Sorry for all the questions guys. The P4 is new to me so Im learning all the quirks it has. I came over from the yuneec side so I now how to fly. Anyway. I flew this morning up on the golf course and had no strange issues come up except one and it only happened one time. While at hover about 60 feet up and in p mode with 16 satellites connected hands off the stick it rose up a good 20 feet and then came back down.Up down up down. Did it again and I brought it down by my stick. Did this a few times,then I continued to fly to see if it rose while flying. It did not. Wind was about 5 mph according to my hover app and KP is 2. Any ideas why it would go up by itself with no control on the sticks?
