    I would guess that aerodynamics is like SLIGHTLY more complicated than Newtonian mechanics, however try this: www.google.com

    Helicopters hover. OK.

    They gain lift on exactly the same principles as an airplane. One should consider each rotor of the chopper to be its equivalent of a wing of an airplane. Difference between the two? The airplane requires horizontal velocity for air to pass over the airfoil where as the helicoptor does the same via the rotation of it's rotors (wings). Therefore it is able to hover. Amirite?

    sort of

    a helicopter hovers because the rotor spins at a pre-determined speed great enough to pull the helicopter off the ground. the helicopter then needs a counter rotating device to stop it spinning around in circles (ie, a tail rotor). the helicopter moves in different directions by changing the angle of the rotors accordingly

    lift> gravity = up. lift<gravity = down. lift=gravity = hover. physics at its very simplest.
