I have experienced the toilet bowl effect and received compass error message 9 mins into the flight while hovering 6 feet off the ground in my backyard. Also, motors became extremely hot. When I tried to calibrate the compass, I kept getting the white light indicating failed calibration. It took 6 attempts before it calibrated successfully. WTH. Ive never had trouble calibrating the compass before. While others are happy with the new firmware, it introduced issues for me. Prior to updating to 2.25, my H flew just fine. Dang, I should have never upgraded. Yuneec should give us the ability to roll back to previous firmware.
Still getting camera feed failure with legs up on Eu firmware. 4 flights, no compass errors but rssi occasionally in red zone using Helmut Elsner's programme. Flies very well, love the awesome ability to control direction and speed using the trim and video significantly improved.
