We are a US corporation that bought a P3 advanced. We want to fly it for studying the feasiblity of doing commercial things with it. Basically, it is for R&D (and fun!) but we won't be charging anyone anywhere for it. I'm assuming I just have to register it with FAA and that is it...? I have: 8050-1 8050-88 Print out from DJI.com $5 check This should be enough for us to fly within the current rules, correct?
