I was hoping this firmware upgrade would make the tilt control better but instead, my gopro is always facing a little down, and when i adjust the pitch to the bottom, it actually looks behind the P2. The real issue comes when I turn the quad. I read of it described as "horizon drift", but its really bad! I turn left, the gimbal starts rolling right, and not just a little. When watching FPV, it looks like the p2 is about to flip and fall out of the sky. Check it out: http://youtu.be/-QLHgGRxYuM I have tried using the RC assistant software and calibrating, then using the P2 assistant software to calibrate as well. No luck. I dont know if im doing the calibrations wrong or what, but nothing I seem to do seems to make this any better. Does anyone know of a way to revert back to old firmware, or has anyone else experienced anything like this? For filming use, I feel like my P2 is now useless. I refuse to waste my time contacting my dealer (dronefly.com) because I already know what they will do, charge me $99 + cost for a new H3-2D. F- that.
