Had a hard landing today where the P2 flipped on its back, but the motors kept running. Was able to shut them off with the throttle. On examination noticed one of the antennas inside the quad was loose and out of position after removing the battery. Disassembles and corrected the antenna position. Went to fly again and the quad won't take off.

Using a tablet with Litchi, FPV is there, telemetry is there, can take photos or video. Just won't take off. Decided to launch from the button on the Litchi App and it rose, but didn't have any control. Quad hovered at about 10 ft with no problem. Shut down the transmitter and about 20 seconds later, the quad rose to the "Return To Home" altitude and landed. "WHEW".

Removed the top again and checked all connections. All are good.

In the house quad lights flash yellow slowly. (Ready to fly Non GPS).
Move the throttle stick left and right and the camera moves a little. (Always done this).
Attached the Quad to Phantom Assistant and all says good.
I use CSC to launch normally. (Left stick bottom right, right stick bottom left)
When the drone was hovering, I had no control.

So I'm lost now. Any ideas would be appreciated.
