My Q500 will not stop descent and return to hover when switched from home back to Angle every time even with good GPS satellite lock. Yesterday it descended too fast and I switched to Angle with full up on left stick and it continued to the ground and bounced hard. No damage. Went home and updated both bird and transmitter. GUI also had no problems indicated with motors, etc. Battery was at 11.2v. Anybody have any ideas or similar trouble. Also, I have not flown since updates were done due to windy conditions. This was a new bird March 1st this year.
