Serious modeling starts with a small design. Noteworthy experience in the construction of the simplest models of gliders have gained members in the House of pioneers and school students of the Frunze district of Leningrad. In the first stage they do developed in the circle training model, then the glider “Junior” class A-1 and only then start making the model A-2, which ends the program of training of young modelers-athlete. Today the leader of the group V. Bashtannik acquaints readers with the first two gliders of Leningrad.
TRAINING GLIDER MODEL
He is still a pilot. Because I do not imagine myself without the sky. However, today the pilot He doesn’t goes up to the sky at the controls of an aircraft in the air it shoots miniature rockets, to which Vladimir Menshikov put your love to the sky, the pursuit of excellence. It was here that he realizes what gave him the aircraft.
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 480×800
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°).
