I work with super cars for a living and want to film some of them for private footage etc and so I decided to buy the Phantom Vision Plus which looked like the best buy on the market for what I wanted. When I got it it took a bit of getting used too and I've only managed a few flights so far, practicing in the garden etc but when I first had it, it tried to fly in the same area which was nice and safe and now it pitches front to back, side to side. I have tried the carbon rotors which don't seem too good so will be changing back to the plastic OEM ones. Also, I lose signal at around 600-1000ft I don't think I need to fly further but is there an option to do this whilst still being safe and easy to fly ? Any help received with thanks.
