It's a remote controlled air plane that uses a different motor. LOL we did something like that in science last year and it was pretty cool once, then it got boring.
Meh, I fly 500-1000 dollar RC airplane models as my hobby second to roller coasters. They are pretty cool, the boat is propeller powered and just has some aelerons on the fins.
Looks really cool though, as it can go on water and grass, and then fly too. But i bet its pretty hard to control and i would end up making it do an Oblivion impression and then accidentally letting it smash face first into the ground.
