Used KDEXF-UAS75HVC 75A+HV ELECTRONIC SPEED CONTROLLER (ESC) FOR ELECTRIC MULTI-ROTOR (UAS) in excellent working order with less than 3 hrs flight time.  6 available   Sold as-is

The new UAS HVC series brings to life the next-generation of technology for UAS and Multi-Rotor operation; including an all-Aluminum 6061-T6 case for cool-running temperatures and rugged-construction, allowing the ESCs to be used in a wide-range of harsh environments and commercial/industrial applications (IP56 certification for all-weather operation). The new series also comes pre-loaded with the latest production firmware, including these new, market-leading technologies:

Regenerative Braking – active braking during motor deceleration phase, providing instantaneous response to the flight controller commands and matched-response to acceleration profiles (less “float” during flight).
Temperature-Controlled Synchronous Rectification – new proprietary algorithm for smooth-running motors at low-throttle and improved, faster response under high-peak loads; all while significantly increasing flight-time efficiency and reducing operating temperatures (also termed "active-freewheeling").
Dynamic Timing and Startup Power – optimally-tuned for smooth and precision-controlled startup throughout the full-range of UAS Brushless Motors (no hesitation, stuttering, or response lag).
Increased Drive and Throttle Frequency Resolution – high-accuracy, linear throttle response throughout full-range of operation control.
Motor Synchronization – factory-calibrated ESCs for consistent throttle control and frequency-matched start-up protocols.
The UAS HVC series is compatible with 3S LiPo - 12S LiHV (55V Max) power systems - allowing for the next level of performance and efficiency for your UAS and Multi-Rotor applications. In addition, the UAS HVC series includes active anti-spark circuitry, protecting the integrity and life-span of the critical connectors upon each initial plug-in and system power-up.

The series is tuned and optimized for the KDE Direct UAS Multi-Rotor Brushless Motor Series, for simple plug-and-play operation. No additional throttle calibration is required for most applications and settings are factory programmed.
