Does anybody know about how much distance the P3A is supposed to cover while auto-braking from full speed? I was flying yesterday on a perfectly calm day (wind @ 0 MPH) well away from any interference with the drone at relatively close range and noticed really erratic braking behavior. A couple of times it seemed like it was coming to a stop much more aggressively than usual, and a couple of times it coasted for an alarmingly long distance before coming to a stop.
On my last flight last night I actually had my first crash when it went coasting in to a tree. It was in P-GPS mode the whole time (confirmed looking at the flight record that it was not in Atti) and if I'm reading correctly off the flight record it actually coasted about 125 feet after I released the forward throttle before it hit the tree. I actually went full reverse for the last 40 feet and it just kept coasting. Luckily the damage seems fairly minimal (thought I haven't taken it back up in the air yet) - the shell popped open a bit on one arm and won't fully snap back closed, one of the sonar sensors has the aluminum ring around the outside bent in a bit (not sure if that hampers functionality), and there's just a bit of scuffing on the gimbal, shell, and battery. All in all it could have been much worse but I've never seen my drone take so long to come to a stop, especially with giving a full reverse throttle for the last 40 feet.
Has anybody else experienced anything like this? I'm wondering if this is a scenario where DJI might foot the tab for repairs since the auto-braking didn't seem to work. I know others have gotten crash repairs under warranty when the flight record showed the equipment didn't act as it was designed to, but not sure how outside of the normal stopping distance this was.
Edited: Note that I've never changed any of the auto braking settings - all of those settings should still be at factory defaults.
