Spent another half day trying to calibrate the Compass and get the GPS to work, but I always had a problem getting the vertical calibrated because I always had to angle the arms.

So this evening I tested all the arms and the location of the IMU all the arms are in the correct position and so is the IMU however, now I think I know why I have been having problems calibrating my hexa.

Even though the IMU is located at the centre point and is located vertically in the axis, to calibrate the compass I have to move the hexa away from the vertical by about 5-10deg to get the LED to shine and to do the calibration, which makes it difficult and also I think it is what is puting the vertical circle off centre, which is what I think has been giving me the GPS problem.

Any solutions as how to rectify without stripping the IMU and shifting the electronics. I suppose I could always move the IMU so that it is facing 10deg the other way

Has anyone opened the IMU yet?

Any good advice is welcome
