The release of carbon dioxide industry miniature engines has caused many young technicians ‘ interest in the models in which you can use this reliable, silent, environmentally friendly motor. In the “M-K” have already talked about a few simple ship models with such engines. Today we offer you to make simple model airplane motor CO2. By construction, this classic high set scheme, made without the use of scarce balsa wood — mostly pine and light lime. The fuselage of the model are collected from pine spars a cross section of 2X2 mm and cross-beams of the same section. The Assembly is the simplest slipway, made of two sheets of plywood, covered with plastic wrap — so that the workpiece is not glued to the slipway. Build order is as follows: the rack-bars fixed with pins, then cut between the frame crossmember and finally the joints fill with epoxy glue so that between the blanks formed a fillet — a fillet transition. Billet spars are pre-bent over a candle flame. First, it makes sense to applied to the wall side of the fuselage, and then collect from half of spatial farm. Please note that the front spars of the fuselage together reinforced frame — lime plate thickness of 3 mm, it also serves as the basis for the engine mounts. The front part of the fuselage top and bottom (bottom to the rear edge of the wing and top to the front) paste over fake veneer thickness of 1 mm.
We are all accustomed to the fact that it is a machine fit only to acquire initial skills of piloting. In most cases, training is built almost without any requirements for in-flight properties. The main thing — to provide the maximum ease of manufacture. Eventually, when the athlete will be accepted for the design of the following models with which it will compete, will be subject to calculations and aerodynamics, and strength of materials, and materials science. But at first — what to suffer, whether… And see the light polulotosa “snags”.
The proposed model is performed according to the scheme “duck”. The stabilizer is located in front of the wing, contributes to the sustainability planning mode. A deviation to vertical position after deployment, a simple “timer” (wick device ignites the expelling charge motor) ensures a safe landing apparatus.
We can safely say: engine MK-17 “Junior” is familiar to all modelers. One of the most popular among beginners and are produced in large series, it encourages the modeling of thousands of boys. Under the motor created a lot of industrial kits, semi-finished products. With models equipped with “Juniors” are the first sports categories air-, ship-, avtomodelisty-students and young builders of the different copies.
Continuously growing speed racing car, top athletes, designers are finding new technical solutions that increase the speed of avtopoligon, new methods of forcing-engines, better ways of suspension. And as a natural result — new records. So, last year, the master of sports of the USSR, Leningrad A. Medvedev at the all-Union competition “Match the fittest” broke the record of the Soviet Union — his polutorametrovy was racing the distance at a speed of 223,880 km/h!
Only four minutes, the athletes rakatomalala to prepare for the start. How much do you need to keep up with the time flying at the competition as if one moment: to install the model on the guide pin. To connect Elektrostal, to determine the atmospheric conditions at this point and calculate the direction of flight, accurately to execute the command “start!”.
Today, we first introduce you to the most massive representatives of the ship-class F1-V. This high-speed RC ships with engines working volume of 10 to 15 cm3. One of the most successful developments in this subclass is the model A. Baidebekova.
The design sports a model rocket with a streamer class Б6А traditional. Athletes rocketmodeler repeatedly noted that models in this class closer to a kind of optimum. Now much depends on the quality of manufacture and Assembly of their components. The proposed model is performed based on these requirements, can show good results in competitions.
What a pleasure to start the thread right under the clouds even a simple crossing of two strips, covered with tissue paper! But in our time it is available only to inhabitants of rural areas… Try to catch a good steady wind at the site, surrounded on all four sides by a fence of high-rise homes! And try to bring a fragile product to the nearest Park in the crush of urban transport it is almost hopeless.
Everyone is used to what is required for forming the matrix and punch. In many cases, however, can do without the surround matrix — sufficient and shaped holes in sheet metal or plywood. But without the surround of the punch!..
