Receiver Connection
A3 Mini supports PPM and multi-protocol digital serial receivers which allows you to connect the receiver to the gyro with one single wire on the slot [Serial RX]. Depending upon the receiver type selected, A3 Mini uses the preset channel assignment to recognize the channels from the receiver. Refer to the table below and check if your radio transmits the channels in the correct order. After each time you have changed the receiver type the current channel settings will be reset to the default. Choose "None" for those channels you do not use.
