I'm looking for an advice what should be tuned differently in my otherwise very nicely flying copter. It's very stable, vibrations are well within recommended limits - when recording video with GoPro there is no jello at all. However when I switch from stabilize mode to AltHold and fly with just a bit more dynamics sooner or later the copter shoots up. I mean the throttle is out of sudden set to maximum value and copter ascends rapidly. The only reliable way how to prevent it from flying to completely insane height is to switch back to Stabilize and descend manually.
Any ideas what should I change here?
