THE WING ALONG THE FUSELAGEA distinctive feature of this model of rocket plane is turning the wing. It is set along the fuselage, which eliminates any possibility of the appearance of the spiral during takeoff.

THE DESIGN OF THE MODEL. Rail-the fuselage is made from pine slats of variable section, which by gluing to form a T-shaped rigid structure. This helps eliminate the deflection of the fuselage when the wing is in the takeoff position, with some tension.
The stabilizer and fin are made of balsa glued to the fuselage nitrocream. Container for engine — paper, its cone — foam.
Wing balsa plate, of elliptical shape in plan, profile, coated with nitrocellulose lacquer, then cut. The two halves are interconnected by an elastic plate (aluminum 0.3 mm), in which a hole is drilled for the axis.
1 — stud-lock (OVS Ø 1 mm), 2 — stop (celluloid), 3 — washer (brass 0,3), 4 — spring (OVS Ø 0.5 mm), 5 — hole for the locking mechanism 6, the axis of rotation of the wing (brass Ø 2 mm), 7 — plate (aluminum 0.3 mm), 8 — emphasis (celluloid 2 mm), 9 — pin fastening elastic return 10 — the elastic return 11 — washer (plate 0.3 mm), 12 — wing, 13 — support plate (plywood 1.5 mm), 14 — fuselage 15 — fairing (plastic).

Down below, in the joint, glued a strip of silk. The wing pivots on the axis of the top is pressed by a spring, and the bottom rests on the base plate, bent at an angle of 10° and the angle creates a V-wing. When the wing for take-off is placed along the fuselage, the left side of the console, it comes in a cutout of the keel, and the right emphasis of celluloid, which is a continuation of the border of the pylon.
Return gum seeks to deploy the wing in a clockwise direction. But it holds the locking pin passing through the wall of the container rack and the fuselage and the hole in the wing. Once there shoot the exhaust of the engine, the locking mechanism releases the wing, and it returns to the planning. To the wing stand in a certain place, to the bottom surface it is bonded, the emphasis of celluloid.
The entire model is covered with three layers of nitrocellulose lacquer and a layer of caponata. All up weight is 40 kg.
