OMPHobby M4 Helicopter – Blue Kit
The OMPHobby M4 Blue Kit is a premium 385mm class RC helicopter engineered for pilots looking for a lightweight, precise, and highly capable platform with the freedom to choose their own electronics package. Designed by Jonas Wackershauser, the M4 combines modern engineering, excellent visibility, and outstanding flight performance into a compact yet powerful helicopter platform.
Unlike the PNP version, the Kit version includes the helicopter airframe, main motor, and rotor blades, allowing builders to fully customize their ESC, servos, flybarless system, receiver, and battery setup to match their flying style and preferred electronics ecosystem.
The M4 features a rigid carbon fiber frame design, belt-driven tail system, optimized geometry, and large battery compartment for excellent balance and easy maintenance. Whether you're into smooth sport flying, precision aerobatics, or aggressive 3D, the M4 delivers exceptional control, durability, and flight feel in a compact package.
