Re: Gas R/C car
What exactly are you trying to do? Take a T-Maxx and make it have a bigger chassis with a bigger engine? What is the end goal of this project?

If you are looking at a wheedwhacker engine, I'd suggest you look at a chainsaw one instead. Unlike wheedwhacker engines, they usually have the pull start in the rear so it will be easier for you to adapt something to the shaft in the front. For a centrifugal clutch, I know most gas chainsaws have one, but other than that I'm not sure about any details since I don't have a gas chainsaw. It is possible (not certain, but you could try) a gokart style centrifugal clutch would work if you made a properly sized keyed shaft (5/8" or 3/4") to adapt to the engine.

These wheedwhacker and chainsaw engines can usually get up to around 7-8K rpm (provided they are the 2-strokers).
