I've recently changed the stock landing gear for the extended landing gear and mounted my compass on the vertical section of the right rear leg far away from anything else. The receiver antennas are on the front right and rear left legs. I notice in the Phantom RC Assistant software there is provision to manually add the X, Y and Z distances for the compass position. As the compass is now approximately 30mm below and 30mm further away to the side of where it was originally mounted should i get a ruler out and enter the new values? I'm not keen on waiting for a crash to discover the correct procedure. Thanks in anticipation of genius input.
