Controlling the Direction
The tail of the airplane has two small wings, called the horizontal and vertical stabilizers, that the pilot uses to control the direction of the plane. Both are symmetrical airfoils, and both have large flaps on them that the pilot controls with the control stick to change their lift characteristics.

Vertical tail wing

With the horizontal tail wing, the pilot can change the plane's angle of attack, and therefore control whether the plane goes up or down. With the vertical tail wing, the pilot can turn the plane left or right.

The plane's main wing is 40 feet long from end to end, and about 4 feet wide. On the inner portion of the wing, there are flaps used during takeoff, landing and other low-speed situations. On the outer ends, there are ailerons used to turn the plane and keep it level.

Flaps

The flaps are actuated by electric motors in the wing. Also enclosed in the wings are two fuel tanks, each of which holds about 20 gallons of gas.
