Warning BUG in ACRO Mode in Arducopter 2.9.1

[Jumpy07]

There is a bug that if you switch out of ACRO while upside down your throttle will remain at 130!
If you do use any other mode to recover the copter will rotate back to horizontal but you will need to switch back to flip to get throttle control back.
There is a section of the code that reduces the throttle to minimum as you go inverted is based on a variable that is updated only when in ACRO mode. This means that if you switch out of ACRO mode while inverted the throttle will be stuck at minimum throttle.
