actually keep is stall
As you know, in normal flight, the rudder causes the plane to pivot laterally on it's axis. Unless the effect is counteracted by the ailerons, at the same time the plane tends to roll. Right rudder left roll and vice versa. This is because the rudder sticks up above the fore and aft axis of the plane. At stall speeds, the roll affect is still present, but the affect on the wings is greater, because of the difference in the relative airspeed of each wing. Providing the plane is flying straight and level, at the instant of stall both wings are level. At that point, if say the left wing starts to drop, right rudder moves the tailplane to the left, thus increasing the airspeed over the left wing, which can cancel the stall on that wing. At the same time the right wing is travelling even slower, so unless you use just the right amount of rudder, the plane can easily spin to the right if that wing is allowed to drop too far. The idea is to balance the plane with the rudder, so both wings remain level, until flying speed is regained.
Yup. The principle is the same as for a powered plane, but I imagine the yaw affect of the rudder on the wings is more severe because of the greater wingspan of a glider. I'm no expert on flight aerodynamics, so if my explanation is not as clear as it might be, that's my excuse. :-) Mike.
