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.

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”.
Copenhagen, 1934. International aviation exhibition. Among the machines for the development of the North paid particular attention to the snowmobiles of OSG-6. Comfortable and shared, they differed from the other designs of technology, a good layout. Powerful aircraft engine M-11 allowed them to reach the speed of 80 km/h.
The speed of fast motor vessels — boats, scooters and even simple boats — are growing. This is logical not only in sports but also in everyday operation of such ships, because the increased speed of some vehicles inevitably make others, at this stage, lagging, or catch up, or to go from the arena, replaced by a more reliable, fast and economical. But the growth speed on the water is not as painless a process as it might seem at first glance.
“Suli’s not pie in the sky, give it to the bird in hand…” So says an old Russian proverb. Don’t know whether it was guided by the famous Lithuanian designer Bronis Oszkinis, creating your initial glider training, to which he gave the name (in Lithuanian “ZIL”). At the all-Union meeting of workers and youth gliding schools and the design of the asset held by the magazine “modelist-Konstruktor”, “Tit” was unanimously recognized as the best ka date training glider. This car can now be seen on many club airfields in our country. Very simple in design and reliable in operation, it has won wide sympathy not only of the younger generation of glider pilots making their first steps in the sky, and veterans of aviation sports.
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.
What could be easier and more efficient wheel? This question asked a students of MVTU named after N. E. Bauman, and replies to it may serve as the exhibition NTTM-76, which aroused universal interest of visitors. This interest is not accidental: the mechanisms were distinguished by the uniqueness, originality, novelty.
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.
