HQProp 15×8.5×3 Propeller — Black Glass Fiber Reinforced Nylon (1CW+1CCW)

The HQProp 15x8.5x3 is a heavy-duty tri-blade propeller engineered for X-Class builds, heavy-lift cinelifters, and large commercial drone platforms. Moulded from glass-fiber-reinforced nylon, these massive 15-inch props provide exceptional stiffness to handle the immense torque of large-stator motors without flattening out or fluttering under heavy payloads.

Key features

• 15-inch diameter and aggressive 8.5-inch pitch yield massive thrust for lifting heavy cinema cameras or agricultural payloads.
• Glass-fiber-reinforced nylon construction maintains blade profile and stability under extreme aerodynamic loads.
• Tri-blade design offers a smoother flight feel and better grip in the air compared to traditional bi-blades of this size.
• Includes a perfectly matched clockwise and counter-clockwise pair.
