When updating a copter from OP 15.5.2 to LP 15.9, I have found a confusing setting. Revo is rotated 45° left from forward direction, so AttitudeSettings.BoardRotation.Yaw = 45, which is consistent with https://librepilot.atlassian.net/wiki/display/LPDOC/Revo+Attitude+Configuration#RevoAttitudeConfiguration-VirtualAttituderotation. Orientation of GPS v9 is the same as the Revo, so AuxMagSettings.Orientation should be 45 as well, right? But it was set to -45, and I must have been flying with that setting last year.

Those confusing settings seem to be correct, copter is indeed flying well with Revo orientation 45° and GPS orientation -45°, even though they are both facing 45° left.
