Driving Helicopter

This is a very crude, outline concept of a helicopter that can also be driven on the road. There are 4 rotors (2 clockwise and 2 anticlockwise) which can be folded down for driving. It should be able to take off with as little as 300Hp form the engine because of its large rotors. Thank you Zeljko Fabijanic for the wheel. _____________________________________________ Don't forget to hit the like button if you decide to download.
