None of the types of modeling to the apparatus is not presented at the same time so many conflicting claims as to RC jumper gliders. Imagine that you need to design a machine that combines the properties of high-speed models, gliders-paritala and apparatus created specifically for ustanovlena of records range.
However, modelers safely solve such problems.
Long gone are the days when the competition marshalling of gliders could be seen only the usual RC priteli now hope to succeed with this model no. The modern representative of the class F3В — universal embodied experience of the creative search of many athletes. Its differences — speed and high aerodynamic efficiency, the ability to fly safely in strong wind and feel the weakest ascending thermal streams, gaining precious extra metres of altitude. The growing popularity of motocross class gliders is not only the widest possibilities of design search — there is another important factor. Gliders do not have the enormous overloads and vibrations as the motor model means, and the equipment can be used not so high-class and more available to the average athlete.
So, jumper RC glider-wagon. The number one issue for this kind of model — profile for the bearing surfaces. Recently, krossovki bolder refuse to use the well bearing profiles with strongly arched in the middle line. They came pretty thick, lenticular, which not only provides the high stiffness of the wings of the velocity model, but also excellent dynamic performance of the flight, its range. Modern means of towing (winch, petrol or electric) help to “highs” in the first of three exercises — for the duration of the flight — even in the absence of the ascending thermal streams. When performing other exercises that range and speed requirements to the supporting profile properties fade into the background. It is more important than minimal aerodynamic drag at angles of attack close to zero (more precisely, with insignificant coefficients of the lift force), which can not provide the supporting concave-convex profiles.
