and out as you turn the body upside down and right side up. After that, I tightened the rest of the bolts on both sides of the frame.

Next I installed the bottom stiffening plate, landing gear, clutch stack, radio tray and gyro plate, protective rubber for the fuel tank and then the fuel tank.  At this time, the three cyclic servos are installed. However, I had a problem with the servos I decided to use...MKS HBL950HV.  The servos are too tall. I had to use spacers under the mounting tabs to gain enough clearance between the two side cyclic servos. I’ll check the alignment of the swashplate linkage, and if needed, I can move the linkage ball to the inside of the servo horn. I think I’ll be fine…haven’t got to this point yet.

Moving on, and while my buddy Mark drools over the main body…leaving “his” finger prints all over it…LoL…I started in with building the tail section. The boom is like any other brand…that has a torque tube. And the tail gearbox is just the same. As I was placing the tail push rod guilds on, I noticed the boom is a straight piece of tubing! No predrilled holes or slots cut out in either end??? And no company/heli name imprinted on the boom! 

The instructions mention “pinning” the tail housing to the boom. Well…I did just that. There are pro’s and con’s to pinning or not pinning the tail or the boom to the body. The two most important reasons I can think of…the tail turning up or down, and the tail box falling off the boom/the boom pulling out of the body. So I pinned it, peace of mind…

According to the manual;

IMPORTANT!
If you wish to use boom pinning feature
you must drill 3mm hole! Follow these steps.
1. Install Tail Box
2. Ensure Tail Box is vertical
3. Mark drill location
4. Remove tail box and torque tube
5. Drill 3mm hole at marked location.


So Mark had noticed that I was missing a boom support and had two tail carbon fiber push rods! Ok, so we found the first part missing from the kit. Sunday I stopped in my local hobby shop after church to find a replacement. It turns out they have one that’s one size smaller than the factory one. Now I could bug Matt about this, and he would send a replacement one to me ASP, but he has better customers to deal with versus waiting on me hand and foot. LoL! 

Also, just because one small part or a cheap (not cheaply made, but cost) isn’t going to deter me from buying this heli. Yes, it would be very nice that all the parts are there, but remember, we are human, we are not perfect, so a part missing is no alarm to dis the company. However, having the owner call you asking for your address so he can send the correct parts…says a lot about the company. I will be talking with Matt in the near future, wanting to get to know the man in person.

Moving on…I mounted the main gear and mainshaft. However, I’m a bit fuzzy on the mainshaft shim thing. According to the manual;

Use the 10mm main shaft shim if you have vertical
movement in the main shaft after assembly. This
is completely normal and within tolerances.

I don’t see/understand where it should go, so, moving on…the head and swashplate are normal…remove and loctite everything and set aside.

I need to start programming the Spartan Vortex VX1n so I can center the elevator servo and mount the carbon fiber control arm to the plastic horn. Once the servo is mounted, there is no way to adjust the servo arm position without removing the servo. The servo horn screw is blocked by the aileron servo, much like the Goblin helis.

And here is where I “went off the beaten path.” So I started the programming. I created a new heli profile in my DX9. I went through most of the radio setup in the Spartan Vortex, enough to center the cyclic servos. I installed the swashplate so I could see the how the balls on the swashplate will line up with the balls on the servo horns. They’re not perfect, as a matter of fact; the center of the swash ball is directly in-line with the servo horn (the center of the carbon fiber horn).

So now it looks as if I need to move all 3 servos out enough to place the servo balls on the back side of the servo horn. So now I’m wondering if I should pick a different servo for this heli… Not just yet!

To be continued…

the picture below should help with the brass shim. mine was not needed during assembly. sometimes as the bearings age a bit, it may need to be installed to remove a tiny amount of up and down play. the note means that the tiny amount of up and down play is perfectly within the tolerances and is ok, but if  you dont like it, you can use that spacer to get it out.

edit - my computer wont allow me to post the pic for some reason.

Hey Mike!

Yea...I saw that as well. I have a much bigger gap than 10mm, above and below that collar. Thought I had did something wrong. I'll look it over again.

I'm not sure what everone is using for pic size, but under the "attachment", it states;

Restrictions: maximum total size 4000KB, maximum individual size 1000KB

So I'll have to reduce all my pic's before uploading. Or use my iPhone...if I can ever figure out taptalk!

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on February 10, 2015, 04:46:44 PM

i may be mistaken, but that collar should be directly on the 3rd bearing block. there shouldnt be a gap at all if any, that shim should take it all up. basically that shim will pick the entire mainshaft, autohub, and head up the thickness of the shim when it is installed in between the bottom bearing block, and the collar.

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on February 12, 2015, 07:56:32 AM

Ok, I was able to spend some time working servo alignment to the swash balls last night. I finally have all 3 cyclic servos setup much better, however, I had to use a fairly thick spacer for the two side servos to achieve this.

I was going to continue with the programming until I grabed my radio only to discover I left the power switch on! For 2 days!!!Arggg:dumb guy!dumb guy!dumb guy! Life happens, and then we move on...

I shut off the radio and placed it on the charger and sat by it, watching to see if anything bad would happen. So far it powers up and the display saya 8.2v... Its been a very, very long time since the last time I did this.

I looked at the gap issue with the mainshaft and 3rd bearing block...yep! There's a gap on both sides of the collar. I'll ty loosening both lower bolts and see if there is and play in them, if so, I'll adjust accordingly!

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on February 13, 2015, 07:25:49 AM

So far my radio seems to be ok! ;D But I will keep an eye on it just in case.

Last night, I worked on all the links. I have them set to what the manual states as a starting point. Then I "Boto-sized" all of them...dang those links are thick!!! Before going back to programming the Spartan Vortex, I worked on the wiring lay-out, and then started in on the rpm sensor.

I'm not that far from finishing my N7...however, with close to record cold temps for this weekend...no madain flight this weekend...possibly next weekend! That gives me plenty of time to double check everything!

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on February 15, 2015, 07:10:57 AM

Ok, I have all the horns on and the links installed.

I did some more VX1n programming, setting up the swashplate and main blades…including mounting the rotor head.

I have the governor sensor set and installed, but haven't programmed it just yet.

Wires are routed with one of two satellites. I need to find another place to install the second sat.

