My Phantom 2 had an altercation with a tree and dropped about 20 feet to the ground. Not that big a deal, but it did bend the gimbal mounting plate. I replaced the mounting plate and now everything is nicely aligned again, except the gimbal appears to have developed a 10 degree downward bias. Here’s how it looks fully up and fully down: You can see that the main gimbal frame is nicely upright but the gimbal is simply biased down. Apart from that it’s working perfectly – no problems at all. Any ideas how to fix this? The IMU is calibrated, X1 is calibrated, and the servo value goes from 1000 to -1000 as expected. As I said, everything seems perfect except for the fact that its level reference seems to be off but I don’t know where it gets that.
