I'm having trouble with Home Lock not working in GPS mode and would like to hear some things I might check. I'm getting the green only flashing light indicating adequate number of satellites after going thru the startup sequence with the Phantom. I have the left switch in Home Lock and the right switch in GPS at takeoff but get no home lock even after flying outside of the 10m "circle". There is a statement in the manual that Home Lock shouldn't be engaged until after flying outside the 10m circle but that method doesn't seem to work either. The craft does hover and respond well when releasing the sticks and flies well as it would with Home Lock switch off. Can you guys help me on this? Edit: Should mention that I am doing a successful compass calibration also.
