Drive over land then take to the air!
The Best of Both Worlds
You've no doubt seen those fantastic mini radio-controlled helicopters that can take off from the palm of your hand and fly 50 feet in the air? They're typically £30-40 and despite their appearance they can only fly up and down, not right and left. You've also surely seen the endless array of radio controlled cars that proliferate shopping malls at Christmas? Now imagine someone clever, like say the Science Museum, decided to make a Helicopter that could actually turn right and left mid flight and could drive along the ground like an RC car... Welcome the rather cheesy but very aptly named (and precision engineered) Heli-Car.
