If I pick a POI like a large building etc. which, while circling could result in loss of signal will the copter RTH? If that is the case then one would not be able to use POI unless the copter is well above the subject. I have a stack (300+feet) in our local park with stairs going to about 200 feet that I would like to film. Looking forward to the zoom in the cameras in the future. Also, what rate would you suggest for circling?
