Brushless Truggy Part 2

[Shark413]

Ok after reading some of the other post on this site related to the Tekno clutch I decided to pull the trigger and I ordered one on Monday. It arrived today and I spent most of the night fabricating a new motor mount. I started by raising the center diff to give me more room, I then mounted the motor, attached the Tekno clutch (currently I am using MIP shoes) with a traxxas 15T bell. I also had to move the brake servo slightly to clear the bell. I hooked everything up and ran it on the bench just to see if it worked. The clutch acts just like a nitro clutch. When I gave it throttle the motor would spin but there was a slight lag before the bell would move, then as the speed picked up the motor spun the bell/spur at full power. This is just what I was looking for. Tomorrow I will put some street tires on and give it run in the yard to see how it performs under a load.


Here is the new motor mount next to a RC-Monster mount and my originally mount. The new mount has been extended to provide more support.

Update:

I was worried that the stock Revo 2 shoe clutch wouldn't be able to handle the weight of my truggy. So I ordered a special 3 shoe flywheel which arrived yesterday. So today I turned it down so it was even with the bell. This flywheel is the special NewEra flywheel made for the Revo. A little background, I have the Tekno adpater that allows you to use a standard Revo flywheel/bell, which uses two shoes and is smaller than a 1/8 scale bell. I wanted to use a heavy duty 3 shoe fullsized 1/8 scale flywheel/bell which is taller and normally wouldn't fit (too long front to back). The flywheel I got is specially made to be much thinner and allows a full size 1/8 bell in the same space as the stock Revo flywheel/bell.

I hooked it up with alloy shoes with no springs (so it engages sooner) and hooked it up. I took it for a spin and the clutch works great, it spools up smoothly before it engages, but once it engages it is very strong. Unfortunetly it was a little too strong and the combination of sticky tires, super powerful motor, wornout diffs and 100% traction blew out the rear diff. The diffs on this project have a lot of milage on them and were in need of a rebuild anyway. I spent the remander of the afternoon rebuilding both diffs. I hooked everything back up and ran it on workbench and it seemed to be working perfectly (too dark to run on the street). Off to the track tomorrow to see how it performs.

That is nifty, any chance of a link to the flywheel? I like the idea, as I had wanted to use a clutch setup in my 2 speed yusa, and modded a 4tec 2 speed bell to work. The newera flywheel sounds like a much better idea.

Is this it? http://www.neweramodels.com/item.cgi...=&part_id=2643
