this ESC work great with my tamiya M06 car . it really small and it fit perfect on it. you can't really put on a fan on it . the wire for the motor are little short so I had to make longer one to reach my motor no big deal. if you brake to hard with esc it will make my M06 spin side way . like the fact that you can use lipo or ni-mh battery and give good power to the motor I am running a Orion 23 turn brush motor. my futaba 4pl transmitter i can set the delay for the reverse so it don't back up really fast when you stop with is nice.
