The M5 and M6 helicopters bridge the gap between the M4 MAX and M7, offering a versatile platform for everything from smooth cruising to aggressive 3D. With over 90% shared parts, a lightweight frame, and proven rotor and tail designs, they deliver reliable performance and easy maintenance. Built for adaptability and precision, M5 and M6 are ready for any flying style.
About the M5 550 Electric Helicopter
Frame
The M5 is built around a lightweight, rigid carbon fiber frame with chamfered lower panels and a CNC-machined aluminum main plate. It’s designed for 15mm servos and features integrated wiring paths, a modular servo rack, and quick-release latches for both the canopy and battery tray, making setup and maintenance simple and efficient.
Rotor & Tail System
Inspired by the M7, the M5’s rotor head uses a 12mm main shaft and 5mm ball joints for precise, responsive control. The tail system includes a compact, one-piece housing with a slop-free bell crank and a 6mm shaft, delivering dependable yaw authority through a 28mm carbon boom. Dynamic tail weights help reduce servo load in flight.
Drivetrain
The M5 uses a 115T main gear and supports a wide range of pinion options from 11 to 15 teeth, allowing flexible gearing for different flying styles. The motor mount rides on rails for perfect gear mesh every time. A large battery bay fits 6-12S packs, and the quick-release tray system is shared with the M6, offering easy swaps and compatibility.
