The training model “air combat”. The emergence in recent years of specialized model stores are relatively inexpensive and fairly powerful electric motors allow to transfer a number of classes of models to electric drive. The result was the appearance of the model aircraft new fans that previously stopped the need to get model engines internal combustion with all its attendant problems — their high cost, short lifespan, low reliability, problems with the acquisition of fuel components, the complexities of starting, running and operating.

Engine MD-5 Kometa is produced in large series for many years and is established on the models of different types. To simplify manufacturing and reduce the cost of manufacturing allows derogation from increased individual adjustment of the prototype. This leads to the fact that the production engines develop power below possibilities inherent in their design. Only individual samples with the perfect mix of details showing good results.
Sometimes the competition for RC model, not obeying commands, is out of sight. Flies knows where the result of months of labor and expensive equipment. A simple automatic device developed gorsyut Alma-ATA will provide a forced fit of the model. It will stop the engine after some time after the failure of the receiver.
Imagine a vast red-hot desert with shifting dunes. In such Sands are buried and tracked ATVs. But… like tumbling over the sand dunes, we were quickly approaching a strange device. The prototype of this rapid Rover for Sands created in a laboratory experimental simulation and design Cute the Siberian branch of the USSR Academy of Sciences. The guys gave him a playful name “Changeling”.
The model is made of balsa medium density (150 mg/cm3) and covered with microfilm. The fuselage and tail boom round (tubular) cross-section of plates with a thickness of 0.5 mm. Braces — thread No. 80.
Brutal cold, snow storms and drifts, sometimes for many weeks terminated the transport connection between towns in the far North. Even a helicopter in this weather is not up in the air. And if the sick man and need urgent help how to overcome snow desert?
This model is designed for pupils of 4-5 classes involved in a circle of the second year. At the regional competitions 1974 Sergei Lebedev, speaking with a model with the same contours and dimensions, took first place.
Not everyone can use the balsa when building models. Not everywhere is the enamel and long-fibre paper, stitched. That’s why modelers are constantly looking for new more affordable alternatives. We offer rezinomotornaya model of foam by weight, durability and flight characteristics are not inferior designs made of balsa, and in some ways even surpasses them. Some days it can make any novice an aeromodeller.
For making models are used, the stems of cereals: oats, rye, barley, Timothy and reeds.
This model was designed by students of Victor Pisarev, Alexei Knizhnikov and Nikita Novikov. They built it in the ship laboratory of the Moscow city Palace of pioneers. High speed of -10 m/s, stability on the course and high bench evaluation allowed the boys to take first place in the class of civil courts and become the champion of Moscow among younger students. The model was shown at the international exhibitions of technical creativity of schoolchildren in the United States and Canada. Given its description.
