I'm baffled. Spent at least 20 minutes looking online and can't find an answer. What is the model number of the Phantom 4 Pro version 2? I'm talking about what you'd find on the sticker in the battery compartment. I can find the P4 is WM330A, P4P is WM332A, P4Advanced is WM332A. I've even tried randomly googling model numbers in that string, no luck. Going to look at a used P4P and I thought checking the model number sticker would be the quickest way to inspect the bird and tell version 1 from 2. Thanks!
