Description

The DPAHL-ML adapter is engineered as a critical interface between high-power brushless motors and folding propeller blades in heavy-lift UAV systems. Its dual-edition design and aerospace-grade AL7075-T6 construction provide the structural integrity needed to withstand the high torque and thrust loads generated during aggressive maneuvers and payload carriage.

The integrated mechanical lock system, utilizing M4 CubePilot jam-nuts and Belleville washers, ensures propeller blades remain securely fastened, preventing slippage and maintaining consistent pitch alignment. This precision-machined component is balanced to minimize harmonic vibrations, which protects motor bearings and flight controller sensors, leading to more stable flight and clearer FPV video feed.

Key Features

  • Aerospace-Grade Build: Machined from AL7075-T6 aluminum, offering an optimal strength-to-weight ratio for demanding UAV operations.
  • Secure Mechanical Lock: Proprietary M4 jam-nut and Belleville washer system provides a vibration-resistant, consistent clamping force on propeller blades.
  • Precision CNC Balancing: The entire hub assembly is machined and balanced to reduce rotational mass imbalances, enhancing motor efficiency and flight smoothness.
  • Broad Motor Compatibility: Designed for the KDE Direct UAS motor series and any motor with a standard quad-M3 x 20mm (M3x20) mounting pattern.
  • Optimized for Carbon Blades: Engineered specifically for use with KDE Direct's high-performance UAS carbon-fiber propeller blades.
  • High-Strength Fasteners: Includes Class 12.9 socket head shoulder cap screws for maximum clamping security and shear strength.
  • Low-Maintenance Design: The reliable lock system minimizes the need for frequent re-tightening or adjustments between flight sessions.

Applications

  • Heavy-lift multi-rotor drones for agricultural spraying, surveying, or cargo delivery.
  • Professional cinematography UAVs requiring smooth, vibration-free operation with large-diameter folding propellers.
  • Industrial inspection drones where reliable, low-maintenance propulsion is critical.
  • Custom UAS builds utilizing KDE Direct UAS series brushless motors and carbon-fiber propeller blades.

Frequently Asked Questions

What motors is the DPAHL-ML adapter compatible with?

The adapter is designed for KDE Direct UAS Multi-Rotor Brushless Motor Series. It is also compatible with any other brushless motor that uses the standard quad-M3 x 20mm mounting hole pattern, making it versatile for various professional-grade UAV builds.

How does the mechanical lock system work to secure the propeller blades?

The system uses M4 CubePilot jam-nuts combined with Belleville spring lock washers. When tightened, the Belleville washers apply a consistent spring force that resists loosening from vibration, ensuring the propeller blades remain securely clamped to the hub during high-torque operation.

Can this adapter be used with non-KDE propeller blades?

It is engineered and optimized specifically for use with KDE Direct UAS Carbon-Fiber Propeller Blades. Using it with blades from other manufacturers is not recommended, as the blade root dimensions, clamping interface, and performance characteristics may not match, potentially compromising safety and flight performance.
