IMPORTANT: To reduce the risk of fire, bodily injury, and damage to the
equipment, read through Instruction Manual before operating ESC and
always follow all instructions.
KEEP OUT OF THE REACH OF CHILDREN.
Pay attention to the maximum voltage allowed:
KDE-UAS LV Series
KDE-UAS XF Series
KDE-UAS HVC Series
If model is not listed, maximum voltage is stated in specifications.
Operating outside of the listed voltage voids warranty.
All KDE Direct ESCs are opto-isolated and do not provide BEC power output for
the peripheral equipment and requires 3 to 12V applied to the control lead.
Never operate the ESC beyond the specifications stated on hardware. Serious
injury or property damage can result from misuse.
Ensure the polarity is correct with the power supply to the ESC power source
leads. Reverse polarity may cause fire and serious injury and will immediately
damage the ESC beyond warranty coverage.
Ensure the ESC is installed in a safe location and protected to prevent any
exposed connections and solder-locations from contacting conductive areas.
Always use electronics-grade solder and make sure to use proper soldering
techniques and equipment. Poor soldering technique is a common cause of in-
flight failure and ESC damage. Ensure all connectors are protected with
insulation and heat-shrink to prevent unwanted conduction and shorts.
Check all connectors for secure connection before flight. Disconnection due to
vibration and flight-conditions can result in a dangerous loss of control and
potential damage and serious injury.
Do not disassemble or open the ESC or DMA. Opening of the case or removal of
shrink-wrap may cause damage to the internal components, void all warranty
claims, and yield unsafe operation.
Install the ESC in a location with adequate airflow to maintain cool
temperatures and achieve the maximum performance rating.
An electric motor that is connected to the ESC can start unexpectedly and can
cause serious injuries. Always remove the propeller and disengage all gearing
when working on the system with power applied.

Do not allow full submersion of the ESC in water. Water can damage the ESC
and cause malfunction and failure of the electrical components.

Disconnect brushless motor from ESC motor leads before programming ESC.
An electric motor that is connected to the ESC can start unexpectedly and
cause serious injuries or damage.
Before flight, ensure that all ESCs are operating on the same settings and
firmware.
Extending the ESC power leads is at your own risk and voids the warranty.

may result in discontinuity with the motor RPM.
The KDE Direct UAS ESC (Electronic Speed Controller) Series is specifically
designed for multi-rotor applications, and utilizes a proprietary algorithm
for up to 600Hz refresh rate communication and high-speed response for
optimal flight performance.
