I have connected my receiver to the pixmini via a ppm encoder. I have a power source going to the PM rail and also have another battery pack going into one of the main out rails. When i connect the servos. it responds by twitching once but seems the servos arent recieving signals from the ppm encoder to the main out. So how do i connect the ppm encoder to the autopilot and make sure there is signal being received by the main out rails please. i have connected the ppm encoder to the ADC 1/2 but is this wrong? Thank you.
