Any idea why the main rotor blades don’t spin? I power up my tx then power up the 150 and the ESC beeps but the main blades won’t spin.. I know that it’s because the ESC won’t initialize but how do I fix this? I’ve tried adding negative subtrim to the throttle.. I’ve tried firing it up in normal mode and hold mode.. can’t figure it out and would like to fly the heli.. think it might be something in the iPhone app I’m lost..
