Have you tried casting the 520 in manual mode to see if that gets your desired path. Altitude and last heading should still be quite stable. Have not performed myself.Thanks for the input so far guys. I have another question on the controls so thought I'd post it here rather than start another thread...
Does the H520 have a 'cruise control'? And is this the same as a course lock? It would be great if I could get the drone moving in a smooth, straight line and just concentrate on controlling the camera (and maybe altitude).
I had the idea of using the trim controls to do this but not sure it will get to the desired speed.
