The Pro-Range 1220 is a set of 31mm diameter, 4-blade propellers with a 2-inch pitch, designed for micro and nano drones utilizing coreless motors like the 0703. Constructed from durable polycarbonate, they provide a high thrust-to-weight ratio for stable and efficient flight in compact FPV and indoor drone applications.

Features

  • 31mm diameter, 4-blade design with a 2-inch pitch for high thrust in micro drones.
  • Constructed from durable, lightweight polycarbonate (PC) material.
  • 0.8mm center hole diameter compatible with coreless motors like 0703.
  • Includes 4 clockwise (CW) and 4 counter-clockwise (CCW) propellers for a complete set.
  • Clear Purple finish for visual distinction and style.

Description

The Pro-Range 1220 propellers are engineered for the demanding requirements of micro and nano-sized drones. The 31mm diameter and 4-blade configuration, combined with a 2-inch pitch, are optimized to generate significant thrust from small coreless motors, improving the agility and punch-out performance of lightweight builds.

Made from injection-molded polycarbonate, these blades achieve an optimal balance between rigidity and weight, resisting deformation at high RPMs while minimizing rotational mass. This material choice ensures consistent performance and durability for indoor FPV racing and precise aerial photography with micro platforms.

Key Features

  • Micro-Drone Optimized: 31mm diameter and 4-blade design delivers high thrust density for 65mm to 75mm whoop and toothpick-style drones.
  • Polycarbonate Durability: Offers high impact resistance and fatigue strength for repeated flights and minor crashes.
  • Precision Balanced: Manufactured to tight tolerances for smooth operation, reducing motor vibration and improving flight stability.
  • Coreless Motor Compatibility: 0.8mm center hole is standard for 0703, 0802, and similar micro brushless and coreless motor shafts.
  • Complete Flight Set: Package includes four matched pairs (4CW+4CCW) for immediate installation and spares.

Applications

  • Ultra-micro and nano FPV drones (65mm-75mm frame size).
  • Indoor whoop and TinyWhoop-style quadcopters.
  • Lightweight micro drones for cinematic indoor footage.
  • DIY micro drone builds utilizing 0703 or 0802 coreless motors.
  • Educational and prototyping platforms for micro aerial vehicles.

Frequently Asked Questions

What size motors are these Pro-Range 1220 propellers compatible with?

These propellers are designed for micro coreless motors, specifically those with a 0.8mm shaft diameter such as the 0703 and 0802 motor sizes. They are not suitable for standard brushless motors with larger mounting patterns (e.g., M5 threads). Always verify your motor's shaft diameter before installation.

What is the advantage of a 4-blade design on such a small propeller?

A 4-blade design on a 31mm propeller increases the total blade area, which generates more thrust at a given RPM compared to a 2-blade prop. This is crucial for micro drones with limited motor power, as it improves low-speed control, punch-out acceleration, and overall flight stability in confined indoor spaces.

Are these propellers pre-balanced?

Pro-Range propellers are manufactured to consistent tolerances, offering good inherent balance for smooth operation on micro motors. However, for optimal performance in high-RPM applications or to eliminate all vibration, manual balancing with a prop balancer designed for micro props is recommended.
