Description

The HQProp Ultralight Whoop 31MMX3 propeller is a specialized component for the micro FPV drone segment. Its 31mm diameter and tri-blade configuration are calculated to deliver a high thrust-to-weight ratio while maintaining manageable amp draw on small 1S and 2S LiPo batteries. The polycarbonate material offers a resilient yet lightweight structure capable of withstanding the high-RPM demands and minor impacts typical of Whoop flight.

Designed with a 1.2×1.1×3 aerodynamic profile, this propeller generates sufficient lift for acrobatic maneuvers and punch-outs while preserving flight time. The 1mm shaft bore is a standard for 0702 to 0802 brushless motor sizes, ensuring a direct, secure fit without the need for adapter rings. This set is essential for pilots seeking to maximize the performance of their Tiny Whoop, Mobula6/7, or similar micro FPV platforms.

Key Features

Ultralight Polycarbonate Build: Engineered for minimal weight to reduce rotational inertia, enabling faster motor acceleration and more agile flight characteristics.
Optimized Whoop Aerodynamics: The 31mm diameter and specific pitch profile are tuned for the ducted airflow of Whoop frames, enhancing thrust efficiency within confined spaces.
Precision 1mm Hub: Features a true 1.0mm bore for a direct press-fit installation on standard micro motor shafts, eliminating play and vibration.
Durable Tri-Blade Design: Three-blade configuration provides a favorable balance of grip, stability, and top-end speed for technical flying.
Matched Rotation Set: Package includes a balanced pair of CW and CCW propellers for ready installation on any standard micro quadcopter.
High-RPM Capable: The material and hub design are validated for sustained high-RPM operation on aggressive 2S setups.

Applications

1S-2S Micro FPV Whoop Drones (e.g., BetaFPV Meteor65/75, HappyModel Mobula6/7, Tiny Whoop).
Indoor and Light Outdoor Acro/Freestyle Micro Quadcopters.
Ultralight DIY Micro Drone Builds utilizing 0702, 0802, or similar brushless motors.
FPV Racing in Confined Spaces where ducted propeller designs are mandatory.
Low-Weight Cinematic Micro Drones for smooth, efficient flight.
