The Osprey may look good on paper but in practice it's a disaster. The Marines have already given up on it. I have no idea why this stupid project won't just die.
The immense angular momentum in the props means any engine problem no matter how small puts in down. The props have to be perfectly synchronized at all times. If you think an RPG is deadly to a standard copter, imagine a hit on this thing. It's a death trap.
The way to get troops into battle is with large traditional 2-rotor copters with A-10 and Puff support for suppressing fire. So much for complimenting the Pentagon. What, did the Navy get lonely or something?
