i have a 5700kv mamba motor now. i want something better. i might agree the hobbywing motor may be as good as the mamba motor but it probably wont be better. i need something that has some really decent speed and torque without overheating. the mamba motor has everything down besides the heat. and i have TRIED EVER GEARING POSSIBLE. i have run from 12/90 to 18/88. it hits 180 degrees in 5 minutes regardless.
