I've seen your clip and the problem you have with the props. But have you given any thought to flying slower so the pitch isn't that great and speeding up footage in post? Which editing software do you have?
That's a workaround. The problem is its just that, a workaround. Sped up footage can often look sped up. Especially with a phantom. I ain't makin movies so I'll live with it. But if someone had a viable solution for a Phantom 2 that would keep the props out of the shot, I'd probably consider it.
DJI's solution seems to be the Inspire 1. Not sure I'm ready to drop that kind of coin just yet.
