ABSTRACT:
A control member is rotatably mounted on the fuselage or on the wing of a model aircraft in spaced relation with a supporting surface of the fuselage. A gear leg is supported at one end by the control member and supports a landing wheel at its spaced opposite end. The gear leg extends radially of the control member. A torsion spring is coaxially mounted with the control member for storing energy when the control member is in a position whereby the gear leg is fully extended for ground operations and for releasing stored energy to rotate the control member in a manner whereby the gear leg is retracted for flying operations. A gear retracting initiator coupled to the torsion spring initiates gear retraction. An extend lock locks the gear leg in its fully extended position. A retract lock locks the gear leg in its retracted position. An actuator in operative proximity with the extend lock and the retract lock assists in locking the gear leg in its fully extended position and assists in locking the gear leg in its retracted position.
