***brushless Motor Overheat***

The motor was spinning way out of its efficiency range probably. Too numerically high of a final drive ratio, and it doesn't put enough load on the motor. Still haven't figured out why brushless motors like a certain amount of load to run cool...

There's a general rule of thumb to not overgear, but also not to undergear a motor.

ok thanks...

guys take a look on this motor can it is useless to put a heatsink on this ?
