Hi,
I have a flying wing with PixHawk "mostly" working. Sometimes it seems to have a problem with altitude when in auto mode and flying a waypoint mission. Here's what it does:
Fly RTL mode OK
Fly manual mode OK
Switch to Auto with preprogramed waypoint mission loaded. Plane accelerates and descends while heading for waypoint 1. Can't react fast enough to switch back to manual and climb. Plane hits dirt.
It's done this behavior a couple of times. One of the times I changed all my waypoint altitudes to 200M. Then the plane flew fine, way up there. Log attached. Any ideas?
Thanks!
Brian

My friend, forget Pixhawk for everything. Try in your jet model, Navio2+raspberry pi. Did work Very well for my jet.

In my case above it was a poorly trimmed airplane. As an old RC guy who learned on sailplanes I always trim so the nose slightly falls. I fly with back pressure on the stick. Not a good idea with a Pixhawk. Trim your plane in Manual mode so it flies perfectly level. Then you must recalibrate the radio using Mission Planner. Your plane should now stay level as it transitions between flight modes.
