The E6/7 TT Conversion Kit Retail Price is $199.00. Dealers and distributors will not be happy because I had to remove all of the margin in order to keep you, the customer, happy with the final price.
Release date - The CNC shop is trying to ship TT Conversion Kits next week 4/9 - 4/13. I will keep you posted as to whether that happens or not. I know the wait has been long but the drive system is right and I think you will be happy with it.
Let me know if you have any questions!
Thanks,
Matt

(Edited original content out) Seems like a fair price. Looking forward to getting my ships converted to torque tube.
-
All that for only 199$, you are crazy Matt.
-
:)
-
Sounds fair to me..
Add all that up and see what it'd run ya.

Can I pay now and have it direct shipped to me from the factory ? :P
-
LOL! That would save me some hassle for sure!
Matt
-
Looks great, thanks for the handwork to make sure it is right the first time Matt!!!
Looking forward to this kit!!

This is good value, 2 tubes included, very flexible if you want E6 or E7. I was expecting a higher price than this with all the cnc parts and extra cf fin. Plus the McBeefy design, priceless !
-
Thanks Matt right where I guessed the price to be. Don't know how you did it but looking forward to getting one.
Small price to pay considering everything else about this hobby.
-
So whats the latest update on availability?
-
I have tracking numbers!!
Looks like I should be able to get them to dealers by late next week.
We are on the home stretch!
Matt
-
Hell yeah
-
TT Conversion Kits are here. I will start shipping to dealers tomorrow!
Thanks,
Matt
-
Can I get an "Amen?"
"Amen!"

I'm anxious to try it out.

Matt, is the tail drive ratio the same as the belt drive? - Thanks!

Awesome news Matt..
;D

That's GREAT news!!

cdsexton,
Just a note.....Original style main gear, make sure you pay close attention to page 6 of the manual. The ribs on the original main gear will come very close to interference with the 12T spur gear if shimmed in the original manner.
Thanks,
Matt
-
That looks good with both shims on top. Page 6. Better clearance by the looks at least on mine anyway.
-
Tested the TT on the E6 and feels great. It does however seem tighter than it should be between the main gear and spur gear making autorotation hub tight. I think Matt mentioned this will loosen up but can anyone confirm this... I have the Delrin spacers both on top as per manual.
-
My TT arrived bent, because of UPS shipping package damage. Does anyone know if the N9 torque tube will work, or any other substitute?
Any help would be great, because I would love to fly the TT this weekend.
-
Same here. Elongated the mounting holes also.

Guys,
Do not elongate frame holes. The spur gear spacing is the correct distance based on spur gear mount distance formula. If you modify the mount distance you are putting your gears at risk.
The reason your head is not spinning freely has nothing to do with gear mesh, the delrin shims could potentially be a few thousandths too thick depending on tolerances. Light sanding of one of the delrin shims will allow your auto hub to spin freely.
Thanks,
Matt

I tested my main gear, shaft and tail gear assembly without gear box installed. It did spin freely. Once the gear box was installed the main shaft did not spin freely. I elongated the mounting holes about 1/32 inch. The main shaft now spins freely. It did not take much. Have you built one from this shipment. I did notice that the machining on the drive gear was not as nice as your main gears. Not as clean.
Thanks

Hey Flyalan,
All of the systems that were installed at Bham were from this batch. Mine has been run for hundreds of flights so it is very well broken in.... I'm sure your adjustment will be fine, just have to make sure.
Thanks,
Matt

Hey Alan,
I am on my way back from SEFF and happen to have a TT kit in the back seat. The gears look identical to the ones I have on my helicopter. Are you talking about the 116T Main Helical Gear or the tail transmission gears?
Matt
-
Hey Matt,
The tail transmission gear that came with the TT kit. The milling just wasn't very clean in comparison to the main gears you supply in the E6/E7 kits. Lots of chaff so to speak left on the gear.
I hope to get this one in the air later this week. Will let you know if there we any issues with the shifting of the gear box. Again this was a very small amount.
Thanks
Alan

Gotcha! Keep us posted!
Thanks,
Matt
-
TT drive installed and tested, no problems here.
I did have to sand one of the Delrin shims to free up the auto.
TT shaft tolerance could be a LOT better. The OD and ID vary a lot, making centering one bearing a problem and the other easy.
One drive wobbled badly and predrilled hole was to close to the end.
I still rather build a straight & true shaft then buy an assembled untrue one.

Thanks for the heads up on this, I did have to move the shims around. Works great though :)
-
After TT conv. the main gear is about 2-3 mm away from lip on pinion.....one-way has always been installed wrong so my auto hub has always been upside down...is that the problem? I had to sand one of the delrin shims quite a bit to free up auto....may be too loose the other way around....how important is it for main gear to be flush with pinion lip ? If it's the auto hub...any advice on pressing out one-way? Thx
-
Both of mine also had the main gear sit 2-3mm lower after the torque tube install. I don't think it's anything to worry about. If the rest of your system is working OK, don't bother with trying to remove the one-way bearing.
-
Thanks steve 8)
-
Did you install both black delrin spacers between main gear and auto gear?
-
Mine is the same also 2 to 3 mm more and no issues.

Yes, both, although I had to sand one of them quite a bit...was super tight at first, thinking it was gear mesh at first - I loosened up all main shaft bearing block screws, screws for TT trans, that helped a little bit, tightened everything back up, sanded shim/checked, sanded/checked until it was just a little 'snug', knowing it might loosen up after a few flights - and now its about perfect, if anything I took a little bit too much off of the one shim, just slight play in main gear now, not as bad as before TT though...

Hi guys,
I'm putting together my E7 TT kit and the auto hub came pre-assembled to the spur gear hub. I'm trying to get them apart to check and make sure the 2 delrin shims are on top of the auto hub but cannot get them apart. Auto hub doesn't spin as free as it probably should and I was going to sand one of the shims a little like others have done. Any suggestions?
Did your auto hub and spur gear hub come in two pieces? Trying to figure out why mine came different from the way it looks in the instructions.
Thanks,
Luke
-
Got the two pieces apart. The auto hub sleeve that goes through the hub is a tight press fit into the spur gear hub on mine. Heated it up a little and spun them apart.
Thanks!
Luke

The mesh between my 12T and 54T spur gears is tight with no backlash at any position.
As the gears rotate there is a high spot in the mesh that is very tight and as such the main shaft cannot spin freely without force (It is not due to the delrin shims being too thick.) How much backlash do you guys have here?
Is there any adjustment built into the spur gear assembly or should i just let the gears wear down by flying?
