A friend is willing to give me a Phantom 3 for FREE! Sounds great but I have a Mavic Pro so don’t really need the P3 unless it is possible to put a P4 camera on it. What I need essentially is a 20 megapixel camera so I can do Drone base flights requiring 20 mega pixel minimum like construction site jobs. Can I put a P4 camera on a P3? Or is there another option to put a 20 megapixel camera on it? Thanks for help.
