What's up there, Has anyone been able to crack the 500m altitude limit yet? I don't mean any weird RTH gimmick, but a real solution via software or some kind of firmware hack. I have the P2V+ and I'm not trading it away until it's confirmed I can fly as high as I want. I'm also willing to pay good money for a solution, be it an Android app or whatever else. Completely idiotic these kinds of restrictions.
