I catch my P4 by hand all the time, I simply however it had about shoulder level reach underneath grab a landing gear leg and then hold the throttle lever all the way down till the motors quit spinning never had a problem.
After many many hours of flying my P4 finally developed some cracks in the vent openings on the bottoms of the arms. I used superglue and fine fiberglass mesh over the cracks work fine haven't had any more problems
I fly in my living room every once in a while. The drone will pick up 10 or more satellites inside the house it just takes a little while. Just be careful if you fly in vision mode.
