Description

The HQProp 8×4.5R Slow Flyer Pusher Prop is engineered for applications requiring smooth, efficient thrust at lower rotational speeds. Its aerodynamic profile minimizes drag and noise, making it suitable for aerial photography platforms, long-endurance drones, and slow-flying multirotors where flight time and stability are prioritized over aggressive acrobatics.

The carbon fiber composite construction provides a high strength-to-weight ratio, ensuring durability against impacts while maintaining precise blade geometry for consistent performance. The included set of adapter rings allows for a secure fit on a wide range of brushless motor shaft sizes, enhancing its versatility across different builds.

Key Features

  • Optimized Slow-Fly Design: Blade geometry and pitch are tuned for high thrust efficiency at lower RPMs, extending flight time and reducing power consumption.
  • Carbon Fiber Composite Build: Offers excellent durability and resistance to flex, maintaining performance integrity and reducing harmonic vibrations.
  • Multi-Shaft Compatibility: Includes a full adapter ring set (6mm, 5mm, 4mm, 3mm) to fit motor shafts from 8mm to 9.5mm in diameter.
  • Precision-Molded Hub: Features a 14mm diameter, 7.5mm thick hub with reinforced structure for reliable torque transfer and mounting security.
  • Right-Hand Rotation (CW): Designed specifically for pusher applications or motors requiring clockwise rotation.
  • Low-Weight Design: At approximately 6.65 grams per propeller, it minimizes rotational mass for quicker motor response.

Applications

  • Slow-fly and long-endurance multirotor drones (e.g., aerial mapping, surveillance platforms).
  • FPV pusher configurations on fixed-wing aircraft or hybrid VTOL drones.
  • Cinematic drone builds prioritizing smooth, efficient flight over high-speed acrobatics.
  • Heavy-lift multirotors requiring efficient thrust at moderate RPMs.

Frequently Asked Questions

What motors are these 8x4.5R propellers compatible with?

These propellers are designed for brushless motors with shaft sizes of 8mm, 9.3mm, or 9.5mm. The included adapter ring set (6mm, 5mm, 4mm, 3mm) allows them to be securely mounted on a wider range of motor shafts by reducing the hub bore size as needed.

Are these propellers suitable for high-speed FPV racing?

No, the HQProp 8x4.5R is a slow-fly design optimized for efficiency and thrust at lower RPMs. It is best suited for cinematic flying, long-endurance platforms, or heavy-lift applications where smooth, efficient flight is more important than top speed and aggressive acrobatic performance.

What is the difference between a pusher propeller and a standard one?

A pusher propeller, like this 8x4.5R (CW), is designed to be mounted on the rear of an aircraft (like a fixed-wing or specific multirotor arm) to provide forward thrust. It has a right-hand (clockwise) rotation when viewed from the rear. Standard tractor props on multirotors typically have opposite rotation directions on alternating motors.
