Details

Hobbywing HF 57 Propeller uses high-strength carbon fiber for durability, corrosion resistance, and optimal efficiency in harsh conditions.

Lightweight design for optimal agility. Mass near shaft reduces inertia, enhancing response. Narrow wing profile shortens length, lowering weight and boosting efficiency. Thin walls minimize material use without compromising stiffness.

Aerodynamic black technology boosts efficiency. Unique airfoil and winglet design reduce drag, delay airflow separation, enhancing propeller performance by 3%-5%. HW 5720 CCW model featured.

Hobbywing HF 57 Propeller excels in diverse environments. Made with imported carbon fiber, it resists corrosion and deformation. It performs reliably in extreme temperatures—staying stable in high heat and dependable in cold conditions. It also handles windy, rocky terrains effectively. Ideal for mountain lifting, outdoor transport, and emergency rescue, this propeller ensures safety and uninterrupted operation in challenging scenarios.

Strict quality control ensures consistent propeller performance, leading to smoother flights for users.

Innovative dual-mode drive with efficient switching. Self-developed blade clamp technology and reversible blade structure support quick coaxial twin-rotor system changes, reducing costs and increasing maintenance efficiency. Blades must be replaced in pairs.

Gold power combo boosts efficiency. Hobbywing motor with optimized magnetic circuit design ensures constant torque in complex airflow, excelling in heavy-load takeoff and landing performance.
