I bought a Vision plus because my Vision crashed and just received my rebuilt Vision today. IT took 6 weeks but it was a firmware problem and DJI totally rebuilt it from being busted into 100 pieces. I didnt expect them to do much about it so I was surprised when they said they had shipped it. My battery was busted too and they didnt replace that but I guess I should be happy they did anything. Anyway, can I use same firmware to update both? What about the app? will I need to bind my phone every time I switch from one to another? I plan on selling it but I do want to play around with it first to see how it flys.
