I’m using ArduPlane 3.8.3 and a Navio2 flight controller.
I set up my Taranis (OpenTX 2.2.1) to send aileron commands to the right and left ailerons on channels 1 and 7 respectively. I programmed the transmitter to make more up aileron than down aileron as per the usual convention.
In ArduPlane I configured SERVO1_FUNCTION = 4 (aileron) and SERVO7_FUNCTION also as 4. When the ailerons are controlled through Arduplane and the FC, channels 1 and 7 travel the full throw in both directions. Even though the transmitter is sending differential inputs, the FC is outputting the maximum values in both directions.
I was able to reduce the downward throws by reducing the downward PWM values on both ailerons in the SERVO1_MIN/MAX and SERVO7_MIN/MAX parameters.
Is this the correct way to do this? It does not seem right and I am likely missing something.
Thanks,
Paul
