Justwantahover: Have you considered a practical pedal plane? That would be fun. Better than a chopper (even if the chopper does work). Cos the chopper won't go as far or stay up for as long. And everybody wants a pedal plane.
Tim Lewis: +Justwantahover pedal planes have been more successful and they are more efficient. There has even been one that made it across the channel called the Gossamer Albatross. I bet the rider was huffing and puffing, working his butt off for a couple of hours trying to keep himself from crashing in the sea! I could just imagine - aah! Calf cramp! splash... Now I'm screwed!
CNL _: +Tim Lewis wow, i didn't know that was possible, i'll even look it up. it's certainly because fixed wing aircraft require quite a lot less energy to produce the same lift, if they are designed for it.
