Make a helicoptor in a plane simulator always seemed fun for me. This is my closest thing to that. The main components are the body of the helicoptor, and the rotor blade. In theory, the body should stay stationary as the blade spins around. The tail is only semi functional right now and it often brakes off. Never the less this is a fun thing to play around with. READ: To fly this helicoptor, you must first detach the first detacher followed by the second. This is to disconnect the rotor from the body. Also, it helps if you let that bar drop before speeding up the rotor to full speed (it will explode if that bar gets caught in the spinning rod). Thats pretty much it. Happy flying! Also, this design could use some athestic changes...
