Crash recovery

I powered the hooked the Phantom up to my computer, powered the motors and pushed the direction stick forward. The Naza said that I was doing something but the motors did not respond. I am going to need to tear the entire thing apart to diagnose the issue. I am starting to think that the Phantom is more trouble than it is worth. It might be better to convert the whole thing to an F450 frame. I would still keep most of the hardware but it would be far easier to deal with these sorts of issues.
