    Abstract: A flight control apparatus (10, 210, 310 or 410) for use in a model airplane (50, 250, 350 or 450) is described. The apparatus includes a weight (20, 220, 320 or 420) and a resilient band (24, 224, 324 or 424). In the first three embodiments, the weight is mounted in a housing (12, 212 or 312) with the resilient band connected between the weight and the housing. In the fourth embodiment, the weight is mounted on the fuselage (452) of the airplane. The airplane is launched using a standard slingshot-like launching device (56). The resilient member (56A) is mounted around the extension (22, 222 or 422) of the weight in the first, second and fourth embodiments. In the third embodiment, the resilient member is mounted around a hook (354) on the head (350A) of the airplane. To launch, the user (100) holds the tail (60) of the airplane and pulls forward on the post (56B) of the launching device which pulls the weight of the apparatus to the forward most position.
