It is a tri-pod, so it can assume any angle. It has to be installed on the same angle as the D10-A. Also, I have seen no issues with it as the magnetic compass always seems to be accurate. I will know better when I get my OAT installed so it can calculate wind speed and direction. Then I can compare it to the GPS heading.
PS: The networked units are great. Being able to get any page from either of them on both of them is fantastic. Now, with my IFLY720, I should be set.

I did not see any means for moving and adjusting the magnetic sensor in azimuth.
