Aircraft model Yak-3 Homemade radio-controlled model aircraft Yak-3.

On the Internet all the time it is said about the poor manageability of models of copies. Here we are at the same time and we will check all these statements.

Drawings of the aircraft model Yak-3 First of all we download the drawings of the aircraft model , we scale it to the size of your future model and print it whole (you can print the individual elements).

Now about the materials that have been applied. To build this model did not apply balsa. Power elements were cut from 2mm plywood (from boxes from under the fruit). Reiki sawed out of pine. Motorama from aspen bars. The wing is made of a ceiling (ceiling tiles) and covered with ordinary film.

First of all, it is necessary to determine the size of the future model. Our choice was limited to the engine we had at the time, namely the 2.5 m3 caliber engine. Therefore, the model was obtained with a wing span of 1150 mm and a length of 950 mm. According to the drawing, they made racks and cut out ribs from the ceiling tile. Cutting the grooves for the ribs-spars in the ribs, we glued them with joinery glue (you can apply and glue for the ceiling "Titan", "Dragon", etc.).

The engine is 2.5 cu. Non-rubbers

Then, from the sheets 500x500 mm, the lower halves of the wing hood were cut out, the limes or aspen bars cut out the amplifiers for fixing the chassis racks and the rib amplifiers in the fixation points of the racks.

Making wings Wing Closure

After that, cut out the upper halves and wrapped the upper surfaces of the wings.
To fix the skin to the point of drying, we used an adhesive tape, taking the upper and lower parts of the skin between each other.

Covering of wings Wing model

After the drying of the cover, we begin to make the leading edges of the wings. To do this, to the front part of the wings we glue several strips of the ceiling, which after drying are rounded with sandpaper glued on the bar.

Now they joined both halves, while strengthening the place of gluing together with plywood inserts. The wing is easily removable and fixed to the fuselage with a wooden spike and two screws with wide hats.

Homemade model aircraft Airplane manufacturing

It's time to deal with the engine compartment ie. With the nose of the aircraft. I had to make it twice - the first time exactly according to the drawing - how it was possible to make the front part, without wiping the blanks to the holes it was not clear. The second attempt was more successful - I had to extend the nose by 5 mm and pre-glued thicker lateral brusochki.

From the picture you will understand how it was possible to solve this problem. In addition, I wanted as much as possible to hide the motor for a strong nose.

Manufacture of engine compartment Engine mount

To make the compartment we used aspen brusochki and 2mm plywood. From the brusochki sawed out the details and after gluing it was processed using an emery wheel and manually grinding skins.

After pre-treatment of the bow, glued to her cheeks of 2 mm plywood and the second frame. The result is approximately the following:

Fabrication of the nose part of the aircraft model Engine mount

Now we cover the inside of the engine compartment with several layers of nitro-lacquer to protect the wood from fuel and oil, as well drilled a drainage hole in the lower part. Once again we checked how the motor "sits" and made a fine finish with fine-grained sandpaper. The finished bow was like this:
