in my tc3 i use a element 19t mod and i love the acceleration but the top end is a little slow, and at the end of a run my motor is not to hot so do i add a tooth on the pinnon or take one out?

davepull

if you want more top end usually go up a tooth or more.

are you running it on a track???

kh15

not a good track just a parking lot with some cones lol

then I would go up a tooth and keep an eye on the temp have fun

Might be worth getting the Reedy heatsink w/ fan to cool your motor.

If your motor dont have ball bearings, I would install some. More speed and lower temperature.
