After a couple of successful manual flights I decided to try a simple auto mission with my quadplane. It took off fine, and heading to waypoint one where it began to circle a few times and then headed off a random direction. It then turned around and came back to the way point where it began to circle again. On the second circle it banked much too far and stalled. I heard the vertical motors come on but it still rolled over and dropped out of the sky.
I noticed a lot of ‘compass variance’ errors. I’m confused by this as I only have one compass enabled. Also, when repairing the plane I noticed that if I turn the external compass the HUD in Mission Planner does not reflect any movement but if I turn the Pixhawk itself then it does. If I’m using the external compass then isn’t this wrong?
Here’s a link to the log from the flight. Any help would be most appreciated.
