Compatible with the KDE7215XF up to KDE10218XF Brushless Motors.

Compatible with the KDE-CF245-TP up to KDE-CF305-TP Propeller Blades.

(see Specifications and Technical Media for additional information)

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

Propeller Blades are installed in dual-matched sets of Triple-Propeller Blades to the Propeller Blade Adapters.  Matched-blades are installed at the 120° offset for correct balancing and smooth flight-operation (see Installation Diagram for more details).

The new KDE Direct Heavy-Lift Propeller Blade Adapter, Hex-Edition provides a professional-quality, CNC balanced folding-propeller assembly for the KDE Direct UAS Multi-Rotor Brushless Motor Series (and adaptable to other motors with quad- M3 x ф20 mm mounting threads) and KDE Direct UAS Carbon-Fiber Propeller Blade Series.  The upgrade includes Class 12.9 hardware for high-strength safety and utilizes M4 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

Models: Universal mounting pattern provides simple installation for a wide-range of multi-rotor and UAS applications: M3 x ф20 mm (4).
