I've had my summit running on 2s for some time now with no probs but today i put in a 3s lipo and had a little fun. It ran fine for about 10min max. then dropped power and after putting in a 2s it just stutters in forward mode and has no reverse at all. I tried reprogramming and also unplugging the steering servo, the motor is pulled off and spins forward but not in reverse. I'm not sure what else i can try??? I thought these esc can handle a 3s. am i better off with a different speed controller or try get this one repaired?
