Pixhawk Servo Reversal Fixed Wing

Posted by Samuel Rosenstein on November 8, 2014 at 5:34pm

Hey guys,

I'm currently running my Pixhawk with the PX4 autopilot project firmware (found here: https://github.com/PX4/Firmware), also the firmware that is loaded through QGroundControl. I need to reverse the servo output for my ailerons, and I can't find the parameter to do so. Do other people use this firmware instead of the ArduPlane firmware? Does anyone know how to do reverse servos in this firmware? 

Thanks in advance,

Sam

    You can do this on your transmitter or in the advanced parameter screen. Transmitter. Is the easiest.

      The reversal is when I am trying to use FW mode or AUTO mode. The transmitter control is correct. 

      For example, when I roll the plane left, then left aileron raises.

          Thanks, I needed to change to ArduPlane to get this feature. However, now that I've changed to AruPilot the Servo Reversal function checkbox causes the servos to no longer work. For example, if the "servo reversal" checkbox is checked in APM Planner 2, and I uncheck it, whichever servo(s) I uncheck no longer function in any stabilized mode.
