Hi, i just bought a xxx4 from a buddy and he did not have the manual, what is the suggested pinion for a 12 turn motor with a 90t spur?.

Thanks.

Id run a 20 pinion. if its too hot ( which its bound to be, I don't think ive even had a cool motor after a 4whl run) drop a tooth and keep going until its at a nice temp.

With a 10x1 D6 (timing close to 20 degrees, Putnam X brushes and purple springs) run a 92 spur with an 17/18 pinion. I would do the 18 tooth pinion.

thanks im running a D5 12x1, and the kid had a 124 tooth spur in it with like a 22 tooth pinion, i knew i needed to change that right away, and do they make a motor heatsink that will fit under the xxx4 body?


Thanks.

and is a xxx-s spur gear the same as the xxx-4? if not it has a blue spur gear in it does anyone know what tooth that is?, thanks.

Nope, they are different. The XXXS uses the spur gear and the drive pulley molded together (unless you get aftermarket gear adapters) and the XXX4 uses a spur gear with a slipperhub and drive pulley attaching to it. If it is a 64 pitch it would be a 128 tooth or if it is a 48 pitch it would be a 92 tooth spur.

As far as a heatsink goes, it isn't really necessary because of the lack of air flow. I think you could use the MF heatsink though if you wanted to use one. It covers up a small portion of the motor and you could probably clear the body.
