Yeah... the stuttering is also has to do with it not being sensored too... little electrical glitches and a bunch of power... no way to really stop it, can just add a sensored motor to the 120a in the future... youll be set!
Gonna go with the 120a esc from hobbywing too!
The idea of 4s in the future sounds tempting! The idea of a sensored motor sounds good too....
Couldnt do it with a sidwinder 3
