My personal view is RC 3 is rubbish compared to RC 2. Too many glitches and the programming is very sloppy. Their is nothing worse than seeing the trees and the aqueduct appear when you fly over it. They are either there or they aren’t. As I’m using one of the most powerful iPads on the market it is a surprise to me that my iPad doesn’t have the processing power to render the landscape properly and that’s because theyve programmed the program beyond the capacity of the latest technologies or their are still too many glitches. The other problem is that some of the aircraft have a habit of going into uncontrollable dives which make no aerodynamic sense, clearly their is a problem with the aerodynamic criteria. Overall stick with RC2 dont waste your money. RC 3. RC2 is much better with more aircraft and landscapes.
