How to fly model airplanes
After the successful flight of the vehicle transporting the man made by the Wright brothers, interest in the spread of aviation rapidly and many models have been made. Model airplane enthusiasts are already in the 1900s. Most models are rubber powered, weaving a float with fuselage stick that are common in Europe. But even the first days of the flight model, gasoline and small compressed air engines are already used. The materials used in construction model are strips of birch veneer, spruce, piano wire or bamboo and oiled silk covering.
Then, the structure of balsa wood and tissue covering the United States appeared in the 1920s. So much for the history of model airplanes. So you see, even today, the structure of the aircraft and how to fly is no different from what we fly today. The wings, fuselage, vertical and horizontal stabilizers, propellers, engines, landing gear are the same. The plane, flying and in control during the flight that uses them. The wings are obviously officials why the aircraft can stay airborne for a long period. With proper design of the aircraft, size, considerations weight and aerodynamic characteristics, it will fly successfully. The aerodynamic principles behind what really makes it fly. But even if has a good design, weight and balance plays a major role. There was a saying "a bird feather better than a brick" that is true, because a very heavy airplane will not fly if it can not be sustained by its power plant (engine, fuel tank of the propeller, and). And in relation to balancing, a properly balanced air is controllable in flight. Usually, the fulcrum or center of gravity is quarter of the chord of the wing. Balancing, it is by placing your fingers on both sides of the wing, then move the receiver, batteries and servos the aircraft is balanced.
You may ask why the center of gravity is one fourth of the chord of the wing? It has something to do with the aerodynamic center, the neutral point can be explained in detail with some illustrations by following the link on the bottom.
When you look cross section of the wing shape is called a wing. Primarily composed of the wing upper and lower camber, attack and board leak. When the aircraft is in flight, there are aerodynamic forces that interact with the wings, vertical and horizontal stabilizers, as the plane goes against air or commonly called "relative wind". Then it creates a pressure difference on the upper versus the lower camber of the wing (Or the wing itself) that generates lift. The air that has passed the lower camber must have a higher pressure against the arch than to continue the flight. This has something to do with the law of continuity. The molecules of air that separates the leading edge, is greater and lower camber, should meet at the trailing edge at the same time. Since the upper curve has a greater curvature of the lower camber, distance on the upper arch is longer and therefore require more speed to meet the air on the lower camber. This creates pressure below the upper curve based on Bernoulli's principle "as the air velocity increases the pressure decreases,
Hope my brief explanation is understandable. If you want to know the details with the visual aids on the theory of model airplane flight I suggest going to my site:
