Aerodynamics at it's best.

Just Tryin' to Get Off the Ground
It is essentially just knife-edge flight. The fuse is providing the lift and the rudder becomes the elevator. Missing a wing actually helps by reducing the rudder pressure needed to hold knife-edge. The wing that is still attached tends to point upwards because it still produces lift; however, it also still creates drag. This drag causes the plane to yaw toward that wing. Or were you talking about R/C and the whole flying without leaving the ground thing?
