Got my bird back the other day after warranty work was done to it. Work was done to my satisfaction I am back in the air. What I am noticing is on the remote when I'm ready for takeoff I can't use the A/F modes or are those modes only used once you are in the air? Reason I'm asking is I've never used those two modes at all, I always fly in GPS mode but I want to be a little bit more adventurous and see the waypoints/follow me mode and try some of the other features on this advanced I have.
