Last weekend I pushed all of the current updates to my P2V. Took her outside to my usual practice field and flew two full batteries in GPS and a little in ATT mode. Had no issues at all. Then I loaded her up, got on a plane and flew to South Carolina(about 4 states away). I was near the coast and a large industrial park. As soon as I started the P2V my phone app demanded a compass calibration. I did the dance. I originally tried to take off on a large concrete slab but was not able to get any satellites at all while on this slab. So I moved to grassy clearing a few hundred feet away. I got 7 satellites and lock looked good. I put her in the air about 10 feet for pre-flight check, immediately she began to drift to the right and upward gaining altitude very quickly towards some trees. I fought her down to land, it wasn't pretty but not too hard. Tipped over and broke two blades. I replaced the blades and did the dance again... exact same results(two more blades down). A little later I went to a completely different location and took off in ATT, she was stable aside from wind drift(but manageable). I put her up in the air about 100 feet and switched to GPS, had about 9 satellites. Seemed to hold okay, but appeared to be making very strong adjustments with hands off the controls. Had to land in ATT because GPS did not feel right. I am back home now, I did an advanced re-calibration in assistant and did the dance. I did a test flight here where I have in the past flown several times without issue and am seeing the same upward drift now. Something appears off with GPS but basic calibration and advanced in assistant don't seem to help. I am at a loss. Help would be greatly appreciated.
