Ok I just bought the hacker b20-26s and I am not about to go modifying it. I just need a battery that will give the best performance without burning up the motor. How about the 2s2p Etecs? or what if I use my current 3s1p kokam with a 10x4.7 prop instead? I tried to retard the timing as much as possible in the programing of my cc pheonix 25 controller but the motor is still getting pretty darn hot after a run.
