At competitions in ship modeling sport of most interest among audience and many athletes call the competition of high-speed radio-controlled models figure chart. The most popular of them can be considered a model of the class F3V — free design. Their creators usually distinguished by deep knowledge of the operation of radio equipment, motors of internal combustion, the skill of “navigation” and of course specific practical skills.
Every year, more reservoirs becomes “closed” for motor boats. What in this case do Amateurs vodnomotornyy tourism? To put their vessels on the joke? In any case! It’s time to recall the sail. Sailing rig can be a real alternative to a rattling, smoky, polluting water bodies with suspended motor.
Category high-rise models (S1) is one of the oldest in the rocket modeling. Since 1985, the sixth world championship, it is firmly “registered” in all world and European Championships. It should be noted that our sportsmen became the leaders in it, and of the eleven world Championships last twenty years became seven-time Champions.
Constructed this model of the Bulgarian athlete G. Lalev — European champion in class S-3-A 1979.

They travel hundreds and thousands of miles of impassable tundra, cross bogs and swamps not freezing in the harsh winters of the river, deep snow.
Parameters and characteristics of the model correspond to the categories Ѕ8А and Ѕ8В. The diameter of the container under the engine selected in accordance with a cross-section of the sleeve (MRD-2,5-3-3 or MRD-5-3-3). We present several design and technological recommendations for the production model.
A failure to “stand” due to poor paint quality model. A crucial role when applying color coating plays spray. I tried them for twenty years are many, but none fully satisfy me. That’s why in the end had to undertake the designing yourself. Took a commercially available spray “Shine”, refined some details and making some new ones. But in principle the device fully to make yourself; all of its elements are quite simple.