I glued the metal ends on the carbon rod for the rudder servo…and glued one end of the boom supports. I'll glue the other end tonight.

Setup my battery on the front tray, a 5000mAh 7.4 LiPo, its a leftover from a 6 cell pack that went bad shortly after buying the pack. Cell #3 went totally dead, 0.0V, after the first charge. So I stripped it down into smaller packs.

Things left to do:

Setup the linkage for the throttle
Mount the tail section and setup the linkages for the tail
Finish programming the VX1n
And finally, mount the canopy

Oh yea, test flight!!!

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on February 16, 2015, 07:58:51 AM

My N7 update!...

I have the throttle linkage setup and finished, governor programmed and good to go.

Boom suports are done and ready to mount.

Tail servo to the Tail Offset Bell Crank Assembly done. but need to mount the tail assembly and connect the tail push rod...and finish programming.

Thing left to do...

Find a location for the second satellite (I forgot to mention this before)
Do another full "walk-through" the radio and Spartan Vortex (VX1n)

Mount the canopy

And finally...test flight!!!

There might be a problem with the madien flight this coming Saturday...the weather forcasters has forcasted 5-8 inches of snow Saturday afternoon! Starting around 1:00 pm. At 1:00 pm, the chance is 37%, and at 4:00 pm the chance becomes 64%!

I am also NIU's (Northern ILLinois University) unofficial test pilot. Every year, NASA puts on a competition. Anewly designed airplane that can handle a 40 pound payload. Each year a few students, that have entered their school into this competition, design/engineer a new style aircraft in hopes of achieving first place. I'm not sure what first place actually is awarded, but it is big...according to the students.

They have picked this coming Saturday for their test flight! So it would be great if I could test their airplane and the madien my N7! And put a flight (or 2) on Marks G4. That would make for a very exciting day! However, and as everyone knows...This next storm could push into early next week, like Tuesday'ish? It is too early to say what will happen, but...My N7 will be ready for its madien flight...or when ever the weather will allow...

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on February 18, 2015, 07:39:14 AM

Update!

I found a suiteable site for the second satellite. I ordered the O.S. bubbleless clunk and 2 tank grommets. The gromments came in , but no clunk! I trial fitted the canopy to see how much room I have...lots!!! ;D So I'm almost there, mount the canopy, install the muffler, go through the radio and receiver programming, add fuel, and I'm ready for a test flight! Weather providing of course...

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on February 19, 2015, 08:47:18 AM

Almost there!

The bubbleless clunk finally showed up yesterday. I removed the tank (that was interesting!) and was able to pull the ruber grommet out of the tank without damaging it. No rips or tears. I installed the bubbleless clunk without the rubber "O"ring due to it not fitting inside.

Installed the plastic "U" channels and rubber grommets in the canopy, so that is ready. Then I started bundling up the wiring, making it tidy. I drilled a hole in the top of the boom so I can "pin" the boom to the boom clamps.

Not much left now...run through the programming...add the muffler...put the canopy on...charge the LiPo...maiden!

Oh Lord, I hope not!! Then I would have to sell several other helis an buy more Synergy's!!! :o ;D

So on with last nights' build/finish... I started with powering up the Spartan Vortex to run through its' programming and discovered the second satellite wasn't working? For some reason, it wasn't bound, that or I have an issue with the cable going to it. So I started off with binding both satellites, and after several tries, I was finally bound.

At this point, it was time to clamp the tail section in place. I had drilled a hole in the boom for a "pin" (actually a short bolt), so it won't rotate. I've had issue with this many years ago, and I have found several techniques to hold it in place...for a while, but the "pinning" works the best!

Then I added the boom supports, tail push rod with the Teflon sleeves, and loctited all the screws and tightened them. The gear mesh is perfect, and once the "loops were in place and straight, hardly any drag on the tail system. Now back to some more programming.

I went through all the sections concerning the initial setup including the tail section (servo centering, servo direction, end point adjustment, etc.). Everything was perfect from the first time I did this. Then I plugged the "data pod" (an interface for the Vortex controller) into my laptop and used the Spartan Studio (beta) - Vortex Editor M5 for the rest of the programming. This is a really cool program. It allows me full access to see where everything is set to. Plus it has a data logger that I can view to see if the controller is having an issue that I'm not aware of. I was going to do a full write up about this on HF, but I haven't done that just yet.

So now that I was happy with the settings (throttle hold delay setting, Expo, style settings, etc.), it was time to finish this heli! I plumbed the tank, added the muffler, and mounted the canopy. Everything was going great, until I went pull one of the Key Chain Canopy Mounts out. The bottom fell off and that little spring flew out! You know, I haven't been able to find the little bugger! So I used a spare RCbooya Key Chain pin...for now.

So that finishes up with the build. The only thing left is to top off the LiPo and go fly! Oh yea, take some better pictures before it goes in the air.

P.S. Here's a little trivia for you... In the "Frame1" picture, do you see anything wrong with one of the bearing blocks?

You are correct! I didn't find this until I tried to put the collar up against the bearing block. This is what happens when you build upside down! LoL! It's amazing thou, I installed the other 2 blocks correctly? ::)

Is it possible to upload videos here? Or show a link to where it can be found...You Tube, Vimeo, etc.

Title: Re: My first Synergy... the maiden flight!
Post by: rcnut on February 23, 2015, 03:09:49 PM

The Maiden Flight!

Ok guys, grab some popcorn!

Saturday was a mixed bag of where we were going to fly. Mark wanted to stay here and the students want me to go to them, at the NIU campus. As it turned out, I showed up at the NIU campus. I had to wait for the students to finish putting everything together. So… I pulled out my Rave to see if I solved the loud bearing problem…nope! I think it is the main bearing making all the noise. But that wasn’t the only problem I was having with it, the muffler came loose and almost fell off as I was trying to bring it in. I landed with one screw missing and the other hanging on by 4 threads!

Ok, so I put that one back into the truck…still no students… So I pulled out the new and ready (I hope) Synergy N7 out. Now it’s time for a maiden flight!  I filled the fuel tank and no leaks, turned on the radio and then the Spartan VX1n. Red flashing light turned blue and I’m good to go! It took a couple of minutes to get the motor to start, it was cold, heavy overcast with a light breeze, and I had the throttle idle set just under the lowest speed the motor would run.

