Howdy all,

I'm building my 1st RC car, and I've run into a snag. The collet which came with the NTC3 kit fits perfectly into the flywheel, but has approx. 1/64 play on the shaft of the Picco motor. The collet that came with the pico motor is not an exact fit to the flywheel, but seems to be ok when I crank it down, the only problem is that it is approx. 1/32 too deep, so that when I get it all together the gears will not mesh properly, they are off by that 1/32. So, do I need to go find a Collet that is the perfect fit(and if so can you give me a good place to find collets), or should I just shave down the collet that came with the Picco and make that one work?

Thanks for hellping the n00bie

I also had problems with the Flywheel and Picco collet when mounting on my GT.

Use the collet that matches the inside of the flywheel. Carefully file/grind some of the excess on the Engine side to get the correct gear spacing. You can also leave out shaft the spacer(s) on the crank to adjust the distance.
