VTOL Rudder Reverse Movement

Hello All,

I have a problem with rudder movement for Generic Quadplane VTOL.
In the Fixed Wing mode, the rudder is moved reversely with transmitter rudder stick movement.
Does anyone know how to reverse the rudder movement without changing hardwares?
I was thinking about changing settings in my transmitter side, but that affects not only the settings for fixed wing mode but also the multicopter mode that I don’t want to reverse the settings. So, it doesn’t work.

Setting the PWM_AUX_REV3 param to 1 should do the trick.

Thank you very much for your response. I appreciate it.
