FOR HIGH-SPEED RADIO CONTROLLED MODEL WITH INTERNAL COMBUSTION ENGINES. Model of class “Grand Prix”, which the figure shows a contour is given in scale of 1 :8. Engine — the meteor-MD-5, but it may fit “MK-12V” and “Rhythm”. With the last model’s speed will be somewhat less.
MODEL YACHTS “10” is very popular with modelers-boaters. It is easy, manageable and fast. The casing can be made of plastic or stacked with a shell of mm plywood.
Clash of pigeons with a pigeon taking off at the Paris airport of Orly liner “the Boeing-747” has led to the stop of one engine and an emergency landing before the plane continued an hour circling over the landing strip and leaked 40 tons of kerosene. The total loss of engine repair, fuel theft, downtime of the liner within ten days amounted to about $ 1 million.
This is one of the most heavy and high-speed models. It belongs to the class “A-3” according to the Rules NAVIGA. The model consists of the following main components: hull, floats, motor (10 cm3! with shaft, propeller and fuel tank. Hull and floats are made from a light and soft wood, preferably balsa.
The proposed model has a classic pattern glider A-2 “Hawk” in a reduced form. The main material for its construction – balsa. I must admit that over the last three or four years, such constructions appear frequently in competitions of any scale (though the schoolchildren they are made of more affordable material – to-ceiling foam). A return to this scheme due to the stability of the flight of such a rocket plane. Except only on the runway (starting) station.
The competition rules for models raketoplana prohibit use for take-off surface, creating aerodynamic lift. Flight model can be scored if, at the time the hoist is used only reactive SIPA engine.
Offer paired schematic model made in model aircraft laboratories of the station of young technicians in the city of Nikopol. Structurally, it is a “aviamarch”, consisting of carrier-glider attached to the carrier special locks rezinomotornaya model airplane.
In the early 70-ies before the Soviet athletes-automodellista was a challenge: dvuhsotmetrovy to exceed the threshold speed in the class of models 2.5 cm3. These days, the speed has mastered many of the leading athletes. A sharp jump occurred in 1973, when during the season a few models exceeded the speed of 220 km/h.
The triumph of the Soviet athlete V. Extencive in the class of models of gliders ended the world championship in 1973. Short nose and a relatively small shoulder are the main design features of the model of a champion. The layout is very different from the standard, which is used by most of our leading modelers.
How to ensure reliable and trouble-free fit of a model rocket? The solution to this technical problems struggling for many modelers. According to statistics, more than half of the models after the descent have breakage. But time goes on, experience is gained, more diverse ways of salvation models.
