75mm 7.5cm Reverse Paddle Aircraft Propeller Blades with 1.2mm Shaft Hole For Coreless Motor Helicopter Toys Quadcopter RC Spare Parts Accessories 2 Pair (4 Pcs)

Building your own micro-drone, repairing a favorite RC helicopter, or designing a custom aerodynamic project? The right propellers make all the difference in achieving stable flight and maximizing motor thrust. These 75mm reverse paddle aircraft propeller blades are engineered specifically to handle the high RPMs of coreless motors.
When constructing DIY quadcopters, balancing lift and power consumption is crucial. These blades are designed to provide maximum aerodynamic efficiency without overloading your mini motors. This set includes four contrasting blades (Two red, Two black). This color distinction isn’t just for looks—it is highly practical for makers, allowing you to easily identify the front and rear orientation of your drone during rapid flight maneuvers.
With a precise 1.2mm shaft hole, they offer a secure, press-fit installation that won’t slip mid-air, making them an essential spare part for any electronics maker’s toolkit.

Features

1. Optimized for Coreless Motors: Engineered with an aerodynamic pitch that delivers excellent lift, thrust, and battery efficiency for DIY micro drones, RC helicopters, and airplane builds.
2. Precision Fit: Features an exact 1.2mm shaft hole for a tight friction fit, ensuring the blades stay securely attached to standard high-speed mini motors even at maximum throttle.
3. Reverse Paddle Design: Specifically shaped for multi-rotor stability, providing the necessary directional thrust required for agile quadcopter maneuvers.
4. High-Visibility Flight Tracking: The package includes Two red and Two black propeller, helping pilots easily track their aircraft’s heading and orientation from a distance.
5. Flexible & Crash-Resistant: Crafted from lightweight, durable plastic that can absorb the impact of minor crashes and bumps without easily snapping, extending the lifespan of your RC projects.
6. Perfect Dimensions: The 75mm (7.5cm) total length hits the sweet spot for balancing speed and torque in compact, lightweight DIY electronic models.
