Got my first drone yesterday - P3 Pro and did some nice beginner flights around a field. Message said to upgrade firmware so I did this morning to v1.2.6. Tried to fly it this afternoon...but said I need to calibrate it. OK. Got green lights on the first vertical axis but when turned camera down and turn 360 I get RED light and calibration fail. Tried again in middle of a field with NO metal or power lines in the area. Tried a few variations and the first rotation worked and the second always failed. It will not start now until I calibrate it. So I am stuck until DJI sends out another patch I guess. DO NOT upgrade to this crap firmware!! not happy!!!
