Hi!
in RTL the plane looses altitude. It first moves up to some altitude close to the defined (90m) and then slowly drops with each circle. Throttle stays at 75% as set. I have to switch to manual to prevent a crash.
Any idea? I have the feeling that the messages from the internal barometer and external GPS don't fit.
Thanks!
Chris

My setup:

APM ArduPilot Mega 2.6 - vertical
