    摘要： The present invention relates to a stick fuselage of a model aircraft that also combines an aircraft nose and a main wing brace. The stick fuselage adopts a transverse H-beam as a main body. Two sides of the main body have continuously annular bodies as reinforcement structures. The aircraft nose is connected to a head of the stick fuselage, and has a concave spherical surface and a spherical convex to form a spherical pairing. The middle of the stick fuselage has a fuselage sleeve. Two ends of the fuselage sleeve are connected to a hollow ring respectively to form the main wing brace. The main wing brace uses a hollow double ring as a basic configuration for division assembly and accumulation assembly so as to make a monoplane, a biplane and a triplane.

    摘要： A propeller driven toy comprising a hollow cylindrical elongated fuselage having radially spaced fins mounted thereon, a front propeller rotatably mounted on the forward end of the fuselage and having a circular hub provided with inwardly facing recessed notches along its periphery, four radially spaced blades and a drive shaft extending inwardly through the center of the hub; a rear propeller substantially identical to the front propeller rotatably mounted on the rear end of the fuselage in axial opposition and counter-rotating to the front propeller; a rubber band interconnecting the drive shafts and their respective hubs; a locking mechanism housed internally of the fuselage comprising a wheel rotatably mounted on a horizontal shaft, a lever having its inner end rotatably received on the wheel shaft and interposed between the sides of the wheel and having its outer end free to project outwardly from fuselage, a pair of elongated lock rods in offset axial alignment with the fuselage having their inner ends mounted on the wheel and their outer ends adapted to engage the recessed notches; a spring slidably received on one of the lock rods and adapted to compress when the rods are extended into the notches thus inhibiting the rotation of the propellers; and a catch employed to hold the lever in a position perpendicular position to the fuselage; and wherein turning of the lever from its perpendicular position rotates the wheel to retract the rods out of the notches, thus releasing the propellers.

    摘要： A rubber band powered model airplane is provided having an elongated body made substantially entirely of a lightweight expanded, cellular plastic. A passageway extends completely through the elongated body to accommodate a rubber band motor. In one form, the passageway is lined with a thin walled, non cellular tube of substantially greater rigidity than the material comprising the body. The tube serves to both longitudinally reinforce the body, and retain the nose and tail fittings for the propellor and rubber band motor.
