I have tried searching, but cannot find an answer to this. I have a Phantom 2 Vision+. After landing, holding the left stick down for a few seconds kills the motors. This is documented in the manual. My question is: what happens if I hold the left stick down while in flight? For example, if I am up 400', and want to descend quickly, can I hold the stick down at max descent rate, or, will I kill the motor after three seconds? I assume there is something in the software that says that as long as it is descending, holding the stick at max descent works, and holding it there while it is motionless initiates the shutdown. But, without finding it in the documentation, I figured I'd ask the experts. Thanks for any input anyone has.
