MODEL AIRCRAFT FOR BEGINNERS

Presented control line model airplane is easy to manufacture and has good features that allow easily recommend it not only for training but also competitive performances for beginners.

Description of  model airplane
The fuselage of the aircraft model.

 Your sketch full size drawing, prepare all the details of fuselage (materials are in the pictures). Each board docked plywood 1,5 mm (front) and balsa of the same thickness (back). To increase the area of ​​the adhesive joint ends grind workpieces at 45 °. Gluing lead on a flat surface with thick cyanoacrylate glue. After drying boards combine to fit together.
The assembly begins with mounting internal set on the left side. Since the aft fuselage narrowed in thickness during the assembly under this part to put a wedge support rails. Engine support  is glued with epoxy resin, other details - superglue. After finishing installation of internal set, stick starboard thick superglue (glue medium thickness would prevent anything to correct in the case of bias). Keel cut out of light balsa thickness of 5 mm. When finished profiling, it is glued to the fuselage with epoxy. Ready  fuselage and one coat of nitro lacquer varnish (diluted nitro AGO or "Skin"). After drying, the tail (balsa) part of fiberglass paste over 0.03 mm in two-component parquet lacquer, followed by grinding the surface.
Cord wing aircraft model made of balsa and collected mainly on superglue. Rib batch process method of metal patterns. Spouts ribs that keep lodgement chassis  plywood 1 mm, and the central rib reinforced fiberglass 0.03 mm. Facilitate internal ending. Then it is glued thin springs to print drafts. In the outer ending fixed ballast 25-30 g Shelves spar - from dense balsa (about 0.2 g/cm3).
Details of the junction in the center of the wing on an elongated "whisker" epoxy. Reinforce the joints with plywood plates 3 mm thick, which also serve to set the axis of rocking. Front and back edges of the dense cut balsa. Lodgement mount chassis (rack lime) complement vertical arrangement of elements of plywood 10 mm, the slot which will include the end of the Z-shaped wire rack. This jack is reinforced with metal tube 4x0, 5 mm. Gathering frame on-site axis and rocking it with connecting cable and pull the flaps.
The next stage - the alignment rib ends with a long bar with the skin. This work requires special attention - tails ribs have shelves, and so on the trailing edge spar is shoulder height profile (1.5 mm thickness for forehead). The sheet is then cut out of light balsa wood and fitted to the frame. When pasting forehead veneer fixed pins and rubber rings. Finished with a forehead, sheathe and the central part of the wing. Finally profiled front and rear edges. The entire frame is covered from the inside to protect from moisture layer of liquid nitro lacquer. Ready wing flaps and adhesive qualities film type.
Plumage cord model airplane. For the stabilizer and elevator use average (0.1 g/cm3), 8 mm thick balsa. Details profiled according to the drawing, triangles glued solid wood under the ends of the U-shaped bracket and tight film Mono-Cote (you can use a cheaper type of film Solar-Film).
Chassis cord model airplane. Rack bent steel wire SZ mm. Lightweight wheels on one side fixed soldered plate, and on the other hand - the original removable sleeve. The tail is made of a wire rack R2 mm. It is glued to the fuselage portion flattened and make her cuts.
Cord-rotor aircraft model. For the experiment, except the engine OS MAX .40-LA, a model was established and Super Tigre G-34. It turned out that in this class of models, low-speed and high-torque "Japanese" is superior to the temperamental "Italian." Carb OS MAX .40-LA replaced homemade conventional type. On models use a fuel tank made of plastic bottle volume 130-150 ml, and fitted with the tracking system.
Even with the fuel supply pressure are picked up from the muffler, fill and drain tube must be made through the right side of the model. Then after take-off fuel is discharged into the muffler. If you have problems with the settings of the engine between the tank and the fuselage is useful to lay foam rubber thickness of about 5 mm - then the vibration will not cause foaming of the fuel in the tank. By the way - due to gasket thickness can adjust the lateral displacement tank.
Cord assembly aircraft model is an epoxy resin with constant control the relative position of the main units. Temporarily install the rudder and flaps, check the ease of control and regulate the deviation control surfaces  then hinges glued in place. The fuselage is painted with synthetic enamel, resistant to methanol. Fragments-branded paint finishes for the films and film. For flights to the OS MAX .40-LA are good homemade propellers 260x120 mm.
