Description

The Pro-Range 1220 propellers are engineered for micro and nano-class drones, where weight and precise thrust control are critical. The 31mm diameter and 4-blade configuration offer a high disc area for improved low-speed lift and stability, while the 2-inch pitch optimizes efficiency for agile flight maneuvers.

Manufactured from injection-molded polycarbonate, these blades achieve an optimal balance between structural rigidity and minimal mass. This construction resists deformation at high RPMs, ensuring consistent performance and reducing vibration for smoother video footage. The 1mm bore is precisely sized for secure mounting on common micro motor shafts.

Key Features

Four-blade aerodynamic profile enhances low-speed thrust and flight stability.
Polycarbonate material provides high impact resistance and fatigue strength.
Precision-molded hub with 1mm bore ensures a secure, concentric fit on motor shafts.
Balanced blade design from the factory minimizes the need for post-installation balancing.
Vibrant Clear Yellow finish aids in propeller orientation during assembly and in-flight identification.
Optimized for lightweight builds where every gram of thrust efficiency matters.

Applications

Ultra-lightweight 65mm to 75mm brushed or brushless micro FPV whoop drones.
TinyWhoop-style indoor racing and freestyle builds using 0703 or similar 1mm-shaft motors.
Nano-scale DIY drone projects and educational platforms requiring precise, low-inertia propellers.
Lightweight payload carriers and micro aerial photography platforms where smooth flight is essential.

Frequently Asked Questions

What motor shaft size are these Pro-Range 1220 propellers designed for?

These propellers are designed for a 1mm motor shaft bore. They are specifically compatible with micro motors such as the 0703 coreless motor series and other brushed or brushless motors utilizing a 1mm diameter shaft. Ensure your motor shaft matches this dimension for a secure, vibration-free fit.

What is the recommended application for these 31mm propellers?

The 31mm diameter and 4-blade design make these propellers ideal for ultra-lightweight micro and nano drones, typically in the 65mm to 75mm frame size class. They are perfect for TinyWhoop-style indoor FPV builds, providing the necessary thrust and stability for agile flying while keeping weight to a minimum.

Are these propellers pre-balanced, and what material are they made from?

These propellers are precision-molded from polycarbonate (PC), a material chosen for its excellent strength-to-weight ratio and impact resistance. While they are manufactured to high tolerances for good initial balance, as with all propellers, final dynamic balancing after installation is recommended for the smoothest possible flight performance, especially on sensitive micro camera platforms.
