It has arrived, that is the good news :)
Bad news need to wrap it and put under the Christmas Tree and wait longer. :'( ::)
-
Nice.. enjoy the build!
-
Nice! At least it's only days away now...
-
So pull the contents out, wrap the box, place it under the tree, and then get to building it in your man cave. ;D

I inserted the fuel clunk, fuel tank Stopper and fuel tank stopper grommet #(106-810) and it seems to me that
when I have to replace the fuel line later that is not going to be easy to take out, or it is that dry and new that
the fuel tank stopper#(110-331) will slip out to put a new line inside? :-\
-
It is challenging to get it out. I have a set of round needle nose pliers that I use to get it out without damage. You can use a round screw driver to pry the grommet out. Having spare grommets on hand is a good idea.
-
Grommet should be replaced anytime you remove it. It’s very easy to tear.

Oh expendable rubber grommet , makes good sense.
Another question. How come the starter shaft is thin
walled on the one way bearing in the clutch fan assembly?
-
I've done the same but a method i use now and i find it quite effective is to get a 1.5mm or 2mm hex driver and using the plain shank of the driver and roll it under the lip of the stopper so it doesn't damage the stopper. Using the driver to pull the stopper out slowly, you can switch sides if needed as this can help the stopper come out, this should allow you to remove the stopper and the grommet without damaging either the stopper or the grommet.
Hope this helps,
Cheers,
Ross
This suggestions works well for future fixes and disassembly of rubber grommet from the fuel tank :)
-
Pull the plastic stopper until you can work a small zip tie between the stopper flange and the grommet. Tighten the zip tie around the stopper and pull the tag end rotating it around and the stopper will pull right out. Super easy.
-
:'( :o OOPPS I got the wrong throttle servo, the BK 7005 multi size. I did not realize that the throttle servo
would be a mini throttle servo cut out on the frame pattern. :(. I guess I will get the BK 5001 and have two tail
servos, one for back up. :)

That is an excellent solution :) :). I would never have thought of that one. Thanks

Finished putting the main frame together, nothing tight. I couple errors 1) was the mini throttle servo and 2) the mid mast block was put upside down.

Worked on the N5C over the weekend holiday. Still waiting for the throttle servo and ball sizer, should be here
shortly. My receiver and and telemetry parts came in from Graupner. I also had to make a special order for the
Push Rod End (305-311), they must not have package them in the kit for some reason, so I will waiting for
about a week or so for that to be delivered. No worries, still have plenty other things to finish up on and learn.
Found out why the starter shaft is bored out. It fits the crankshaft thread OD inside.
Also while ordering the push rod end came across the Torque Tube End mount upgrade version, so I order that
also. Will it be alright to fly with socket screw and nylon nut holding the old version of the TT end as
assembled? Or will there be a vibration issue with the tail?
-
No the scew and nylon nut on the tt end is fine.

Finished the Assembly, installed the servos , one slight error, I recently purchased a BK Mini servo and the
the motor that sticks out of the servo case did not fit the servo square on the the frame, so had to file a little
hump on each side of the rectangle on the frame for that particular servo to fit. It is the BK 5005 HV mini servo
Overall this nitro Kit is extremely enjoyable to assemble. Now for the electronics , receiver, battery, servo
setup. Looking good for not this weekend but the following one for the maiden flight. ;D
-
Nice!
-
Werd!

Few delays , had postpone the flight schedule. Slight learning curve on the mz 24 pro radio trying to learn the navigation of windows and function of it.
Do have a question about the flight characteristics of the tail rotor.
Looking behind and top of the tail blades what direction does the leading tail blade point towards to, to counter
the torque? I do not want to cork screw the heli in to the ground during spooling up? :'(
Thx

Damper,
Put your finger on the bell crank and slide the tail to your left. This will simulate the helicopter turning right. The bell crank and tail control rod should push back to you as you stand behind it. (https://uploads.tapatalk-cdn.com/20180124/8baf63fb9c4bda7a5161c710d922f2e6.jpg)
This picture is full left input. Remember the N5c turns clockwise on the tail so the leading edge is forward looking from the top.

