Onyx ONXM1250 Instructions

Thank you for purchasing the ONYX electronic speed controller
(ESC). Operating RC models can be very dangerous, so please
read this manual carefully.
Please read and understand all warnings before installation
and operation!
OPERATIONAL WARNINGS!
● ALWAYS disconnect the battery from the ESC immediately if
the ESC or battery becomes hot!! Allow the ESC or battery to
cool down before reconnecting.
● NEVER use more than the specifi ed voltage on the ESC's
input.
● ALWAYS mount the ESC in a position where free air can fl ow
through the heat sink during operation.
● ALWAYS turn on the transmitter before connecting the battery
to the ESC.
● ALWAYS disconnect the battery from the ESC when not in use.
● ALWAYS remove the pinion gear when making programming
changes. This will prevent the model from taking off accidentally.
● DO NOT use with brushed motors.
● ALWAYS activate the LVC when using a LiPo Battery. We
recommend a minimum of 3.2V per cell.
● ALWAYS use heat-shrink tubing to insulate any bare wires to
prevent a short circuit.
● ALWAYS allow the ESC to cool before touching. It is normal for
ESCs to get warm during operation.
● ALWAYS unplug the cooling fan if you are using the ESC in wet
conditions.
● DO NOT allow metal/conductive materials to accidentally
make contact across any or all motor/battery posts.
● NEVER power up the ESC before plugging it into the receiver
(Rx) and switching on the transmitter (Tx).
● ALWAYS keep out of reach of children.
● ONYX is not responsible for incidental damage or personal
injury as a result of misuse of this product.
LITHIUM BATTERY CAUTIONS!
This product may use a lithium polymer (LiPo) battery.
Improper handling could result in FIRE! A lithium battery
fi re has the potential to ignite surrounding areas and
may cause property damage or cause personal injury.
● ALWAYS set the LVC to a minimum of 3.2V per cell to prevent
over discharging.
● NEVER leave a LiPo battery unattended while charging or
during operation.
● NEVER operate a vehicle with a LiPo battery inside a building.
● IMPORTANT! Always unplug the LiPo battery immediately
after you've fi nished operating your vehicle.
● ALWAYS charge and store LiPo batteries in a fi reproof location.
Never store LiPo batteries inside the model.
● If you ever see a LiPo battery puff or smoke during operation,
immediately disconnect the battery and move the entire model,
with the battery installed, to a fi reproof location (outside if possible).
● Consult the battery and charger instruction manuals for
additional safety and handling precautions.

C. Connect the "+" and "–" wires of the ESC to the battery pack.
2. THROTTLE CALIBRATION
In order to match the ESC to your transmitter, you must calibrate
it to match the trigger throw. To do this, there are 3 points that
need to be set: neutral, full throttle and full brake.
