OMP M1 Evo - A fully functional 3D helicopter in a mini format with a rotor diameter of just 290 mm. Direct drive and two brushless motors. Carbon fiber frame with a central aluminum backbone. Flight controller with connections for S-Bus or DSMX satellite receivers. Adjustable parameters, including gyro sensitivity, rates, gain, and servo center position. Suitable for indoor or outdoor flights (in calm conditions). Includes a 2S 350 mAh LiPo battery. Pitch-controlled helicopters typically maintain the same rotor speed. To ascend or descend, the angle of attack of the rotor blades is adjusted. The advantage of this method is that the helicopter responds without delays, allowing for advanced aerobatic and 3D maneuvers, but it requires certain skills. Therefore, pitch-controlled models are primarily suited for professional pilots. BNF - Bind and Fly. The advantage of Bind and Fly models is that they come pre-assembled and wired. Since a receiver is already integrated, these models only need to be bound to a compatible remote control. Brushless motor. A brushless motor is an electric motor without brushes, characterized by higher efficiency, lower wear, and lighter weight compared to brushed motors. Difficulty level: Advanced. You possess basic knowledge and have the necessary experience and suitable tools to correctly wire your model if needed and operate it safely.