Once I had the throttle trim set, the motor came to life and began purring like a kitten! So now it’s all or nothing! This maiden flight was done at the NIU campus in back of the engineering building.  I throttled up slowly checking the controls and tail direction. Then I added more throttle and my new heli was airborne!

It had a little shake about the swashplate area, so I think the swash sensitivity is a bit high. The blade tracking is off just a tad, but not a show stopper. I need to increase the tail authority some; it’s a bit slower than what I like. As far as flying around, it is definitely lighter than my other helis.

The flight characteristics are a lot like my Rave, only better, cleaner and crisper! I started off with some left and right pirouettes, and that’s when I noticed I need to increase the yaw per second and decrease the expo…just a little, for my taste.

Then it was time for a few figure “8’s” laps. The synergy handles very nice, tracking as if it is on rails. After the third lap around, I rolled the N7 3 times. WOW!!! The rolls were very aggressive! And that could be why the ailerons are very sensitive (Spartan controller adjustment needed here). Make another turn around and tried some side tic toc’s. It was fast and fun! The collective response is very quick, but not overly quick. Regular noise up tic toc’s were fairly fast, however, I was in idle up 1 which I set for 1850 rpm…using the Spartan governor.

Now for some inverted flying, however, that was short lived as the overcast had some haze mixed, so if I flew too far away (over 75 feet) I would start losing sight of my pretty heli! As it was, the color scheme was beginning to fade, making it hard to see. So I decided to keep it close. Small loop (50 footers), rolls, tic toc’s, forward and back flips, was about as far as I was going to go. Besides, by the time I flown to the ¼ tank of fuel mark, the students were watching and waiting for their plane to make its maiden.

I was going to try an auto, but the twitchiness of the ailerons became too aggressive, so I opted to land normally. Good thing as I hadn’t tried the throttle hold switch…to see where the rpms are set to. I just need some time to adjust some of the settings.

The NIU students…

Everything was set and good to go! Right!!! LoL! There was the preflight check that needed to be performed. I was handed the controls and just the radio was plugged in. I checked all the control surfaces verifying the proper travel directions (no body like to have the ailerons connected backwards, or have the elevator moving the wrong direction…it makes for an interesting flight/crash on takeoff and landing!), and amount of deflection, meaning having enough control surface movement. After a few minor adjustments, it was time to plug the motor in and check the thrust capability. Wow, this motor had enough power to just about takeoff vertically!

Only there is one small wrinkle to the contest; every aircraft has a power limiter. The motor cuts out if you go over a certain power level. Well, it’s now or never time! The students were getting nervous be the second. I knew it would fly, but wasn’t sure how well and what surprises I might find once off the ground. Like too much elevator (up or down), the wrong motor thrust line, something falling in flight, etc.

So as everyone was getting ready and just standing around waiting for someone to say go!...I hit the throttle and off it went. Their plane tracked to the left some and I corrected with some right rudder. A few feet later and it was airborne…WOO HOO! A second new aircraft flies! The experimental plane needed some down elevator trim and some left aileron trim. Once established, I made several laps around the area.

I decided to freak them out and do a low and slow fly-by over their heads. At first they all thought I was coming in for a landing, wrong. I setup for another fly-by as they shouted out to do that again! And I did, this time they got out of the way so I could drop down lower. Did someone say “lower?” He, he, he!!! I was having fun with their plane and remembered the pack will last for 5 minutes, and I was up for 3-4 minutes already! Ok, time to land while it is in one piece.

The students moved out of the way as I made the final turn into the wind. I have the plane lined up with the parking lot driveway; everything looks good, chop the power/throttle, now its glide time! Everything was looking good, but the plane decided to nose up and stalled some, no problem, I goosed the throttle (we heli pilots can that a throttle pump) some to capture  the stall and set the plane back into its decent…touch down!

The students went nuts! They were so happy; one of them said takeoff again! Nope! I’m not doing it. But why not? The plane is in one piece, it flies, and your contest is in less than 2 weeks away! Take the plane back to the lab, and put all your decals on representing your school, and then go out and celebrate. Great idea! So we headed out to a place called “Fatties Pub” I had the “Fatty burger”, it was really good!

The students showed me their next year’s plane…a Tandem Wing. I will need to research this myself, build one and learn to fly one so I can help them with this project.

All in all, it was a good day! Two brand new aircraft were maiden, and both flew successfully.

Post by: rcnut on February 23, 2015, 04:27:42 PM

Hey Mike!

Yes, it is! I'm liking it so far, but I only have one flight on it. I have some programming I need to address, like reduce the cyclic gain  (I think), increase the tail response to my likings. It's ok for now, but needs to be quicker. And last, but not least, tune the motor. The O.S.105 pumped is right at break-in…28 flights on it…ok 29!

I wish the weather would cooperate so I can go out and play with it! And speaking of flying… I see you are having a fun fly, the Bham fun fly next month. What is the weather like that time of the year? And where is a good place to get a room? I'm thinking of coming down this year, but there are a few issues I need to get through right before the fun fly! I might be bringing a friend with, but that depends on his ability to get that time off. I would definitely bring my N7!

Title: Re: My first Synergy... the N7 build!

the weather this time of year can be either too dang hot, or a blizzard! lol literally, in 1993 we had 4' of snow the weekend before out fly in!

it is usually just right though. looks like its getting cold the next few weeks, probably going to warm up and stay that way after that! i think there is a list of hotels on the HF thread, if not on this thread on the Synergy forum too. they are all decently nice, but you will be at the field all day and half the night anyway, right :)

With the weather like it is (super cold with blowing winds, heavy overcast, with threatening snow showers), I' might have to wait until B-Ham to get any flying in!!!

Then again, you may not want me to come down! I just might pull all this nasty cold weather with me...LoL! I'll dress warm just in case...LoL!

Carefull what you wish for...you just might get it! Speaking of getting it...your state has a winter storm warning! At least that is what the radio was saying. Up to a foot of snow! Here in Northern Illinois, we're looking at 3-6 inches from 4:00 PM to morning.

"Oh the weather outside is frightful, but the fire is so delightful, and since we have no place to go...Let it snow! Let it snow! Let it snow!"

