You should really start rethinking some of these issues. You're making it seem like this is all a joke and you're just shrugging off every suggestion. I think most people reading this thread have the same mindset that that's what you're doing with every single one of our posts.

Alternatively, the motors could be thrown in reverse. The problem with that though is that the leading edge of the props would become on the wrong side, greatly decreasing thrust.
