Hi, Received my P2 + Zenmuse H3-3D today. All set up okay, and did a quick test flight. I couldn't get it to just hover when I took my hands off the controls. It kept drifting in an arc, and at one point just lost power. The battery was 100% at the start, and about 35% when I finally stopped. I'll need to fly it again to see if the drift is always in the same direction. I managed a couple of crashes. No obvious damage other than scuffs (no chips or dents) to the props. I updated the firmware before the first flight, and completed the compass calibration. Has anyone seen anything like this before? Any idea what I should do? Thanks Darren.
