Sounds like some good info there.

I have modded a 4tec clutch bell and will run it with a your clutch adapter in my 2 speed yusa rally (like an inferno gt). It is 1/8 scale and geared pretty high so wee will see how it runs. I am using an integy 3 shoe al clutch and we will see how it does. I had to turn the flywheel down to fit, but the integy flywheel is larger than a stock or lightweight traxxas. Motor is a 2600kv aveox and I am using a quark 125 airmaster esc. 4s lipo to start and I may step up to 5s for speed runs. 4s should do 70mph in second, so I may not bother with 5s!
