Really two questions... 1) Just got my new P3A via UPS today. I've had to shelf all my P2+V3 stuff (Batteries, chargers, parts/pieces). When I look at the props I had that came with the P2+V3, they look identical to the ones that came with the P3A. Anyone know of any difference? 2) So, brand new P3A. Took it out this evening to re-introduce myself to flying again. Been almost three months waiting for my replacement. Lots of new stuff to learn. With that in mind, the more I read, the more hesitant I am to update. The DJI Go app keeps barking that it wants an update. What are the +/- for updating the P3A?
