SCHEMATIC MODEL OF THE AIRFRAME

Before starting work, carefully examine the drawing and description. Then prepare the tools: small plane, a sharpened knife, pliers or pliers and a jig saw with saws. Materials you will need: a pine rail, a small sheet of tinplate, paper, spool of white thread No. 10, plywood thickness of 1 mm and 3 mm, or micuenta tissue paper or polyester and nitrogly (it may be enamel, “AGO”, supercement, etc.).

 

For the leading edge of the wing, take pine slats 4X4 mm for the rear 2,5X7 mm and the ribs 2,5X3 mm.

 

Warming over the flame, give the ribs the shape of the profile. To get the angle of the V, glue, and then tape the thread two strips of sheet metal with a width of 7 mm and 4 mm to the ends of abutting edges, as shown in the figure. In places of gluing the ribs to the edges with a knife cut the grooves. To rib better behaved during gluing, they should be pressed to the edges believeme clothespins.

 

To prepare the stabilizer Reiki 3×2 mm.; Its design is clear from the figure.

The keel shape of a rectangular trapezoid with bases of 70 mm and 50 mm and a height of 70 mm fabricated from strips of the same cross section as the stabilizer. For the rigidity of glue reinforcing rail.

 

The toe of the fuselage made of plywood 3 mm thick with a cutout for the ballast. To wear saw out a few notches for handrail and drill a hole Ø 3 mm for pine pin. It is needed in order to attach the wing to the fuselage. Camera for ballast on the sides cover plywood with a thickness of 1 mm, and the top drill a hole Ø 3 mm. At a distance of 80 mm from the toe of the fuselage glue a small platform for the wing made of plywood with thickness of 1 mm.

 

The tail boom is in the form of strips 3X9 mm thick, to which is attached the nose part. On the same rack installed on top of glue the stabilizer and fin.

 

 

 

To fit the model or mcalenney tissue paper or Mylar. Apply glue to the edges and ribs, put on top of the paper and press it with your fingers. Then glue the middle strip of paper. The polyester cording on the glue BF-2. On the finished joints spend hot, but not hot iron.

 

Adjusting the model is necessary in calm, windless weather. In the 3 mm Ø hole in the toe of the fuselage pour a shot or small pieces of lead to the center of gravity moved under the wing. Try to let the glider with it. If he quickly landed (dived), it is necessary to extract some of the goods, if, on the other hand, soared (skopiroval), and then cool down, lead must be added. A well-adjusted model should fly when running with the hands of 17-20 m.

 

Now try to start up a glider with a Leer. They may be of strong string or fishing line length up to 30 m with steel ring and box at the same end. A ring to hook it on the groove at the toe of the fuselage. The one who draws the rail, should run against the wind, looking glider. Another with the model in hand, runs a few meters, ensuring that the guard rails were stretched, and releases it. Model smoothly gets up high. As soon as the glider “climb” to the upper point, to weaken the guard rails, ring POPs out of groove (this can be found in the check box), and the model will start free plan.
