I have been wanting to circle a fixed point, like a house, keeping it centered in the frame. My first attempt was done by putting my FC40 in Home Lock and then just moving the right stick left or right. It sends the quad into a circle around the HOme Point, but I have to keep making adjustments to keep the object centered. I think I have come up with a better way of doing it. I set the distance limit to 50 yards. I move out to that distance until it can go no further. Then I turn the quad around and pull the stick back and to the left or right. This forces the quad to stay 50 yards away from the Home Point, which causes it to go in a circle. In what little testing I have done, it seems to keep the Home Point centered better with fewer adjustments. The other way to do it is use method one with a mod to the transmitter to add a slow motion yaw. Also, for the life of me, I can't reset the Home Point while in flight (hovering). I'd be interested in hearing from other people that try this.
