While my 3rd flight was great, I've noticed that my FW is like 1.11 or something low like that so I'm pretty sure I gotta update it. My question is if I have a spare micro SD card, should I just format that and use it or put it on the card that came with it? I've never done this yet and I wanna know which is easier. The last thing I wanna do is brick my P3A.
