I mounted the compass in the evening and to do so it required me to take out the main strutso that I could rivet it together.
The funny thing was that after I installed it I sat back to look at it and the compass balances out the markers on an angle. I thought that it was the install, however, when I ran up a level against it, the float was definitely out.
I hope that the calibration as part of flight testing will address this somehow, if not, I am sure no-one else will even notice. However, it does look wierd...
