HELP, I posted this yesterday but go no response. I have been successfully flying DJI P2 fro a couple of months no problems. Yesterday went out and after normal preflight GPS lock etc. I powered up and all looked good until acceleration, then it lifted of the ground 2 feet and flew sideways into the bushes. I tried to regain control but it's responses were exaggerated. Later that day I went to a different location basically had the same result. loss of control, sideways track, over correction and slow sped crash. I updated all firmware. recalibrated RC and P2. Today I did another test with string attached and exact same thing happened. Anyone know what might be going on? Basically I am grounded until I can get control back. All crashes were relatively soft, although today I list half a prop. HELP
