Gears
 

I have a Speed Gems II motor and it has a 24 turn gear on it and hte othjer ger is I think a 71 tooth what size should I put on htere for more speed?

To get more top speed, fit a larger pinion or a smaller spur.

To get more acceleration, fit a smaller pinion or a larger spur.

Be wary of gearing too high as you may overheat the motor and spped controller.
