I've repaired the Stable-Hover code, test build 8 is up for download along with some slightly adjusted dyn settings files.
Thanks Messyhead for finding the bug! We've got it nailed down now.
Thanks, I'll try the same steps again when I get a chance.
I was thinking about it yesterday, and wondered if my ini settings would have made a difference.
I'm using flight model 2, and engine realism set to 1.
My joystick has a split throttle, so one controls the engine throttle which is set to 100%, and the other is used to control the collective.
Without trying this out, I wondered if the altitude was increasing with stable hover as it was some how reading the engine power being set to 100%?
