On several recent nadir flights (2D photogrammetry selected), about 5% of the P4-RTK's images were oblique, rather than nadir, so they were useless for the mission.  Has anyone else seen that behavior, and any insight as to why, or how to eliminate it?

im sure you tilt the gimbal during the mission with your left hand (gimbal dial)... it's not locked

Thank you for that idea, Guille.  There was no manual intervention on this flight, and in each case (three times each across four identical 9-minute flights), the Phantom took two oblique images, then went back to nadir images.  And in each of these 12 cases, the oblique images were in about the same location.  They seemed like they might be right around the end of one flight line and beginning of the next; i.e. a turnaround point.  But thank you again for your thoughts and ideas.

Maybe it is  "Elevation Optimization" enabled? pag. 28 manual.

Thank you, Guille.  I just rechecked the images, and that's exactly what it was!  Thanks for your insight!
