I am testing a new power system based on an AXI5320/28 and an el-cheapo 100 amp ESC (by himodel in China) From time to time if I let the motor stop, it would not pickup RPM but sort of misfire and speed up very slowly. The cure is to cycle the throttle from idle to full speed a couple of times and then transition goes back to normal. Any clue what could be wrong? I can change the timing of the ESC from 0 to 30deg but it only adds more RPM/amps at full throttle, I also tried the acceleration settings, throttle curve, timing monitor, and PWM frequency...
