Hello. I am a new member of this forum. I now have an AR 2 (Parrot) but am quite unhappy - specifically with the flight control using an iPad. I intend to buy a Phantom Vision 2 - possibly the Plus version. Is there anything I should do/read before I buy? I intend to buy from an authorized dealer even if the price may be a bit higher but an a little apprehensive about having to buy various add-ons ... I am on a Mac and have iPhones and iPads. Is the Plus version worth the price difference? Is there a way of flying using a GPS/map overlay? How big is the recording capacity? How safe is the "return home" facility (My AR lost connection and just flew away. Fortunately an honest person found it and after viewing the GPS flight recorder video, returned the drone) What OS is on Phantom and how accessible is it?
