I am using APM 2.6 electronics and the tail rotor is a direct drive brushless. When I plug in the battery, the tail rotor ESC will start spinning before I’ve armed the helicopter, but the main rotor doesn’t spin until after it is armed.
Thanks, I’m using RC channel 4 for output for the tail rotor ESC, I don’t see a RC4_FUNCTION
parameter to set passthrough to false, they seem to be for RC channels 5 and higher only I think…
