So today is day two of owning my Phantom 3 Prof. Flew at least 8 times yesterday and 3-4 times this morning. Just went out in the desert on lunch break and had issues. I calibrated it prior to take off, did the auto takeoff. and immediately it would not hold its position and started to sway around. Luckily it was only 3' off the ground so I was able to catch it. Thought maybe the area had some magnetism issues so I drove another 5 miles away. Once again recalibrated to the new spot, Compass said it was normal and got the "Safe to Fly". Took off and exactly the same thing? Anybody have any thoughts? probably have no more than 2 hours flight time on it so far, all flawless flights! Thanks for your input!!!
