Product overview
The HOBBYWING MSC 22x7.8 is a propulsion component intended for efficient UAV applications, including high-altitude use. Its matte ultra-light construction combines carbon fiber with epoxy resin, with a single weight of 36 g. The material offers high specific strength and stiffness, along with corrosion and fatigue resistance. An aerodynamic airfoil and blade-tip winglet shape delay airflow separation, supporting a stated blade-efficiency improvement of 3–5%. Low rotational inertia is another defining feature of the design.
Integration centers on the propulsion system, with improved power output associated with HOBBYWING H Series motors and their matching magnetic-circuit design. The optimal rotational-speed range is 2800–4500 r/min, while the commonly used pulling-force range is 2–5 kg; the separate ultimate pulling-force figure is 12 kg. Operating ambient temperature spans -30 to 50 °C. Storage requires a temperature of -10 to 35 °C and humidity of 60–90%, giving procurement teams distinct operating and storage limits.
