Description

The HQProp J75 series propellers are engineered for pilots seeking reliable thrust and predictable handling from their 5-inch and 7-inch FPV builds. The 7x5x3 configuration—7-inch diameter, 5-inch pitch, and three blades—delivers a strong thrust curve while maintaining manageable current draw on compatible 2207 to 2806.5 size brushless motors.

Manufactured from high-grade polycarbonate, these propellers offer a favorable stiffness-to-weight ratio, resisting deformation at high RPMs and providing consistent performance across aggressive freestyle maneuvers and extended cruising flights. The light grey color aids in visibility and orientation during flight.

Key Features

  • Polycarbonate Durability: Offers high impact resistance and fatigue strength for extended propeller life and consistent flight characteristics.
  • Triblade Aerodynamics: Three-blade design provides an optimal balance of thrust, efficiency, and acoustic signature for freestyle and cruising.
  • Precision-Molded Hub: Features a 14mm diameter hub with a true 5mm bore for secure, concentric mounting on standard motor shafts.
  • Performance-Tuned Pitch: The 5-inch pitch is calibrated for responsive acceleration and stable top-end speed on 4S to 6S LiPo systems.
  • Matched Set: Each pack includes two clockwise (CW) and two counter-clockwise (CCW) propellers, factory-balanced for smooth operation.

Applications

  • 7-inch long-range and endurance FPV drone builds requiring efficient thrust.
  • Heavy-lift 5-inch freestyle and cinematic drones needing additional propulsive authority.
  • Large-scale multirotor platforms and experimental aircraft where 7-inch propellers are specified.
  • Transitional builds bridging 5-inch and 7-inch frame sizes for customized performance tuning.

Frequently Asked Questions

What size motors are compatible with the HQProp J75 7x5x3 propellers?

These propellers are designed for motors with a standard 5mm output shaft, typically found on 2207, 2306, and larger 2806.5 size motors used in 5-inch and 7-inch drone builds. Ensure your motor's KV rating and battery voltage (commonly 4S to 6S) are suitable for the 7-inch diameter and 5-inch pitch to avoid over-current conditions.

Are these propellers suitable for high-speed FPV racing?

While the J75 provides strong thrust, its 7-inch diameter is more common in long-range and freestyle applications than dedicated racing. The 5-inch pitch offers good acceleration, but the larger disk area may limit ultimate top speed compared to smaller, higher-pitched racing props on typical 5-inch race frames. They are excellent for aggressive freestyle and endurance flying.

Do I need propeller adapter rings to mount these?

No. The HQProp J75 propellers feature a solid 5mm bore and do not include or require separate adapter rings. They mount directly onto motor shafts with a 5mm diameter. Always use a proper propeller nut and washer, and ensure the shaft is clean and undamaged for a secure fit.