Thank You! and Thank You Again :)
I greatly appreciate it
-
Finished the set up and be ready to go next weekend. Hopefully just a few minor adjustments and be trusted for
the airworthiness certificate at the airfield. All the safety criteria range testing and engine idle , throttle hold and
throttle cut , fail safe, etc. :)
-
Group pic . Just giving them a intro to each other. The Nexus does fly much more for static display. Rave 450 goes both places, mostly at the house though. Raptor 70 mostly doing autos with and mostly just mild circuits, the SE Raptor was the work horse but I believe it is going into semi retirement.
Thanks for the help and advice and the helpful tips. :)
-
Got her started up and realized that I put the auto hub upside down :(. No problem, came here and ask for some advice and the simple solution was to flip the main gear over .
Started her up again and the clutch is engaging nicely.
Perhaps this weekend will be day , weathering permitting. Rain in the forecast >:(
-
well the weather is not cooperating this weekend. But I was able to do some baby hovering with it today.
I have too high of throttle for normal flight right now not hard to control but very sensitive in the cyclic. Some
expo should take care of that and toning down the throttle curve for normal flight.
That OS 55 hzr wants to run like a scolded ape hate to see it in idle up right now. ;D

Yes, that's great to hear. So no worries about power! I was a little concerned coming from electrics. Glad you got her up in the air.

Found out why the swashplate was acting sensitive and odd. I forgot
to loctite the washout control arms. Fortunately they are 23 mm bolts, but
on that cause a tail rotor strike on the ground doing an auto when I realize
I did not full control of the cyclic. Broke the front transmission gears. Not
A terrible repair . It could ended up worse than it did.
-
After the transmission repair and loctiting the control arms and One do over on changing throttle and pitch curve she settled in with a little sensitivity on the roll side but very much controllable.
Tomorrow morning taking her to the field probably add some 10% dual on the roll. I did add 15% of expo but I think I will deaden the center for it too much if add more. If everything goes well there and tuning the engine I will in good shape for flying circuits . :)
-
The weather has not really been cooperating :'( . Did get the airfield last Tuesday briefly and got it in hover and everything seems good after the technical difficulties. But the rain came in and was unable to tune the engine. Need some rain relief ::).
-
Last Saturday had a change to fly couple tanks . Still tuning the engine. It just
seems I cannot get to the field long enough to do any good really. This weekend
likely chance of rain again :'(. No worries . I got alternate plan. Bought another
synergy. The synergy nc belt version.
Couldn’t help myself. Got a good deal for the airframe and bought a new OS 55 HZ
Did not want the regulator on this one. , few servos, another battery and
receiver be ready to go . Should be here late next week . ;D
-
LOL! Synergy helicopter fleets tend to grow pretty rapidly for most people after they get their first one. :D
-
Rodney.. ain’t that the truth!

Ok had a few minutes ...
Had some unfortunate incidents with my OS 55 hzR engine. Basically blew hole though the piston while tuning it.
Two errors 1 was turning the mid instead of the high needle and second I had a small leak on the fuel line on
the nipple of the fuel tank :-[. The dilemma I was in; should I pull the parts out the new OS 55 hz engine I
bought for the Synergy N5c belt version or order parts. I began looking for parts on line... as luck would
have it ,no store had all the parts piston, piston pin , clips , liner and piston ring. so I waited a few days
thinking about it so I order a few parts from ebay what they had on amazon. The piston ring was the worst to
find. No big deal 2 to 3 weeks was not all that of a wait. I didn't feel the need to break down a new engine just
for parts, :-\ new parts on the way from 4 different locations. Couple days past and I just remembered the
Only Fine Helis. They had everything I needed. I still do not have all the parts for yet from the other online
Stores. So I was anxious for the weekend I would have a few hours on Saturday to play so I did tear down the
engine and replaced the parts.
I did not get to learn or sat down to learn when I first started this hobby to actually engine tune, radio set up effectively it was really plug and play. So this time I am taking the time to, found last weekend that
playing with the pitch curve helps a lot on the stability of the heli . I was noticing on normal flight mode I subtracted a point on the pitch from 25% to 35% to 45 to 50%. I removed the 45% and became more stable.
Well there the light bulb came on.
I did get to burn 3 full tanks and on the third idle up a tank but I am hearing changes of the engines. I am still
not quite sure what it is telling me and the idle is seems a little off. But I know no air leaks and thick smoke.
I want say Thanks to Only Fine Helis for having everything in stock. They was at Birmingham last weekend.
Although this mishap I got to install the new parts in the new engine. Running behind schedule for the
for the belt driven version to be coming on line and of course the new N556 is delayed a few months.
Happy flying my fellow pilots.
-
ALright ALright Alright 8)
Finally got the airfield since I had the day off. Got the engine dialed. Sweet. Running great.
That warm and fuzzy feeling felt good. Burned five tanks till my receiver battery is on 10% of course this a 3000mah LiFe battery, running all BK servos.
I also got the old Titan SE with an redline 53 and a bearing overhaul in the air for couple times still faithful as ever.
By the way is anyone have some old redline 53 engines for sale?
Happy Flying Days are back.

Sweet!
