Long story short, i'm visiting the US and faith brought me here and I had my friend ordered me a P3P from DJI which will arrive on 22rd this month which leaves me roughly 2 weeks before I leave the US. Tbh I'm a total noob. I would love it if you guys can give me some advise or instructions to test the basic things about my P3P before i leave here and wont be able to return a failed product or do anything since where i live no one has it yet. I wont be able to fly it extensively since im very busy being a free tour guide for my non english speaking family. I only have like one or two hours max everyday to do something about it before sleep. And prolly only in my small hotel room in San Francisco. I dont have my computer with me except my iphone 6 with cellular so i dont think i can update firmware. What do i need to do to make sure dji shipped me an authentic one, a no problem P3P within my timeframe. Thanks alot guys.
