It saves the pwm to ppm converter and now i wait for the motor. next try
Seeing you are an electrical wizard, when your brushless motor is running what kind of voltage do you get to the tail motor. Im not sure if this would be an issue, but if the system voltage was getting low could there be an amperage increase causing problems with the tail motor. I have no idea what the correlation is in a variable speed brush motor between Volt/Amp.
