The 76mm High-Efficiency Propeller Pair is specifically engineered to extract maximum thrust from large coreless motors. At Electrapac, we recommend these propellers for "Heavy-Lift" micro drones and high-speed mini fans where a standard 55mm blade simply doesn't provide enough surface area for the motor's torque.

Product Overview

These propellers are designed with a wide-blade geometry to perfectly match the power curves of 1020 and 8520 coreless motors. Because larger motors have more internal torque, these 76mm blades allow your aircraft to generate more lift at lower RPMs, leading to smoother flight and better battery efficiency.

Key Features for Electrapac Customers

• Optimized Thrust Profile: The 76mm span provides a significantly larger "disc area" compared to standard micro propellers, making them ideal for carrying micro FPV cameras or larger 1S batteries.

• Tough & Flexible: Constructed from high-impact plastic that can survive minor crashes into walls or grass without snapping, saving you from constant replacements.

• Precision Press-Fit: Designed with a 1.0mm/1.2mm center hole that grips the motor shaft tightly, ensuring the propeller doesn't fly off during high-throttle maneuvers.

• Color-Coded Pairs: Comes as a matched set (one clockwise, one counter-clockwise) to ensure your Electrapac drone build is balanced and flight-ready.

• Low Noise Design: The aerodynamic tip profile is designed to reduce air turbulence, resulting in a quieter flight and less high-frequency vibration for your gyro.

Installation & Pro-Tips

To ensure your Electrapac propulsion system stays reliable, follow these installation guidelines:

1. Check Rotation: Look at the blade pitch before installing.

   • CW Motor (Red/Blue wires): Needs the Clockwise propeller.

   • CCW Motor (Black/White wires): Needs the Counter-Clockwise propeller.

2. The "Safety Pinch": When pushing the propeller onto the shaft, always support the bottom of the motor with your thumb. Never push the propeller against a hard surface, as this can force the motor shaft through the bottom plastic cap and ruin the motor.

3. Balance Check: If you notice excessive "jello" in your FPV video, check for small burrs on the propeller edges from a previous landing and sand them down lightly.

Primary Applications

• Large Micro Quads: The preferred propeller for 100mm–120mm brushed frames.

• DIY Mini Fans: Creating powerful, battery-operated handheld cooling fans.

• Science Projects: Building high-lift hovercraft or air-powered cars.

• RC Gliders: Use a single 76mm propeller for lightweight "pusher" style foam airplanes.
