Left Stick Down to turn off, mid flight

[Mark The Droner]

If your motors stopped and your craft dropped from the sky at 12 feet up with the right stick centered, you have a battery problem.

 

[Dirty Bird]

Nope. Bad battery issue maybe but in flight you can hold the left stick full down all day & the motors keep right on running.

You say that but it's just happened to me at 12ft up
