I have had my P2 ZG for about 3 weeks and 4 flights. On my last flight I flew back close to were I took off and tested the RTH feature by turning the remote off. Well it failed. It was off target by about 10'. I tried turning remote back on to regain control. Lights went from yellow to green, but I didn't regain control. I ended up having to grab it in mid air and hold it and the motors shut down. Did I acquires sats before take off YES! Both S switch was forward on remote. Any idea of what happen? Should I have been able to regain control when I turned remote on? How do you regain control when your remote off? I then tried to take another flight and when I went up on the throttle and yaw the quad tilted forward causing blade to rub ground. Does this mean the compass need re-calibrated? Can you re-calibrated the P2 ZG anytime? Thanks in advance!
