So I shipped my P3P to Maine and back and the gimbal lock had fallen off during the trip up there. I noticed it was off axis and tried an IMU and Gimbal Calibration (on a level surface of course), but I still have the slight cantering in my photos with the horizon. You can even see that it's off when it's powered up and connected sitting on the table. I tie wrapped the gimbal lock on for the return trip, (which I would recommend everyone do, just keep some tie wraps and a pair of cutters in your kit). Anyways, I'm going to try it again now that I'm home and have some time, but are there any other suggestions that may help level out my gimbal? I will update after I calibrate again, and post some photos.
