Hey, Thanks for all of the help so far. Reading these threads have saved me a ton of time. I couldn't find an answer to my exact problem, though. The gimbal on my P3P points slightly to the left. This wouldn't be a big deal, but in flight it catches the left arm and landing gear pretty often - even on gentle turns - and ruins any video. I've done a full IMU calibration followed by the gimbal calibration to no avail. The horizon is level, but it still points to the left. Is there anyway to tell it to look a few degrees to the right at all times or something along those lines? I have a picture showing how much farther left it looks than right (this is with the 15 degree extension turned on and pointed 100% up to illustrate the issue) but I can't get it to upload from work. You can clearly see the left arm and all 4 screw housings underneath (with the 2 leftmost housings about 80% in the shot). The right arm is not in the picture at all. Any help is appreciated, thanks!
