The HQProp 9×4.5R is a 9-inch, 2-blade carbon fiber pusher propeller designed for multirotor applications requiring a clockwise (CW) rotation. This 2-pack is engineered for high-thrust, efficient flight on larger FPV and aerial photography platforms.

Features

  • 9-inch diameter with 4.5-inch pitch for high thrust and efficient lift.
  • Constructed from durable, lightweight carbon fiber composite material.
  • Clockwise (CW) rotation pusher prop for standard multirotor motor configurations.
  • Includes adapter ringsets for 6mm, 5mm, 4mm, and 3mm motor shafts.
  • Optimized for 5S-6S LiPo systems on large freestyle, cinematic, and heavy-lift drones.

Description

The HQProp 9×4.5R propeller is engineered for pilots seeking a balance of high static thrust and efficient forward flight on larger multirotor platforms. Its carbon fiber construction provides a superior strength-to-weight ratio, reducing flex under high torque loads for precise control and responsive handling.

Designed as a pusher prop with a clockwise rotation, it is ideal for standard motor setups on X-frame and H-frame drones. The 4.5-inch pitch offers a versatile performance profile, suitable for both aggressive freestyle maneuvers and stable aerial cinematography when paired with appropriate 400-500KV class motors.

Key Features

  • High-Quality Carbon Fiber Composite: Delivers exceptional durability and minimal blade flex for consistent performance.
  • Precision-Molded Hub: Features a 16mm diameter and 8.5mm thickness for secure mounting and vibration-free operation.
  • Comprehensive Adapter Kit: Includes rings for 6mm, 5mm, 4mm, and 3mm motor shafts, ensuring broad compatibility.
  • Aerodynamic Blade Design: Curved tips and optimized airfoil reduce noise and improve efficiency across the RPM range.
  • Dark Grey Finish: Provides a sleek, professional appearance with high visibility against various backgrounds.

Applications

  • Large 7-inch to 9-inch FPV freestyle and long-range drones requiring high thrust.
  • Aerial photography and cinematography platforms (e.g., heavy-lift hexacopters) for stable, efficient flight.
  • DIY multirotor builds using 400-600KV motors on 5S or 6S LiPo battery systems.
  • Racing gates and course practice where durable, replaceable props are needed for larger craft.

Frequently Asked Questions

What motor KV and battery voltage are these 9x4.5R props best suited for?

These props are optimized for lower KV motors (typically in the 400-600KV range) running on 5S or 6S LiPo batteries. This combination provides the necessary torque to efficiently spin the large 9-inch diameter while delivering high thrust for larger drones.

Do I need to use the included adapter rings, and how do they work?

Yes, if your motor shaft is smaller than the prop's 9.5mm, 8mm, or 6mm bore. The included plastic rings press into the propeller's hub to reduce the inner diameter, creating a snug, concentric fit on 6mm, 5mm, 4mm, or 3mm motor shafts, which is critical for balancing and vibration reduction.

Is this a 'pusher' or 'tractor' style propeller, and what's the difference?

This is a pusher propeller, designated by the 'R' (for Right-hand/Clockwise rotation). Pusher props are mounted on motors with the shaft facing upward, so they 'push' air downward. This is the standard configuration for most multirotor motors. Tractor props pull air and are typically used on the front of fixed-wing aircraft.
