Yesterday I sent my phantom 2v+ higher and further away than I've previously dared, and I invoked RTH twice on the S1 switch to get me out of trouble - I made sure I had good GPS reception and a home point set. It really is a great feature for getting you out of trouble. It was only afterwards that it occurred to me - what if my phantom had lost the GPS signal in this scenario? I could still see the unit but working out which direction it was pointing at that distance was pure guesswork as I'd also lost video reception - in fact, the DJI app crashed several times on me during various flights. An errant gust of wind at that height would be a disaster in ATTI mode. Is there a fool-proof way of knowing which way your phantom is facing? Should I invest in some sort of ultra-bright LED to stick onto the front? or should I bring binoculars? It's easy to see how things can go pear shaped quite quickly. I am seriously considering investing in one of those stage 1 booster kits to firm up the video reception.
