Description

Engineered for 7-inch drone platforms, the HQProp 7X3.5X3 propeller utilizes a three-blade geometry to deliver a compelling mix of static thrust and in-flight efficiency. The 3.5-inch pitch is calibrated to provide strong pull without excessive current draw, making it suitable for long-range, freestyle, and heavy-lift applications where flight time and power are both priorities.

The propellers are molded from high-grade polycarbonate, a material chosen for its excellent fatigue resistance and ability to withstand minor impacts. This construction ensures consistent performance and dimensional stability across a wide range of RPMs and temperatures, maintaining precise balance for smooth, vibration-free operation.

Key Features

High-Efficiency Triblade Profile: The 3-blade design optimizes the thrust-to-power ratio, offering superior acceleration and top-end speed compared to many 2-blade designs while remaining smoother than 4 or 5-blade props.
Durable Polycarbonate Construction: Provides high strength-to-weight ratio and excellent resistance to cracking or deformation under load, ensuring longevity and consistent performance.
Precision Balanced Manufacturing: Each propeller is manufactured to tight tolerances for minimal inherent vibration, contributing to smoother video footage and reduced motor wear.
Wide Compatibility: The 5mm shaft bore and standard hub design ensure compatibility with the vast majority of 7-inch drone motor sizes, including 2507, 2806.5, and 2808 variants.
Light Grey Finish: Offers a neutral, professional appearance with high visibility against various backgrounds during flight.

Applications

7-inch Long-Range FPV Drones: Ideal for maximizing flight efficiency and cruise performance on 4S-6S setups.
7-inch Freestyle and Cinematic Drones: Provides the responsive thrust and control needed for aggressive maneuvers and smooth camera movements.
Heavy-Lift and Payload-Carrying Multirotors: The 7x3.5x3 configuration offers a strong lift capacity suitable for aerial photography rigs or light payload delivery.
DIY 7-inch Racing Drone Builds: A versatile prop choice for pilots tuning for a balance between straight-line speed and cornering agility on larger tracks.

Frequently Asked Questions

What is the recommended motor KV and battery voltage for these 7x3.5x3 propellers?

These propellers are well-suited for medium-to-high KV motors (e.g., 1300KV-1800KV) on 4S LiPo batteries for balanced performance, or lower KV motors (e.g., 800KV-1100KV) on 6S LiPo for high-efficiency, long-range flight. Always check your motor's maximum current rating to ensure compatibility with the prop load.

Do these HQProp 7x3.5x3 props require any adapter rings for installation?

No, adapter rings are not included and are typically not required. These props feature a standard 5mm bore designed to fit directly onto motor shafts with a 5mm diameter. Ensure your motor shaft uses an M5 thread nut or a compatible locking mechanism to secure the propeller.

Are these propellers balanced out of the package, and should I balance them before use?

HQProp propellers are manufactured to good tolerances and are often flyable without balancing. However, for the smoothest possible performance, especially on high-performance or cinematic builds, it is recommended to dynamically balance the propellers using a prop balancer to eliminate any minor vibrations that can affect flight stability and video quality.
