I'm thinking of maybe buying a Phantom 3 professional. I have read that you can get upgrade engines and reinforced shell to prevent cracks. But how do I know that I get the later model with this? P2 called the later version V.2 If I buy a p3p I would like to get that upgraded version. What tablet/ipad would you recommend to use as screen for the p3p? I was thinking of use it only to the p3p so it doesn't have to be a expensive thing. Is it better to get a ipad since Im using Mac computer?