Good luck buddy! Enjoy the snow while it lasts...and then get rid of the crap before the fun fly!!!!! LoL!


N7 update:

I dropped the cyclic gain some and decreased the tail expo. Then I checked the blade tracking, it is off by -0.3 degrees. Now its off by +0.1 degree. So my heli is ready for another test flight! This may happen this Saturday (20 degrees with 11 mph winds, and mostly sunny), and or Monday (32 degrees with 8 mph winds, and partly sunny).

N7 Update

Ok, I was able to get 2 more flights in on my N7 yesterday (Saturday). The first flight was fantastic! Boy this heli can fly!!! ;D It feels a lot like my KDS Agile 7.2, light and fast!!!!    I like it! The second flight was a bit uncomfortable. Something, somewhere in the programming (of the Spartan Vortex) is driving me nuts!

Here is what it is doing; normal mode, the heli flys fine. Idle up 1, the heli cocks to the left as if I moved the aileron trim that way. In idle up 2, it cocks to the right? My second Goblin gasser (with the Spartan Vortex) does the same thing only with the elevator. I don't get it. I did manage to get to stop when switching into idle up 1&2. In normal mode, I would climb, making the motor RPM go up to match that of idle 1, and then I would switch into idle 1 and then 2. Then it flys fine! Not sure what to make of all this!

Also, I'm not liking the OS bubbleless clunk, it doesn't seem to pickup the last 1/4 inch of fuel in the tank. It will take a little time to get this heli wrung out. In the meantime, it an awesome flying heli! Did I say it feels a lot like my Agile 7.2, but better?

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on March 02, 2015, 08:12:50 AM

we got 1.5", it was not much, but if was pretty. just about 10 miles north of us they got 11.5"....lol....we just barley missed it.

trash that OS clunk and get a Lynx MOAS clunk. that OS clunk is a paperweight IMO. i also do not like the standard fuel magnet, they do not last long enough, even when running a regulated motor you are replacing them every few months... :-\ the Lynx MOAS clunk has been perfect, it looks just like our Stens clunks in our gassers.....

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on March 04, 2015, 07:25:50 PM

Ok, the weather is soon to change and I will try to figure out what's going on with my N7. I've tried asking for help with the programming on other sites and even personal emails with no replies…so I'll do this myself. First up I'll look into the cyclic gain. Possibly this setting might be too high as when I switch into idle up 1 or 2, the sudden torque causes the FBL controller to compensate with a sub trim adjustment.

Also, I'll look into adjusting the time it takes to change speed from idle 1&2. Now for the collective pitch response…it is a lot faster than what I'l used to. Checking into what others have set the +/- range to, might be the key to the overly sensitivity. Meaning, the more +/- pitch, the more sensitive the pitch becomes…range resolution. Right now, I have a +/-13 degree range. This may be too much…with 715mm blades. So I will drop the pitch range to +/-11 degrees and see how that feels.

So that's the game plan for some much needed warmer weather! And not to mention the B-Ham fun fly coming up!

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on March 05, 2015, 08:33:49 AM

this heli has very fast collective response due to the very light weight. i would also try to run 696mm blades on this heli. every time i transition to this heli, i will have to basically re-learn my collective for tick tocs, and then the stopping on fast hard rainbows, bc the heli will literally shoot off compared to my others....if you dont mind, i will pass your contact info (cell phone) along to my buddy Steve who is very good with the spartan, he may be able to help you.....let me know if you mind or not please....

Post by: rcnut on March 07, 2015, 10:27:53 AM

I've made a few changes in the VX1n. First, I dropped the collective range to +/-11 degrees. Second, I dropped the idle 1&2 50 rpm's, so now its 1900 and 2000. Then I reduced the expo on the tail hoping to get a faster tail response. And, I increased the tail gain as I noticed it was a bit mushy. I also dropped the cyclic gain by 2 points.

So now its set and ready for a test flight!Hoping to go out this afternoon, the weather is supposed to be nice…we shall see! ;D

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on March 08, 2015, 02:11:27 PM

Standard hs for the n7 is 1750, 1850, and 1950 to keep the 105 in its happy place. I have run mine up to 2100 and 2150. She fly's like an animal but not happy. 2000-2050 would be tops. It doesn't need that high hs as light and efficient with the gear ratio is has. 1950 does me great other than piro loops, BC I am a right ruder guy on them, and right rudder loads up a little more....

Post by: rcnut on March 09, 2015, 08:40:00 AM

So with Mark on vacation in the Florida Keys...it was time to fix my stuff. With that said...

I started out with the Rave in the hopes that bearing noise was finally gone. It was! And...Oh the horror! I ordered a new bearing set for my O.S.105HZ from RCBearings (good thing I did!). When I removed the main bearing, it became obvious as to where all the noise was coming from! The main bearing was totally shot. Heavy pitting all around the inner race, and some on the outer. It was the inner that was giving me the noise issues. Had I continued to run the motor that way, it would be a matter of a few more flights, and "bam," time to order a new motor!!! :(

Now my Rave is purring like it should. I put 3 flights on it, and boy was that ever a treat! I need to do a little tweaking with the collective pitch, as the plus side seems weak, and possibly a bit more aileron response. Other than that, its good to go!

Next up was my new Synergy N7. Ok, it is still a nightmare to fly, but I think I figured what's going on with this heli! Its in the links! They are so tight that the Spartan Vortex VX1n controller is having an issue with it. At first I thought it was the cyclic gain being too high…nope. Then I thought I had dialed in some "sub trim" in the menu…nope. And I thought the aileron tilt problem was only in idle up 1&2…and again, nope, that wasn't it.

So with no distractions and spectators watching…its time to figure out this problem I'm having, once and for all! Well, actually there were 3 people watching somewhat. A mother and her two children were walking the school grounds and would walk past me…from time to time, but not just standing there to watch me fly!

