New production version incorporates aerospace-grade AL7075-T6 materials and updated, FEA-optimized geometry for improved strength and durability.


The new KDE Direct Propeller Blade Adapter, Dual-Edition provides a professional-quality, CNC balanced folding-propeller assembly for the KDE Direct XF Multi-Rotor Brushless Motor Series (and adaptable to other motors with dual- and quad- M3 x ф12 mm mounting threads) and KDE Direct Carbon-Fiber Propeller Blade Series.  The upgrade includes Class 12.9 hardware for high-strength safety and utilizes M3 nylon-insert locknuts to maintain consistent hold to the included custom CNC-machined, Socket Head Shoulder Cap Screws; reducing the need to readjust blade pressure and requiring minimal maintenance to the assembly between flights (Loctite optional for consistent blade pressure).



Material: Aluminum 7075-T6, Class 12.9 Alloy Steel
