Compatible with the KDE-DPA-ML-M4 Dual-Propeller Blade Adapter (ML) Series.

New production version has increased the propeller screw size from M3 to M4

The new KDE Direct Carbon-Fiber Propeller Blades are constructed of true carbon-fiber 3K materials - same as we supply to our military-customers, and now available for commercial and industrial applications.  All propellers are dynamically-balanced and provided in matched-pairs, so simply install the blades and go fly - no need for secondary balancing or other headaches that plague competitive offerings.  The Propeller Blade Series is designed for simple installation to the KDE Direct UAS Multi-Rotor Propeller Blade Adapters and UAS Multi-Rotor Brushless Motor Series, for unprecedented smoothness and efficient flight performance.

Note: propeller blades are dynamically-balanced matched pairs, for smooth and vibration-free flight operation.  Blades cannot be intermixed between pairs - make sure to keep organized as matched blades to prevent balance-related concerns.  If a single-blade is damaged during operation, make sure to replace the propeller blade pair (CW or CCW).
