I've received a ton of questions about the TT Conversion for the E7 lately (rightfully so because Christmas came and went with no TT under the tree) so I've decided to post the details here.
In mid December, I had to make a tough decision regarding the original shaft driven tail box. I could either release the original design at Christmas as I promised or ......... take a bit longer and release something I felt was much better than my first design. Since you only get one chance to make a first impression and since many Synergy customers have three feet of snow at the flying field, I decided to go ahead and take the extra time to make what I think you guys will really enjoy. Synergy has always been known for its top quality products and I feel now is the time to take it to the next level of quality. The new tail box is completely different and will provide a solid rear transmission for the E7.
A few details -
1. All Aluminum Tail Box which is the same exact weight as the original carbon design.
2. Four point bearing plate mount system to ensure proper bearing alignment and rigidity.
3. 20 tooth Mod 1.25 bevel gears which are larger in diameter that 24T Mod 1 Trex 700 bevel gears. These gears will withstand some serious abuse from pro pilots and ham handed novices! :)
4. Longer carbon tail fin to allow for longer tail blades
Check out the pictures below.
I have quite a few flights on the new tail box and even though the performance is the same as the last tail box, I feel better about the whole package.
Thanks for being patient, I hope you understand I only want to bring the highest quality products to your hands.
Sincerely,
Matt Botos

Thanks for the update and I totally support the change in plans. I really like the new tailbox and am glad you've gone this direction. Longer fin is bonus for the guys like myself that want a little lower headspeed and longer tail blades. I won't spoil the mood an ask when it will be available. ;) Keep up the great work.
PS: The forcast is for snow this week in Seattle, first of the season.

That's why we are here flying Synergy machines, I'm a huge fan of the new design!
Great Job Matt!!
Rob :)

Thanks for the information Matt, I completely understand and am thankful for your decision to make sure it is bullet proof prior to release.
One question, why the need for longer tail blades? Does the TT change the tail drive ratio that much?
I guess my real question is, if I am running an e7 with 106 Rail tails at 2200rpm head speed, will my tail not hold as well as it does with the belt?
-
Good info in the tips and tricks section.
http://synergyrchelicopters.com/forum/index.php?topic=265.0 (http://synergyrchelicopters.com/forum/index.php?topic=265.0)
1. Tail rotor performance is relative to your head speed.
2. When running slower head speeds 1900 - 2000 you should increase your tail blade size.
3. When running higher head speeds 2200-2250 you can easily run 106mm blades without issue
4. Heavy cyclic and pitch at the same time (ham hands) will blow out any tail. Adjust your cyclic and collective to meet your collective management skill level.
5. The heavier your helicopter, the higher the disk loading. The higher your disk loading is the harder your tail must work to counter act torque. Run appropriate size tail blades if you are running heavier batteries.
Here are my recommendations based on head speed.
Head Speed------Tail Blade Size
1900-2000 110-115mm
2150 110mm
2250 Rail 106mm (they have 30mm cord for nearly the entire length)
-
Oh man that is sweet :)
Looking forward to getting one of these.
-
No need for longer tail blades. I am running 106mm blades and it works perfectly.
My head speed range is 2000 - 2200
If someone were to run 1600 - 1700 then maybe they would want to run longer tails blades.
Gregor posted a good reference to this.
Thanks!

Thanks for the explanation. I am looking forward to this not because my bird isn't great now, I just have no confidence in my ability to adjust belt tension ;)

+1 fit the TT and forget :)
Love it

What's the new ETA? Will it be available before March? I've had all the electronics for almost 2 months now looking for a TT E7 to install it in. I hate to be the guy to ask but I've been checking daily, looking for the release date since November. I was hoping there would be a new release time frame but as of yet, have seen nothing.
-
Great things come to those who wait.. Patience "BIG" it will be here before you know it. ;)

Unfortunately patience has never been my strong point.......I just wait because I have too!

