I did this a good five or six years years ago, THEN I saw AVATAR!!! arghhhhhh!!! although mind you, the idea of an enclosed rotor on VTOL swivels goes back to the 1960's, BUT STILL, damn youuuuuuuu James Cameron for putting it out first!!! heheheheh ... I am still happy with the design though.... it's kinda sorta loosely based on a Harrier Jet and a Navy rescue helicopter.... basically, I just wanted something that looked very muscular, and could carry troops and equipment to the battlefield without breaking a sweat!
