OMP M4 Flybarless 3D Heli in the 380 class. Large, powerful direct drive brushless motor. Kit includes motor, controller, and four servos. Tail with belt drive 4.5:1. Compact chassis design. Large pitch ranges possible ±14°. Recommended battery: 6S 1800 - 2200 mAh LiPo. The OMP M4 features unique characteristics aimed at making it a perfectly flying and easy-to-maintain helicopter in the 380 class. PNP - Plug and Play. These models are almost flight-ready configured. Motor, controller, and servos are already mounted and wired. Unlike RTF models, you will need additional accessories before the model is ready for use. Pitch-controlled helicopters typically operate at a constant 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 delay. This allows for demanding aerobatic and 3D maneuvers but requires certain knowledge. Therefore, pitch-controlled models are mainly suitable for professional pilots. A brushless motor is an electric motor without brushes, which, compared to brushed motors, is characterized by higher efficiency, lower wear, and reduced weight. Skill level: Advanced. You possess basic knowledge and have the necessary experience and appropriate tools to correctly wire your model if needed and safely operate it.
