Brown-out with more than 2 servos
I have had two of these 12 amp ESC's. I have used them on two different planes that are 4 channels (4 servos). Both planes would have brown-outs and crash. If I change the planes to 3 channel (no aileron servos), the brown-outs would not occur. Since I wanted to use ailerons, I had to buy a separate BEC to resolve the brown-outs. This is a disappointment for the mini trainer which I prefer as a 4 channel plane.
