Hi,
Does the DIY Drones magnetometer when incorporated with APM 2.XX actually assist in the navigation equations during low ground speed operations or is it strictly used for GCS/OSD mag heading displays.
I am not the best at interpreting code, other

I am a final year masters student studying Aerospace Systems Engineering the the University of the West of England. I am currently using the UDB V3 for my final year thesis in order to develop a flight controller for a small UAV.
I do not know C,
In the latest MatrixPilot source code, in the file rollCntrl.c , at around line 125, there's this function call:
rollAccum._.W1 = determine_navigation_deflection( 'r' ) ;
But when I look inside the implementation of determine_navigation_deflection, I

Normally if a servo is going in the wrote direction, you would just reverse the servo on the radio.
Because the servo is being controlled by the APM, wh
