Product overview
The HOBBYWING MFC 48x17.5 is a folding propeller for the propulsion systems of heavy-lift crop-protection UAVs. Its blades use carbon fiber and epoxy resin, while the propeller clamp uses aluminum alloy. A single blade weighs 117 g, and one propeller including its clamp weighs 416 g. The physical design combines an aerodynamic airfoil with tip winglets. Its reversible clamp mounting structure allows one clamp set to accommodate forward and reverse propeller installations.
For motor integration, the recommended pairing is the 11122-60KV. The optimal rotational speed range is 1700~2500 RPM, with a recommended maximum of 2900 RPM. Typical thrust is 8~ 32 kg, while limiting thrust is 43 kg; these are distinct operating figures for propulsion sizing. Ambient operating temperature spans -40~65 ℃. Storage requires -10~35 ℃ and humidity of ≤85%, giving the propeller a narrower temperature envelope in storage than during operation.
