Depending on design, airfoils used in general aviation, stall at angles of attack between 16 to 18 degrees. When the airplane is stabilized in the approach attitude and speed, begin to smoothly and slowly bring the nose up to an attitude which will cause a stall. As the airspeed slows into the white arc, extend the wing flaps.

The wings are designed with an airfoil shape, curved on the top and flatter on the bottom, creating a pressure difference when air flows over them. Each rotor blade acts as an airfoil, and as it rotates, it moves air over its surface, generating lift. This pressure difference produces lift, allowing the aircraft to ascend.

They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. This is why the typical airfoil shape has a curved top and a flat bottom, especially in slower-speed general aviation aircraft. Newtons Third Law tells us that we need to push air downward to produce an upward force.

In order to minimize the effects of torque on the aircraft, the Shiun was equipped with the MK4D variant of the Kasei engine, which was modified to accept contra-rotating two-bladed propellers. Additionally, the Shiun incorporated a laminar flow airfoil to reduce drag.

Another advantage of the counter-rotating props is the elimination of torque roll. This is the tendency to dig in the left tip float during takeoff while countering engine torque. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.
