New production version incorporates aerospace-grade AL7075-T6 materials and an innovative Mechanical Lock design for unprecedented performance and durability.

The new KDE Direct Heavy-Lift Propeller Blade Adapter (ML), Dual-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 hex jam-nuts and Belleville spring lock washers for a mechanical lock and 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.

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).