First flight, I lifted the N7 off the ground and placed it into a hover. I let it sit there a bit to watch it. Then I moved the aileron stick a little to the left and right quickly to see how it would react. It seemed to be fine, but then it started to happen…it twitched all by itself to the left, ok… I flew it around the field a couple of times to see how it would respond. A couple of times it moved itself to the left, and I would correct it. Then I tried idle up 1, it didn't move when I switched into idle 1.  ;D

Ok, so a couple of more laps around the field. Everything seemed good for the time being, but it didn't take long for it to start acting up and making aggressive moves all by itself! Wow, this is interesting! I tried idle 2 and it seemed to settle down some. So a few more laps around followed by some hammer head turns. However, the rudder is responding better! A couple of aileron rolls, and WATCH OUT! Man those are lightning fast!!! Ok, mental note, turn down the aileron roll rate!  :o

One more lap around and oh, oh! The clutch let go! I know that feeling all to well. Ok, switched into throttle hold and head back towards me. However, it became a battle with the ailerons as the VX1n controller wanted to over command the ailerons...the dreaded roll over! Oh no you don't! I managed to fight it quickly without panicking (but lost head speed in the process), switched into normal mode and switched out of throttle hold (all this in a blink of an eye...muscle memory at this point!). Thankfully the clutch caught and began spooling the rotor head back up in time to avoid smacking into the ground…saved it! :P

I brought the throttle to idle and let it sit for a moment, then throttled up and returned the heli close to where I was standing. As it was hovering, that's when I noticed the swashplate seemingly fighting the tightness of the links. I experienced this before with a newly built heli, but it normally goes away in a few flights…not this one! Because of the cold weather, it would take many flights to break them in. The warmer/hotter weather would have made this task faster as the plastic links would have stretched some, or just enough. Then with many more flights, the exhaust gasses would have acted as fine sandpaper (a rubbing compound) and formed them to the balls. Well, that's my thought on this subject.

I also noticed, through the mist of everything else, the collective pitch sensitivity has changed quite a bit. I set the total pitch range to +/-11 degrees, now it feels a bit sluggish. Ok, so I'll set it to +/-12 degrees. The 11 degrees made a difference in the collective "pop" feel, it did change the resolution of the pitch range. The collective stick is no longer touchy!

So later today and after 4 flights, I popped all the links off and ran the Botos link sizer through them again. This time making sure they are a lot smoother. However, I found that I damaged the large sized link ball with my link tool/pliers. It flattened the cutting surface some...great! NOT! Ok... Ah, umm, not sure if this will work...but I tried the heat method. I snapped the link sizer in the link and used my Bic lighter to lightly warm the link. 3 fast passes with the flame and several turns both direction...whoa la, almost perfect!

My N7 is ready for yet, another flight!

I tried the N7 first as I was hoping the problem was fixed...well it isn't! >:( With the links looser than before, it has become very evident it is the VX1n controller messing up! I even dropped the cyclic gain to 40, from 50 factory set. So tonight I will reset the controller, re-flash (software update) both data pod and controller, and try it again! If it doesn't work that time around...I have a spare AR7200BX that I will use and then see what happens!!! Chances are it will fly just fine!

Post by: rcnut on March 12, 2015, 10:12:39 AM

Yea I hear ya! I thought I had found it as well, but apparently not. I'll try the reprograming and setup proceedure once more. If it doesnt work, I'll try the Beast X controller. I know that one works well, it was in my Team Nitro Whiplash. I logged 28 flights on it. So I know it works great.

If this does happen, I'll bring the VX1n with me. I have one week to figure this out! ...and get my Rave fixed!

Yea...I had a fan hub failure yesterday with the Rave. the fand and clutch broke away from the hub! Go figure that one!!! It has been an adventure with this heli lately. It all started with the swashplate coming apart 2 years ago. This led to the tail output shaft, control arm, yoke, bent. The mainshaft bent, both mainshaft bearings shot, and then the main bearing in the motor. All this found one at a time. Wahat I can't figure out, when I replaced the swashplate, the heli flew fine, no shakes or wobbles. Except for a slight foaming in the tank, which became excessive over time. And then I started chasing on problem after another.

About the only things left to replace is the head and feathering shaft...

Update

I ordered the Rave fan hub from two different places in the hopes I would have one by Friday/Saturday at the latest. Wrong!!! >:( So much for two day delivery! Oh well, Monday then…

Now, with the N7, yep the hub was loose on the crankshaft as if the shaft grew 2-3mm :o ??? And there was another thought about the bearings in the motor possibly being bad (loose) that would cause the foaming in the tank. So…while I had the motor out and mostly apart, I replaced both bearings. The main bearing seemed fine, but the front bearing was a different story. Somewhat gritty and loose, side play.

When I installed the fan hub, the nut bottomed out on the shaft leaving the hub loose once again. And to make a long story short, and after three different combination tries, I placed a washer under the nut and all is well with the hub…I hope! ;D

I reprogrammed the VX1n…and data pod…and walked through the full setup. I found one item that I didn't do, assign the gov channel to the gear (for flight mode), so the VX1n wasn't controlling the throttle, just the curves in the radio. Instead of using the "Bert K" settings in the "Style" wizard, I used the "3D" settings and I'll adjust to my likings. Maybe there was something in the "Bert K" that didn't bode to well with this heli.

So later today, I shall see if this problem is finally fixed! If not, I'll use the AR7200BX controller…

Post by: rcnut on March 16, 2015, 10:53:38 AM

Well yesterday was a bummer! :( On the N7 startup, the fan hub broke loose (AGAIN!!! >:() and ended that test flight. Now hold on...cause it gets better! :-[

I brought my Agile 7.2 to temporally replace the Rave (until the fan hub shows up), however...I left the radio (DX8) at home! So no flying that heli...

I also brought my Goblin gasser. I have that heli programmed into my new DX9. I managed two flights on it before I botched the last auto. I lost too much rotor speed and landed a bit hard with a slow rollover. I broke one blade, snapped a link, and broke the elevator servo arm. That's all I found...so far.

Those are the three helis I was planning to bring to Birmingham at the end of this week! So I have some fixing to do!

On a good note...I was able (finally) to do multiple piro-flips in a row. For me, that more than 3-4 flips... ;D

Congrats on the pro flips!!! 

Ray, when your installing the hub on the n7, you are using both washers, right? The one supplied with the motor first, the hub, then the second one, then the nut, right?

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on March 17, 2015, 07:15:11 AM

What nut??? I'm thinking....................OH!!! YES! While munching on an apple, my mind thought you said "then the second one...", and my brain finished it off with "from the kit." LoL! 

