Description

The KDEXF-PA620-LH propeller adapter is engineered for demanding commercial and industrial UAV platforms requiring reliable, high-torque propeller retention. Its M6 x 20mm left-hand thread is specifically designed for clockwise-spinning propellers, utilizing rotational force to tighten the connection, thereby preventing in-flight loosening.

Constructed from 7075-T6 aluminum and finished with precision CNC machining, the adapter achieves a high degree of concentricity and balance. This critical manufacturing tolerance directly translates to smoother motor operation, reduced harmonic vibrations, and improved overall flight performance and component longevity.

Key Features

Aerospace-grade 7075-T6 aluminum construction provides superior tensile strength and fatigue resistance.
CNC-machined to exacting tolerances for perfect static and dynamic balance, minimizing operational vibrations.
Left-hand (CW) thread ensures propellers self-tighten under normal motor rotation, enhancing flight safety.
Includes a versatile M8 adapter collar for compatibility with a wider range of motor shaft diameters.
Supplied with four high-strength Class 12.9 socket head cap screws for a secure, shear-resistant mount.
Low-maintenance design built for long service life in rigorous commercial UAS operations.
Direct compatibility with the entire KDE Direct XF series of high-performance multi-rotor motors.

Applications

Heavy-lift cinematography and industrial inspection drones utilizing KDE Direct XF-series motors.
Agricultural spraying UAVs requiring reliable, high-torque propeller mounting for sustained operation.
Commercial cargo delivery platforms where vibration reduction is critical for payload and avionics integrity.
High-performance multi-rotor racing or endurance platforms built with BHRC or compatible brushless motors.

Frequently Asked Questions

What is the purpose of the left-hand thread on this propeller adapter?

The left-hand (counter-clockwise) thread is designed for use on motors with a standard clockwise rotation. When installed on a clockwise-spinning propeller, the adapter will self-tighten during operation due to the opposing thread direction, preventing it from loosening in flight and enhancing safety.

Which KDE Direct motors is this adapter compatible with?

This adapter is directly compatible with the KDE Direct XF series of multi-rotor motors, including models like the KDE3520XF, KDE4014XF, KDE4215XF, KDE5215XF, KDE6213XF, and KDE6815XF. It is also specified for use with BHRC series motors. Always verify your motor's shaft diameter and threading before purchase.

What is included in the package, and what hardware is needed for installation?

The package includes the KDEXF-PA620-LH adapter itself, an M8 adapter collar for larger shaft diameters, and four high-strength Class 12.9 M3x8mm socket head cap screws. Installation requires fitting the adapter over the motor shaft, securing it with the provided screws through the collar, and then threading the propeller onto the M6 left-hand threads.
