Favorite tip:
Don't Panic! Or if you prefer, "keep calm, and drone on!" Lol.
Seriously though, take it slow, if something unexpected happens, release the sticks and think then react.
If you have warranty, worse thing that can go wrong is major hardware failure, in which case 50% of the time a knee-jerk reaction may make it worse. Taking hands off stick ensures no pilot error, and at LEAST ensures warranty coverage. But in most cases save for a catastrophic failure, taking hands off stick will result in a safe hover, you should have at least a couple seconds to think then react calmly. Don't over react with wild stick movements, steady measured movements.
I might be new, but from watching videos of crashes and reading horror stories, aside from the blatantly unavoidable hardware failures, 90% of crashes seem to be pilot error, most of the time someone who panics and reacts without thinking and causes a crash.
Staying calm and in control, is likely the #1 way to save more drones above all else. (IMHO)