Yes, I installed the second washer under the nut. However, it spun, so I found a lock washer that's a perfect fit on the crankshaft. I will use that washer and then try this again.

Yes it feels / felt really good to do those piro-flips! I've been working on them for quite some time now. The only problem I'm having now, is adding too much collective pitch. So my piros keep climbing, which is better than before...falling, that or moving sideways...bad collective timing. Its been a struggle for sure, but I kept trying and trying until I stopped thinking about it and just did it. And that's when it all came together.

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on March 17, 2015, 08:04:37 AM

0 collective for 3/4 of the flip is what really helps me. i will "catch" the heli quickly enough to keep it from moving, but staying at 0 as long as possible keeps her as still as possible. also keeping the prio rate under control and at a rate that you can handle, that is probably the most important thing.

good deal on the motor. its just weird your having that problem, that is a new one to me. lol

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on March 18, 2015, 12:13:23 PM

I have the motor back together again and in the heli, but I'm not happy with it...the clutch isn't seated right. I was planning to test fly it later today, however, I wait until I show up Friday morning. And instead of a test flight...I might buy the NovaRossi 91 for the N7 with a new fan hub. I've been reading up on this motor and I'm getting excited about it! Then I'll use the O.S.105HZ-R on something else.

So that's about it for now. I shall see what transpire at the fun fly! ;D

Title: Re: My first Synergy... the N7 build!

the guy with the rossi .91 is out of town until next week though, you may want to put the 105 back in it for this weekend. we will talk Friday. be careful on the way buddy...

Woo Hoo! My N7 is flying a lot smoother! Thanks to the guys at the B-Ham fun fly!!! ;D These are some amazing people, all I did was ask one person for help and 10 people jumped in to help. Matt Botos was a big help with the fan hub issue. It was assembler error (me ::)). Matt and I had a great conversation about the Synergy N7, some of the great ideas he incorporated into the design. Matt & Amy are just wonderful people! ;D

And now to fix the O.S.105HZ-R problem…aka needle and reg issue. The quirky Spartan Vortex VX1n problem was due to the factory tape. We replaced it with some 3M gray tape and now the N7 flys hands free! Well, for several seconds.

The first day has been awesome! The people in Alabama are wonderful!

Chris, I wish we had more time to hang out and get to know one  another a bit more, but you were busy setting up helis, and that's ok…maybe IRCHA or next year!

Alan, thanks again for all the help you provided with my N7 issues (ex. the dreaded O.S.105HZ-R issues!), and just hanging out. I can't wait for next year…even though the drive there was long and boring! LoL!

Post by: rcnut on April 01, 2015, 12:29:40 PM

Finally!!! ;D

I pulled the regulator off of the motor, opened it and gave it a good alcohol cleaning! I was able to get out and test fly a couple of helis yesterday, the weather finally turned nice. Since finding the issue with my N7 (the factory tape), I replaced the factory tape on my second Goblin Gasser, and now it fly great!

After some minor carb adjustments, the N7 is fly great! I need to adjust the programming some...in the meantime, I was able to get two flights on it from start to finish. The first flight, I ran it out of fuel! The fuel magnet did a great jog of emptying the fuel tank!

Close to the end of the second flight, I played with some autos. Changing to the shorter (695's) Rail blades, made all the difference in the world. I was able to get slow descending autos, somewhat like what Matt does.

So once I make a few adjustments in the Spartan Vortex... ;D

My first 8 flights all ended in autos because I was having so much fun, I didn't hear my timer going off.  :D  On the plus side, the N7 is an absolute blast to shoot autos with.  It just seems to float down forever.

Post by: rcnut on April 05, 2015, 07:08:28 AM

Thanks Rodney! ;D

Yesterday, I added another two flights on my N7. The first flight, it was performing great. The second flight, the regulator started acting up again! So it is coming off until I get the parts to fix it!!!

But in the mean time, my autos are getting really long! This is awesome! Even my buddy Mark was marveling how well it flies, almost to the point of pushing the button to buy one! This is one super great heli! (I would of used the word "awesome", but I have already used it and didn't want to sound like someone who didn't know any other words besides "awesome")

Post by: rcnut on April 08, 2015, 09:51:49 AM

Ok, I removed the regulator and changed the line coming from the motor's backplate to the muffler. So now The O.S.105HZ-R is now an "HZ"...non-pumped.

While I was working on the carb, I used the opportunity to check my heli over...all the nuts, bolts, and screws. Everything was tight except for...one motor mount bolt was missing. An easy fix! This Saturday is looking very good for a full day of flying! Sunny, 60+ degrees, and 0-6 mph winds. Mark and I have made plans to fly all day! We are bringing our arsenal of helis! ;D

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on April 08, 2015, 10:52:33 AM

sounds like a great weekend to me! glad you have your n7 going well now!

i use denatured alcohol to clean everything with, it helps with the bolts. its hard to get all the oil out of every nook and cranny on the heli, that stuff does a great job of getting into very small places and removing the oil.

Post by: rcnut on April 09, 2015, 07:59:23 AM

Hey Alan,

I haven't tried the OS as a non-pumped just yet. I will this Saturday. As for the Spartan issues?...not a one! ;D There all gone!!!

;D ;D ;D

Once home from the fun fly, I changed the tape on my goblin gasser (which had the same problem as my N7), and now it flies the way it should! So I'm supper happy now

Saturday should be a blast! I'll be bringing the following helis; the Rave ENV 90, Synergy N7, Mostro nitro, and the Goblin gasser #2. I want to see how the Synergy N7, Rave, and Mostro stack up against one another.

I know the Rave is a "big air" / FAI / 3D heli. The Synergy (from what I've read...could be completely off) more of a 3D machine. And the Mostro...pretty much a 3D machine. So I will find out who is who.

My flying style is more of a combination of FAI/3D, mostly technical...controlled. I like a mix of big air to short and sweet in your face to smooth transitions.

Title: My first Synergy... the N7 build!
Post by: flyalan on April 09, 2015, 08:52:09 AM

The N7 can be anything you wish. It's all in the setup.  Granted the power of the 105 does make it a monster. The N7 I am currently building uses the 91 HZ-R which is ample power but will require more collective management.
A buddy has the rave and it is also 3d capable but nothing near the N7. He converted his to electric which changed things a good bit.

