I was flying my P4 having a great time then all of a sudden it started climbing and I had no control. I hit return to home but nothing was happening.
It came back on its own after about 3 min I guess I was panicking.
I felt Helpless So I knew I looked like this.

If you playback the flight record and enable the RC sticks overlay, you can see what happened.
You may have gotten caught in an big updraft. And in your panic you may have enabled RTH but then  disabled it.
The key is "DONT PANIC", when you panic bad things happen.
I've been a private pilot for over 20 years and I believe a lot of the small plane crashes you hear about possibly could have been caused by the pilot panicking when something went wrong in the aircraft.
