I finally have my Skywalker X8 quadplane flying well. I’ve run in to an odd issue with RTL behavior. When I do a simple circuit and trip RTL when it’s far away and heading towards home it works just as expected. It’s amazing to watch.
However, I set up a couple of mapping survey grids with Mission Planner and at the end of these there is a RTL command. When that command executes at height the vertical motors come on, the plane sinks and then rolls over. It was easy to recover by switching to FBWA but I did two different grid surveys and it happened both times. There’s a log here if anyone can help out.