I kind of gathered that after the first few flights. The 105 is an awesome motor for the 90 size helis. It definitely helped the Rave ENV for the good...in my opinion.

I flew my Rave with the O.S.91HZ and the motor was always on the ragged edge for me. And I was working on collective management skills as well (which didn't help matters, many motor rebuilds!). The 105 really helped my Rave to the point of not using all the power it can provide. I'm using maybe 70% of its capability now. However, the Rave as an electric...watchout! It becomes a monster!

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on April 13, 2015, 03:07:39 PM

Ok N7 fans! I'm still having motor/carb issues. Just removing the regulator doesn't work. The carb the O.S. company picked was/is designed for a reason. So I'm using a cerb from an O.S.91HZ motor. I can always richen the carb if needed versus leaning the other carb to the point of closing off the main needle. If this doesn't work, then I'll try the original carb and try it again. And if that doesn't work...I buy a non-pumped motor...

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on April 14, 2015, 09:21:50 AM

you can get the proper needle seat, that will fix your issues all together. that is exactly what i had to do with mine when i got it.

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on April 15, 2015, 07:45:51 AM

I received the new needle seat for the regulated carb and its installed, just haven't tried it yet. The weather for tomorrow is almost perfect! I will be taking 3 helis to wring out.

It kind of funny...at the B-Ham fun fly, after finding the controller issue with the N7 was the tape, and my comment about my Rave using the factory tape... Well, this last weekend, I was having issues with my Rave not wanting to fly the way I wanted it to fly! It was if someone was trying to take over for me! I was able to land without any problems. Now it has the 3M gray tape!

The Mostro...I almost burned that one up! Literally!!! :o :( :'( It was my fault for the dead short, but caught it in time and prevented a major disaster!

Title: Re: My first Synergy... the N7 build!
Post by: Mike Spano on April 15, 2015, 08:45:03 AM

very nice! sorry about your mostro though....  i think you will find that new seat will do the trick, it fixed mine right up!

just take your time and clean everything very well. its very easy to get a small piece of debris in the carb when that seat is being removed, or is already out. i usually lay my heli with the carb down towards the table while the seat is out to prevent anything from getting in it. like dust floating around, or some dirt coming off your arm or hand as your working over the top of it.

...sorry about your mostro though.... 

Yea...its fixed and works, thank God! Like I said, it was my fault. I used the data pod to adjust the feel of the heli after the 4th flight. I plugged the data pod port in with the second power wire when I was finished.

When I was ready to turn the controller on for flight number 5, the power wires were dead shorted! It melted the positive pins on the Spartan Vortex controller, and it was going to town on the power wires I made for the controller. Without thinking, I reached in and yanked the power wires off in order to stop the short from destroying the LiPo up front and burning my new heli and back of my truck (which had 5-1/2 cases of fresh fuel!)

LiPo sitting up front with a long 12 gauge extention running to the back with a "Deans" to 2 "spektrum" connectors.

Considering I messed up the controller and it would cost me to send it in and have fixed...I repaired it myself. Having a degree in Electronics, I have a selection of header pins. So I opened the controller and inspected the damage. Then I cleaned the remains of the solder on the back side of the header board (the small rectangular circuit board holding all the servo pins). I used two header pins from my surplus and soldered them in. I checked the circuit trace to verify continuity, and then applied power. It works, and now ready for more flying fun.

As for the N7 carb issue, I'll try the non-pumped carb first, see if that works. If not, I'll go back to the regulated carb with the new needle seat and start over. I wish I never bought the motor!

Guys is there a way to check for a bad needle seat on the 105 aside from experiencing tuning issues? Where can I get the replacement seat from if mine is bad?

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on April 18, 2015, 07:00:30 AM

The needle seat issue is only with the 105 pumped motor. To find out if yours has the wrong seat, you would need to measure the opening. Or call Hobbico for a free replacement.

Newer models should have been fixed. It's the older models that had the problems. I would go with it. Break it in as normal. Once you get to the break-in point, it should run fine. If you have problems tuning it, then look into the seat issue.

;D  8) ;D             8) ;D 8)       Success!!!      ;D 8) ;D            ^;D    ₈₎   8)    ;D 

As you will recall...I was having carb issues with the O.S.105HZ-R, the pumped motor. Well I removed the carb and use a spare O.S.91HZ carb to see if it would work. If the 105 needed more fuel, this wasn't a problem as I can open the needle valves a lot more versus closing them. As it turned out, the carb worked just fine! I had to open the idle needle a lot! But it idles very nicely now. The mid is close to 1 turn out (about 1-1/8 to 1-1/4), and the high is now 1-5/8 turns out. The motor is on the warm side, about 7 seconds before needing to remove your finger! So I'll leave it there for a while, I'll let the motor get used to this setting.

As for the N7, it is now one rockin heli! I only got two flights on it due to the rain…and ran out of fuel both times! I was having so much fun, I forgot to pay attention. ::) I think I need a bigger tank... I made some more adjustments to the controller, but didn't get the chance to test it out. Now I need to tune my Rave like I have the N7...and then maybe the Mostro, I'm still not sure about this heli flight wise.

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on May 03, 2015, 08:19:18 AM

Mark and I made it out yesterday (Saturday) for some heli flying fun! I put in 9 flights on my N7 and it is fly great! I'm still having slight carb issues, getting the needles set right. I think I'm going to need a header tank as when I get close to the end of the tank, it goes lean. Also, I will need to find a better way to empty the tank in flight. The fuel magnet won't suck the last 1/8 of the tank. Weird??? :o Out side of that, this heli continues to impress me!

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on May 05, 2015, 09:28:23 AM

Oh yea!I'm liking it a lot!!! ;D Wish we lived closer, I'd let you try mine!

I don't know if I told you...I totaled out my Rave. I was flying around inverted backwards and the muffler broke off and went through the blades. Just the replacement parts alone is $250-300 away from a new kit. The electronics and motor survived. The sad part, it was a free fall from 50 feet. I hit throttle hold once parts started rain off my Heli. Then I hit throttle kill seconds before it hit the ground.

