Device Manager Software for UAS Electronic Speed Controller (ESC) Series


Note: For the latest Instruction Manual and Software Updates, click the "Specifications" tab above for more technical details and download links.

The new KDE Direct Device Manager Software provides the ability to update all KDE Direct UAS Electronic Speed Controllers (ESC) to the latest production firmware releases, and customize advanced options for multiple applications.  A wide-range of new control-algorithm technologies can be programmed, such as the brushless motor startup power, drive frequency, synchronous rectification, temperature-controlled regenerative-braking, voltage cutoffs, and other market-leading features.

Optimized settings will be automatically applied to the ESC after firmware updates, with no additional changes needed for correct operation with the KDE Direct UAS Multi-Rotor Brushless Motors for most UAS and Multi-Rotor applications.  Advanced programming options are available for alternate systems, such as fixed-wing, single-rotor, and custom flight applications.


System Requirements: Compatible with Windows 2000, XP, Vista, Windows 7, Windows 8.1, and Windows 10. Compatible with Apple® systems, through use of emulation software such as Boot Camp and Parallels® Desktop 13.
