KDE Direct motors use market leading technology


KDE Direct motor bearings feature triple or quad, ABEC-7 rated, Japanese NMB and/or NSK radial or angular-contact bearings with a rated bearing life span of 200 hours. The temperature of the bearings is rated up to 350°F. KDE Direct motors have smooth operation and industry-leading performance.

The motor bell assembly features a universal mounting pattern for drop-in propeller installation with an internal centrifugal fan that is used to expel heat out of the motor through convective cooling. Balancing epoxy is applied to the inside of the motor bell with craftsmanship and a shaft retaining collar is added to mechanically secure the rotor. A steel magnetic housing is bolted to the motor bell to prevent flux loss and curved N45UH Neodymium sintered-magnets are used for high efficiency and maximum power output.

The stator construction uses Japanese 0.2mm thick silicone steel laminations and powder coated wiring. The windings are dipped epoxy then vacuum pulled to ensure electrical insulation and are secured with Kevlar tie wraps. The insulated windings allow the motors to operate in water. The split-core silicon wire power leads have a max rating (392°F) and come soldered with 24K gold plated bullet connectors for plug and play operation.

KDE Direct offers custom motor designs with vertical integration and a reputation for innovation and on-time delivery. KDE Direct provides solutions to Fortune 500, military and defense, and commercial applications.  


KDE ESCs include customizable features for optimized performance


All KDE Direct Electronic Speed Controllers (ESCs) are dynamically tuned with our motors to achieve smooth and efficient operation with plug and play connectivity. KDE Direct ESCs have an operating temperature up to 221°F, thermal protection at 203°F, and use thermally conductive padding with vibration dampening.

The UVC and HVC series ESCs offer superior thermal management through CNC machined aluminum housing. The UVC and HVC series are rated for dust and water resistance through Ingress Protection (IP) ratings of 66 and 56 respectively.

The UVC series ESCs equips users with live telemetry, back-up throttle control, and data logging capabilities. KDE Direct is committed to research and development of new products, features, and capabilities and offers all ESC software upgrades for free online.


KDE Direct propellers are manufactured with leading edge precision


The KDE Direct Propeller Blade Series provides a professional CNC balanced true-3K carbon fiber for unprecedented flight performance. KDE Direct propellers are dynamically balanced resulting in less vibration and quieter noise compared to conventional propellers. The efficient air foil and light weight rigid design produces higher thrust generation and improved reliability.

The folding propeller blade is designed for high portability and improved flight stability. The centrifugal forces naturally balance the blades as they spin. The folding propellers are also able to produce more thrust than fixed blades as the propeller is able to lead-lag and compensate for the leading edge of the opposite propeller.

KDE Direct propellers are available in dual, triple and hex variants for higher thrust output when the rotor span is limited. Propeller blades come in matching balanced sets with a simple bolt-on installation with KDE Direct adapters and motors.

KDE Direct Propeller Blade Adapters use aerospace grade AL 7075-T6 material, with Class 12.9 alloy hardware for maximum strength and durability. Hex jam-nuts and Belleville spring lock washers provide a mechanical lock and consistent hold to the socket head shoulder cap screws and reduce the need to re-adjust blade pressure and requires minimal maintenance to the assembly between flights.
