For the manufacture of tracks required plywood thickness of 10 mm, and it is important that it was dry, smooth, uniform thickness and without lagging layers. Each sheet should have the dimensions 1500×1500 mm. If this condition is not met, installation of the alignment and connection of individual components is greatly difficult. Straight sections are cut on a “circular saw” along the cross-section of the fiber, and then butt and trimmed. The finished strip should be sized 1500×480 mm. For Assembly of straight sections of the route will require 27 partitions of size 480×1500 mm and 4 mm. in size 480×800SPEEDWAY IN THE GYM

Start with a careful study of the drawing and then get to work. As the present motor vessel, the vessel is stacked On a smooth plywood, 3 mm thick, transfer the exact dimensions of the deck and frames using carbon paper or tracing paper. Remember that on the deck of the elephant of plywood will be parallel to the axis, and the ribs vertically.
The model of modern missile boats (Fig. 1), developed by the Central marine club DOSAAF intended for competitions.
“…The barge is loaded mast and folded sail, half pushed into the sea, floated on a light wave…
At the world Cup 1978, held in the city of Yambol (Bulgaria) in the class RC raketoplana S-4-D (the maximum mass of 240 g, the total impulse of the propulsion system 10-40 n*s) a convincing victory was won by the American athlete Harold Anglin. In three rounds, his model flew for 5 min in the fourth, additional, 3 min 23 s.
Czechoslovak athlete A. Turnips became the winner of the world championship held in 1978 in Bulgaria. He performed with the model missiles S-6-A. the Distinctive feature of his model — longitudinal connector housings. The model of this design was the only one in competition for the duration of the flight tape.
Flying model aircraft with electric motor is silent and doesn’t poison the atmosphere with exhaust gases. Model spared from the shaking characteristic of internal combustion engines, and, consequently, radio equipment, installed on the models with a motor, works more reliably (especially servos). That’s why recent sales microelectronical new grades immediately attracted the attention of modelers. However, the first samples have revealed some of their weaknesses: the unreliability of the brush mechanism and bearings, lack of ventilation of the armature and ferrite-barievykh magnets. Used for the manufacture of parts of the armature and commutator polystyrene cannot withstand high temperatures (150-170°).
These beautiful and flying planes is very simple. They can do and the guys who have not yet engaged in aircraft modeling. To work they need a dense drawing paper (drawing paper), a few dry and straight straws Ø 2-2,5 mm (grasses, bluegrass, wild oat), silicate office glue. Also needed is a blade for a safety razor, jig saw, ruler and pencil.
Room model pricelet really similar to a Hummingbird. This inhabitant of South America — the smallest of the birds — have much to learn. It can still hang in the air and even fly backwards. Our model is no less maneuverable. The design consists of two polycrylic hinged to each other stabilizer, as well as double-girder fuselage, which is attached to the rod with the rubber motor. He drives the crank mechanism polycrylic. Weave wings and stabilizer — capacitor or a tissue paper.
As the history of aviation, the aircraft can be done from almost any material of the First airplanes he built from bamboo and percale, later, aircraft materials steel Yes spruce pine, them was soon replaced by aluminum and magnesium alloys, but today the high speeds require the use of titanium and high strength steels.
