Yes. It would be called a helicopter. Full sized ones can have fuel engines, which can carry more energy per weight and can go further. On the other hand, they are heavier and not as durable because of that weight. They cannot change directions like this mid flight.
- yread 13y agoThis one has a gasoline engine
- hengheng 13y agoIt's battery powered, see the battery around 4:25
- aaren 13y agoCan you explain why? Is it to do with the bulk properties of the materials not varying with scale? Or scaling with some power of length < 3? If you tried to spec a full sized helicopter engine to make speed changes like those in the video would it tear itself apart?
- barrkel 13y agoYes. Mass increases with the cube of scale, while structural material cross-section area increases only with the square of scale. So insects can have miniscule legs, while elephants have tree trunks, proportionally.
- mturmon 13y agoRight, sometimes called "square-cube law" (http://en.wikipedia.org/wiki/Square-cube_law http://en.wikipedia.org/wiki/Square-cube_law). Worth knowing about so you can explain to yourself the differences noted above.
- jamesaguilar 13y agoThink about it. Ants can carry six times their weight, while larger creatures could never accomplish that. I don't know the physics behind it, but it's not hard to see that small things can have greater strength per mass than large things.