An update would really be appreciated.
-
Someone said march to me today funnily enough but a more official answer even if it is an unsure it would be welcomed :)
-
Factory is running production batch right now. I'm hoping to have some available by the end of February. I can't promise anything but I am confident you will be happy with the end product.
Thanks,
Matt
-
Great news Matt, hope their is one in there for me.

Great news.....and you have my shipping address and paypal info.......I'll be watching the mail box!
Tom
-
Great news indeed!
Do we have an estimate on cost? I want to "earmark" some money now :) tax season and all :)
-
Matt,
That is spectacular..... I look forward to picking several up for both of my E7's.
Thanks,
Chris
-
Great News Matt, looking forward to getting a couple of those! :)
Cheers!

I guess I can cut down the tube to fit one on my E6 ? Love TT helis.
-
Having just trashed my E7 in which only the frame and electrics survived Im now doing a complete rebuild. After looking at this thread would it be worth waiting for the TT to come out. Anybody know delivery times to the UK please ?
-
If I was you I'd just get the heli put back together and fly it if you can. I don't like broken helicopters laying around....I'm weird this way. This way your not on the edge of your seat waiting for the TT to make it to the shelves. The heli is fantastic with a belt so why wait.
Tom
-
I couldnt agree more ! It was just a thought while its in bits.
Im picking all the gear up for it on Thursday and should have it back in the air ready for the weekend.
-
That's awesome Rob.....post some video or pictures when it's ready to go or going. We like pictures and video!

Here we go a video of my E7 doing some slow 3D

Excellent flying Rob!
Nice video work too!

Nice flight, what HS were you running? Ive been liking the lower speeds lately.
-
Running about 1950 I think , Scorpion 4035 450 with a 13 tooth pinion and 70% flat line Kontronik 120 with Thunder Power 5000mAh 65c packs as 12s.
-
Very nice flight. Kudos for the very smooth transitions. I like all kinds of flight, but when I watch guys flying smooth or hard "smack", if there isn't smooth transitions between the different elements, it does nothing for me. This kept me watching.
-
I know Matt is Iin Australia, but had anyone heard anymore in a release date?

I am not sure on release date but I got to see it up close and in flights. It was impressive.
-
HAs anybody heard any more on the TT release date please for the UK ?
-
Hey guys,
Just finishing up some final details with pricing. I will be shipping this month if everything goes as planned.
Thanks,
Matt

Awesome news Matt!
-
let's keep our heli fingers crossed !
-
Long time coming, but I'm looking forward to it.
-
Credit card ready! :)
Thanks,
Chris

Early Spring flying is on right now in the northeast ! tooorrrrrqqqqquuueeee tube soon !
-
You are a funny man 4cyclic. I'm sure that if Matt had them he would not let us down and therefore he would let us know that he has them.
I'm also sure Matt knows that we are very anxious to get the E7 TT.
-
Just kidding Steff, I know they are close. :)
-
Yes Sir, looking forward to the TT myself so I can put the E7 back in the air.
I wounder who will be receiving the first shipments?
-
Is it possible to receive mine for tomorrow?
We have a winter FF at our field !!
;D
-
Now that was funny Yanick !
-
Getting close to the end of the month.....
-
Does anyone know if kits can be bought with TT, or the TT is an upgrade-only option to the current kits ?
Also, if kits can be bought with the TT, will they be available at the same time as the TT upgrade, or do we have to wait for the kits with TT to come out at some later date ?
thanks for any insight :)
Nabi.

I would imagine that E7 kits will be coming with a TT kit. It's a must in my opinion. Not sure how they will structure the sales of the current E6/E7 kits though. Nice to have the option for heli sizes but I guess time will tell.
-
By the way, it's April now....
-
We are very close. As soon as I have a tracking number I will let you know when they will arrive in the hobby shops. I know it has been a long wait but it will be well worth it.
Thanks,
Matt
