Space is tight in my RC plane so I had to place my Pixhawk flight controller on its left side. I was able to orient my Ublox GPS + compass conventionally, meaning horizontally with the arrow pointing forward.
I believe that the board orientation must indicate an unconventional orientation by changing the AHRS parameter in mission planner.
But what do I do with the external compass orientation?
The problem I'm having is that the controls respond backward in stabilize, fly by wire A or B.
The controls respond correctly to transmitter input in manual.
Thank you for your help.
