Thank you for purchasing the Onyx
®
sensorless brushless motor. Onyx brushless motors are
high-torque motors designed for bashing and sport racing applications. These 1/10-scale sensor-
less motors feature the same basic dimensions and mounting patterns as industry-standard,
1/10-scale, 540-size brushed motors. These motors also offer high performance over a longer
lifetime with little to no maintenance.
FEATURES
• Perfect upgrade for brushed 540 motors with the same diameter and industry standard
mounting hole patterns
• High torque
• Includes connectors
• High-quality construction with ball bearings and hardened steel 1/8-inch motor shaft

GEARING
Improper gearing will cause excessive heat buildup in the motor and speed control. Use your ve-
hicle’s kit manual in order to find the manufacturer’s recommended pinion size. It is best to monitor
the motor’s operating temperature when you are operating on new and different tracks or racing
surfaces, changing to a new motor or making gearing changes. Your motor’s operating tempera-
ture should never exceed 160° F (71° C). The best place to monitor the motor’s temperature is at
the center of the end bell. If the motor temperature is higher than 160° F (71° C) after a 5 minute
run, the gearing should be lowered (change to a smaller pinion gear).
CAUTION: Once the battery is connected to the motor, stay clear of the rotating shaft
and pinion gear. Failure to do so could result in personal injury.
INSTALLATION OF THE MOTOR
Always ensure the motor mounting screws are long enough to properly seat into the motor. How-
ever, ensure the screws do not enter into the motor too far, which could damage the motor.
The maximum depth that the motor mounting screws can enter into the motor is approximately
1/8 in (3mm). We suggest using the motor mounting hardware included with your vehicle. The use
of screws that are too long will damage the motor and void any warranty.
When installing the motor into your vehicle, it is very important that the gear mesh is correct and
smooth with no binding. The vehicle’s motor mounts usually feature adjustable slotted mounting
holes so that you can adjust the gear mesh properly.
Proper gear mesh (how gear teeth meet) is important to the performance of the vehicle. When
the gear mesh is too loose, the spur gear could be damaged by the pinion gear of the motor. If the
mesh is too tight, speed could be limited and the motor and ESC will overheat. Insert a small piece
of paper in between the pinion and spur gears as you are installing them. Push the gears together
while tightening the screws that mount the motor. When the mesh is at the correct distance,

WATERPROOF COMPONENT
Your new Horizon Hobby Onyx
®
sensorless brushless ESC has been designed and built to allow
you to operate the product in many “wet conditions”, including puddles, creeks, wet grass, snow
and even rain.
While waterproof, this component has not been designed to be immersed in water for long peri-
ods of time and should NOT be treated like a submarine. In addition, most metal parts, including
any screws and nuts, as well as the contacts in the electrical cables, will be susceptible to
corrosion if additional maintenance is not performed after running in wet conditions.
To maximize the long-term performance of your ESC and to keep the warranty intact, it should
only be used as described in the “Usage Conditions” section of this manual. Additionally, the
procedures described in the “Wet Conditions Maintenance” section must be performed regularly
if you choose to run in wet conditions. If you are not willing to perform the additional care and
maintenance required, then you should not operate your vehicle in those conditions.
CAUTION: Failure to exercise caution while using this product and comply with the
following precautions could result in product malfunction and/or void the warranty.

QUICK START GUIDE
The quick start setup guide will get you running quickly using the ESC’s default settings.
1. Mount the ESC and motor in the car.
2. Connect the ESC to the motor.
3. Connect the ESC receiver lead to CH2 on your receiver.
4. Ensure the ESC switch is OFF.
5. Connect a fully charged battery to the ESC.
MOUNTING THE SPEED CONTROL
Mount the ESC in the location specified by your vehicle’s instruction manual. Use double-sided foam
tape to secure the speed control in position.
Ensure all wiring connections can be reached prior to mounting.
Use double-sided foam tape to secure the switch to a convenient location in the vehicle.
CONNECTING THE ESC
1. Connect the ESC terminal A to the motor’s terminal A.
2. Connect the ESC terminal B to the motor’s terminal B.
3. Connect the ESC terminal C to the motor’s terminal C.
If the motor turns in the wrong direction, reverse the connection of any 2 motor wires.
NOTICE: Always disconnect the battery from the ESC when you have finished operating your
vehicle. The ESC’s switch only controls power to the receiver and servos. The ESC will
continue to draw current when connected to the battery, resulting in possible damage to the
battery through over-discharge.
ESC CALIBRATION PROCEDURE
Ensure proper ESC function by calibrating the ESC to your transmitter inputs.
1. Power OFF the ESC.
2. Ensure your transmitter is powered ON, the throttle is not reversed, the throttle trim is neu-
tral and the throttle travel range is at 100%. Disable any special functions such as ABS, etc.
3. Press the SET button while powering ON the ESC. Release the button as soon as the green
LED starts to flash.
4. Calibrate the throttle points by pressing the SET button once after each step.

DESCRIPTIONS
1 Running Mode: Forward Only with Brake: Intended for competition use, this mode allows
only forward and brake controls.
Forward/Reverse with Brake —This mode is the basic all-around mode, allowing forward, reverse
and brake controls. To engage reverse while moving forward, apply the brake until the vehicle has
come to a complete stop, release brake, then apply the brake again. While braking or in reverse,
engaging the throttle will result in the vehicle immediately accelerating forward.
2 Drag Brake Force: Adjusts the amount of brake automatically applied when the throttle is
returned to the neutral position. This simulates the engine braking effect of a full-scale vehicle,
allowing improved turn-in and your vehicle’s general response to controls.
3 Low Voltage Cutoff Threshold: This function helps to prevent battery over-discharge. The ESC
continuously monitors the battery’s voltage. If the voltage falls below the voltage threshold for 2
seconds, the output power shuts off and the red LED flashes twice repeatedly.
The cutoff threshold calculation is based on individual Li-Po cell voltage. For Ni-MH batteries,
if the voltage battery pack is higher than 9.0V, it will be treated as a 3-cell Li-Po battery pack; if
it is lower than 9.0V, it will be treated as a 2-cell Li-Po battery pack. Example: for a 8.0V Ni-MH
battery pack used with a 2.6V/cell threshold, it will be treated as a 2-cell Li-Po battery pack and
the low-voltage cutoff threshold will be 5.2V (2.6x2=5.2). Using the optional Digital Program Box
(DYNS3005), you can adjust the custom values for the cutoff threshold. Unlike the preset values,
custom cutoff values are for the total battery voltage, not individual cell voltage.
4 Start Mode (Punch): Sets the initial throttle punch when the car accelerates. Level 1 gives a
very soft initial acceleration and level 4 gives a stronger initial acceleration.
5 Max Brake Force: Adjusts the maximum braking force. A higher value provides stronger brak-
ing, but can also cause the wheels to lock, resulting in loss of control of the car.
