The MD500 series helicopter belongs to the category of light civilian and military multi-purpose helicopters, which can carry a maximum of four people. Developed in 500 from 1976, Boeing is now producing three different models. The series includes the MD500E, MD520N, and MD530F.The scale reproduction of this known helicopter is not inferior to the original and captivates optically by many small details such as rivets, indicated door frame, LED lighting and the 5-sheet rotor head made from aluminum. The swash plate and the main rotor shaft are also made of aluminum. Blade holder and linkages are made of high-strength plastic and allow free movement of all components without play. Hull and chassis of the helicopter are made of impact-resistant ABS-plastic, which considerably improves the durability of the material. Main and tail engines are designed as brushless motors generate enough power for powerful and dynamic flight maneuvers. The built-in gyro electronics stabilize the model in all positions and gives a secure flying feeling, which also inspires beginners. The flight behavior in hover flight is reminiscent of a coaxial helicopter. In normal flight, the system works like a speed or pitch-controlled helicopter. The auto-stabilization starts again immediately when the sticks of the remote control are put back in the central position. So there are no nasty surprises in the flight. This model also comes with our popular auto-start and auto-landing system at the touch of a button. Different flight phases (beginners, advanced, professional) can be switched at the transmitter, WAS leads to different servo deflections at the swash plate and thus changes the sensitivity of the model. The helicopter is also equipped with an Attitude Hold system (automatic lifting). The transmitter system works in the safe and interference-free 2.4 GHz band and the model is relatively little wind from the outside due to its power and size.This text is machine translated.
