This was just a test and the speed control reached 175F and the motor reached 130F and the battery came off at 109F, indicating the truck was over geared. I know the 7700 wont last in the revo but the Neu motor will solve that issue. Is the motor I listed OK for the revo? Based on that test with the 7700, 4s will be just too much power for racing but if you need 4s for effeciency, I will just have to tune every thing down and gear it low. Thanks for the help.

4S-5S-6S and motor with low KV (from 2200 to 1700) are for power and efficiency.
7700 Is for 1/10 1/18 vehicles. With more volts you'll run cooler, longer, and with much power.
