I crashed my P3 Advanced into a tree the other day and since it just doesn't seem quite the same. First, it was a mild (stupid) crash, in fact, I'd say it was more of getting stuck in a tree than a crash. I was able to use an extension ladder and a pole and got it down gently. No damage was evident, just a little green stain on the blades from the leaves that cleaned up easily. Before this happened, the bird would return to home and land within a couple feet of the home point. Right away, I could tell that now it would return 10-15 feet away. I did an IMU calibration and then a gimbel calibration. Recalibrated the compass and tried again. I noticed that the IMU warmup seemed to take a bit longer than normal and I wondered if it was my imagination. Now, for the first time ever, it's drifting a bit while it hovers and the return to home was the worse ever. Landed about 20 feet away and almost landed on something. When I calibrated the IMU I used a piece of Styrofoam and leveled it up in the middle of my yard. Any advice?
