In order to learn how rc helicopters started, it cannot hurt to learn interesting helicopter facts. In ancient China the children played with a flying spin, rising to rotate his hands. This was perhaps the oldest ancestor of modern helicopters, but it was not until 1906 when the man got up on the ground in a helicopter. The first man was Paul Cornu. Juan de la Cierva also contributed to the development of helicopters. But the story does not end here the helicopter, and if you want to know more about it and its inventor. Many manufacturers started to focus on mini scale helis. This is when rc helicopters origin came to the scene. Types of helicopters and helicopters models abound. Radio control is a new technology, which is bringing amazing benefits. Helicopters are a very versatile aircraft that have numerous applications in both civil and military. People who collect rc models are often fans of real helicopters.Settings blade pitch-gas engine specifics are outstanding. The main and fundamental to understand how an aircraft work is the fit between the blades pitch and gas engine. To create a lift capable of lifting your rc helicopter, you need the rotor blades have some positive degrees, not far from 0 °. What grades do you have to give to the blades to begin lifting the rc heli from the ground? The answer is very variable and it fully depends on the revolutions that it may have at that time. To begin the first attempts to control the helicopter and especially in the case of beginners, the recommended speed ranging around about 1,400 rpm, and the first thing you must try is to keep rc helicopters hovering at least with the maximum stability as possible. At lower rpm, angle of attack would be too big, with lots of air resistance and also have low inertia blades to provide adequate stability. On the contrary, if you had more speed, control responses would be too fast to begin with. Considering these 1400 revolutions per minute as suitable at this time, it must be a requirement that the rc helicopter must be kept constant in all the flight changes, whether the helicopter is still on the ground, at the time of takeoff, or when it is going through the phase of translation. As the ascent and descent of rc helicopters, they do not have to rely on more or less speed to the blades, but to vary the angle of attack of the same, always keeping the same circles.