It looked like the space shuttle that broke up on re-entry! I've never had this happen to me before. A buddy in Chicago had his airframe up for sale. I struck a deal and picked it up Friday after work. By Sunday the new Rave airframe was ready for a test flight. However, there are many flights on this Helli and I need to address a common problem with this Helli. The tail output shaft bearings. They are pressed into the carbon fiber side plates with a little glue. However, the nitro fuel errodes the glue in time causing the output shaft to wobble slightly. The tell tail sign is extensive foaming of the tank.

Its not the hard to fix really. I pull the side plates off, remove the bearings (flange bearings), clean everything well, and then JB weld the bearings back in. I can get hundreds of flights with this fix, unless I smack the Helli into the ground! LoL!

i like my spartan on my E5 too, feels amazing. very locked in, and doesnt have that "disconnected or delayed" feel of the vbar.

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on May 26, 2015, 05:44:27 AM

Saturday… Mark and meet at out practice field. Bill and John were there warming up with a flight each. Mark replaced the main gear on his Raptor G4 with a CNC gear designed for the O.S.105. It put the 105 in its proper power band. Then he bought a set of the Zeal performance blades to try out!

First flight, Mark's G4 sounded ok, as I was setting up my N7. So I walked out to ask what he thought of his heli with the new blades and gear…he just handed me the radio and said try it, ok. The head speed was lower than before, the tail was sluggish (oh yea, he replaced the tail blades with longer 112mm blades, so it should have been very touchy) due to having 27% expo in the radio, and the motor was on the rich side.

So I adjusted the motor, made changes to the radio, and then tested it. I was low on fuel and wasn't able to run it through much. Mark said land and let's put more fuel in it! So we did. Second flight was a lot better, but the gyro was too high, the dreaded oscillations. More tuning of the radio and now it's a lot better. One more carb adjustment and a change to the throttle curve…WOW! The 105 came to life and it was ready to "jam!"

I gave that G4 just about everything I could think of and it was taking it with gusto! I pulled some fast "wall" maneuvers that scared the crap out of Mark! He was waiting for the blade to fold, break! But they didn't, they held up fine. Then it was auto time! I wanted to see how well these blades would auto on the G4. They are great, super slow autos to rock'n fast!

After that flight, I handed Mark his radio and said have fun! He was too excited to fly and needed to calm down. His head was swimming with what his heli was doing and the speed of which it was moving. That's fine, time for me to burn some fuel!

I pulled out my Synergy N7 to use to finish off the last of the the 20% fuel (Mark and I bought many cases of 15% during the Toledo show). The third flight was a mixture of 80/20, 80% of the tank with 20% fuel and 20% of 15% fuel. The N7 was running great, and I was a bit concerned switching to the lower nitro content as I would need to readjust the carb. But the forth tank, and the others that followed, I didn't need to change a thing!

As a result, my O.S.105 ran "better" on the 15% versus the 20% nitro content! Go figure that. I started "hammering" on my N7 as I did on Mark's G4. I couldn't get enough of it! ;D It was dialed in perfectly! Well, Mark and I spent flight after flight having a blast, and wishing the day wouldn't end. We never got the chance to fly our Goblin gassers, as we both brought them to fly.

As for my Mostro nitro heli…I think I will put it up for sale. It's a great flying heli, but it doesn't fit my flying style/feel. Every now and then you find that one heli or airplane that you really like and the Mostro just isn't it. So I'll sell it...and possibly buy another N7! 8)

I pulled my Compass 3D+ out of moth-balls this weekend. I forgot just how much this little heli can jam! The only problem with it, its no longer in production. :-\ So I'm thinking about upgrading it to the N5tt... I'm waiting for Bill to finish his N5tt...he wants me to test fly it for him!!! If I like it, the 3D+ is history! LoL!

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on June 03, 2015, 09:03:14 AM

Bill's Synergy N5tt...

I had spent a good portion of Saturday finishing his Synergy N5tt. Mark and I flew Sunday and Bill was nowhere to be found. Bill's excuse was babysitting the grandkids...yea right! Granted he probably was, but missed out on a good day to fly! And I to test fly his N5. So we gave him the "business!" He took it very well, and then informed us he left the N5 at home?!!! We made him go get it! He had his son bring it out.

I looked it over one more time, checked the carb needles, checked the controls, and then powered up his heli. Now to maiden this new heli! The motor was acting goofy, erratic rpm hunting, or rich / lean, rich / lean...repeat! This is weird, never had a motor do that before, plus the tail was sluggish. Ok, open the needles some more, make an adjustment to the gyro gain setting in the radio, and add a bit more expo to the elevator and aileron.

Ok, now its acting better, however, the head speed seemed a bit high? After messing with it here and there, it was time to fly this super light heli around the field! Wow, this little heli is awesome! It flies as if it’s on rails, the controls are rock solid, has plenty of power even rich, and it wants to go! I felt very comfortable with this heli, even though I have it setup somewhat tame for Bill and the fact of breaking in a new motor.

The second flight surprised us, the tail stopped working on lift off. Come to find out the grub screw in the tail hub departed! Ok, I had some spare grub screws, and had to harass Bill for some "shotty" building skills! I fixed the tail and its time to go back up! But flight number two started in with the motor acting up again. This time it went lean and now I have to find out why and fix it!

Long story short, it was the fuel clunk getting stuck in the corner of the tank. I explained to Bill, and his son, how to fix the clunk (filing a slot at the end of the clunk so fuel will flow in without suffocating the motor...running lean), and in the meantime, I shortened the clunk line, even though the line will stretch in time. Flights 3 & 4 were much better, a smoother running (consistent) motor and lower head speed. We were marveling at how well it was tracking as I flew forward and backwards…and a little inverted forward.

I was curious to who this heli would feel...now I know and I want one too!  ;D

Title: Re: My first Synergy... the N7 build!
Post by: rcnut on July 08, 2015, 02:46:44 PM

Well last weekend I practically melted both clutch stack bearings. Apperantly the fan hub worked its way up the crankshaft and forced the clutch into the clutch bell, and into both bearings. On the 5th flight for that day, the clutch stack locked up hard. I had to cut the start cup and shaft off as the grub screws acted as if they were welded in place.

Once apart...well it was very ugly inside. The ball bearings were heated so much, some of them crumbled when I tried to move them out of the way. So I ordered most of the stack and this time I am installing the YS120SRX motor...with the Hatori 120-3D pipe.
