The goggles thing has got me thinking....... If I buy a much longer lead, say a couple of metres, with which to connect the phone/tablet to the controller, then I can farm out a lot of the duties to my partner. With the goggles and controller, I can concentrate on flying smoothly, and getting the shot. Meanwhile, my partner, holding the phone/tablet, can select various modes, and make camera setting adjustments etc. This way, I won't keep on having to "let it hover" while I sort things out. I think the whole sequence will be a lot smoother. I wonder if there is a maximum lead length to avoid problems?
