Description

The HQProp 9×4.7R Slow Flyer Pusher Prop is engineered for multirotor applications prioritizing flight efficiency and stability over raw thrust. Its 9-inch diameter and 4.7-inch pitch generate substantial lift at lower rotational speeds, reducing power consumption and extending flight times. The carbon fiber construction ensures blade rigidity, minimizing flex and maintaining precise aerodynamic performance under load.

Designed specifically for pusher configurations, this CW propeller is ideal for builds where motor direction is fixed or for creating matched pairs on coaxial setups. The included multi-size adapter ringset provides secure mounting on a wide range of motor shafts, from 3mm to 6mm, ensuring compatibility with many popular slow-fly and mapping-focused motor models.

Key Features

  • High-Efficiency Aerodynamics: The 9x4.7R slow-fly profile is optimized for maximum thrust per watt, ideal for long-endurance flight missions.
  • Carbon Fiber Durability: Manufactured from a resilient carbon fiber composite, offering excellent impact resistance and fatigue life compared to standard plastics.
  • Pusher Configuration Ready: Supplied as a 2-pack of clockwise (CW) propellers, specifically for drone builds utilizing pusher-style motor layouts.
  • Universal Mounting Kit: Comes with a full adapter ringset (6/5/4/3mm) for secure attachment to virtually any standard brushless motor shaft.
  • Precision Balanced: HQProp's manufacturing process ensures minimal inherent vibration, contributing to smoother video footage and reduced frame stress.
  • Dark Grey Finish: Provides a professional, non-reflective aesthetic that reduces glare in various lighting conditions.

Applications

  • Aerial photography and mapping drones (e.g., 450-550mm frame size) requiring efficient, stable flight for camera gimbal work.
  • Long-range FPV cruisers built for endurance, where low KV motors are paired with high-pitch, large-diameter props.
  • Heavy-lift multirotors and agricultural drones where efficient thrust generation is critical for payload capacity.
  • Coaxial drone designs requiring matched pairs of CW and CCW propellers on stacked motors.
  • DIY experimental aircraft and VTOL platforms utilizing pusher propeller configurations for forward thrust.

Frequently Asked Questions

What type of drone builds are these 9x4.7R propellers best suited for?

These propellers are optimized for slow-fly, high-efficiency applications. They are ideal for larger aerial photography platforms (450-550mm frames), long-range FPV cruisers, and heavy-lift multirotors where maximizing flight time and stable thrust is more important than peak racing performance.

What does 'Pusher Prop' and the 'R' designation mean?

'Pusher Prop' indicates this propeller is intended for a motor configuration where it pushes the aircraft forward. The 'R' suffix denotes Right-hand rotation, which is equivalent to Clockwise (CW) rotation when viewed from the front of the propeller (motor shaft facing you).

Are the included adapter rings necessary for installation?

Yes, the adapter rings are essential for a secure, concentric fit on your motor shaft. The set includes rings for 3mm, 4mm, 5mm, and 6mm shafts. Select the ring that matches your motor's shaft diameter to eliminate wobble and ensure safe operation.

Can I use these on high-KV racing motors?

It is not recommended. The 9x4.7R is a large, high-pitch propeller designed for low to mid-KV motors operating at moderate RPMs. Using it on a high-KV racing motor would likely overload the ESC and motor, causing excessive heat, reduced efficiency, and potential component failure.
