Phun Helicopter - rotor slow motion

Detail of rotors used in this phun helicopter.

When an engine make a blade spin, the air friction produces up and down forces of same strength, because the same amount of blade's area is pushing air downward and upwards on each spin. The idea here is to reduce the blade's horizontal area when it is moving upward, to unbalance forces and make the entire structure lift. The other side of rotor must have the same structure turning reversed to compensate, otherwise the entire velhiche would sping uncontrolled on sky (here is the same objective behind the tail rotor on real helicopters).

[AVerbene]

set the colision to nothing

like really flies, or really moves

i dont understand, when rotor starts turning, the centrifugal force brake it and doesnt works right....can i download your rotor on phunbox?

Oh, that kind of slow motion. ;)

[wduty]

No, its choppy because was my lovely old Pentium 3 1GHZ =)

It's choppy because it's in slow motion...

poor pc, but cool chopper ;)

Wow phuntastic! Like a bird, like a pigeon took off the ground!
