Abstract
A toy airplane which is to be constructed of two pairs of overlapping wings which are to flap relative to each other. Each pair of wings is to move in synchronism with respect to the fuselage. The flapping motion of each wing is driven by a crank arm which is attached to a drive shaft. The different crank arms are located in planes which are displaced ninety degrees from each other so as to smooth out the operating torques. There may be employed a single operating drive shaft or there may be employed dual drive shafts which rotate in opposite directions. The airplane includes a tail section which is adjustably mounted upon a fuselage.
