• ON – Solid: The receiver is on and working normally.
• Flashing Quickly: The receiver is in binding mode.
• Flashing Slowly: The transmitter is powered off, or the receiver isn’t receiving a signal from the transmitter.

Interface

• CH1 and CH3 channel interfaces [6] & [7] are standard 2.54mm*3 Pin connectors, which are found on most common servos.
• The battery interface [1] uses a female JST connector. The battery pack must have a male JST connector.
• The motor interface [2] includes a female PH2.0 connector that is built into the receiver/ESC. The included extension uses a male PH2.0 connector on one end and two blade connectors on the other end that connect to the positive and negative terminals found on the motor.

External Antenna

• CAUTION: Do not pull on or bend the receiver’s antenna. Do not fasten the antenna and the servo cable together.
• CAUTION: Keep the receiver’s antenna at least 1cm away from conductive materials such as carbon or metal. If the antenna is too close to conductive materials, it will negatively affect the signal strength of the receiver.

Connections

Receiver/ESC Connections

Receiver/ESC Connections – Side View

Attention!

• Be sure all connections are plugged in correctly. Be sure all connectors are securely plugged in all the way.
• The ESC and the receiver are both housed in a single unit so there is no need to plug in an external ESC.
• There are two 2.54mm 3-pin standard outlets (CH1 & CH3). These outlets are for plugging in a steering servo (CH1) and an optional auxiliary servo (CH3). Do not attempt to plug an ESC into either of these outlets. The
• ESC is already built into the receiver and no external ESC is needed. See the above illustrations for proper connections.

Pay attention to the following when installing the receiver:

1. Make sure the receiver is not installed near a motor or other sources of electrical noise.
2. Keep the receiver’s antenna away from conductive materials such as carbon or metal. To ensure normal function, make sure there is a gap of at least 1cm between the antenna and the conductive material.

Powering ON

Follow the steps below to turn on the transmitter:

1. Check to make sure that the battery is fully charged and installed correctly.
2. Toggle the Power Switch to the ON position, and the R.LED will be solid on.

The transmitter and receiver have already been bound at the factory. However, if the receiver needs to be replaced or additional receivers are bound follow these steps:

1. Turn on the transmitter while pressing and holding the BIND button, and then the transmitter will enter the binding mode. At this time, the G.LED will start flashing quickly. Once in binding mode release the Bind button.
2. The receiver will enter the binding mode automatically when powered on.
3. Once binding is successful, the LED of the receiver will flash slowly, and the transmitter LED will remain solid after being re-powered.
   • Note: When binding, put the transmitter into binding mode first, then the receiver.

Calibration

Use this function to correct for the mechanical deviation of the throttle trigger and steering wheel, for example, deviation occurred in the self- centring or maximum minimum travel, the steps are as follows:

1. Turn and hold the steering wheel clockwise to the max travel and push the throttle trigger forward as far as possible, and at the same time turn on the transmitter, the transmitter will be in calibration mode. The R.LED and G.LED will work in a two-flashing-one-off state repeatedly.
2. Steering Wheel Calibration: Turn the steering wheel to the max and min travel clockwise/counterclockwise respectively. When calibration is completed, the R.LED will be off.
3. Throttle Trigger Calibration: Push/pull the throttle trigger forward/backward as far as it will go. When calibration is completed, the G.LED will be off.
4. Once calibration is complete, press the BIND button to save and exit. The G.LED will be lit solid.

Powering OFF

1. Unplug the battery pack from the receiver and remove it from the vehicle.
2. Turn off the transmitter.
   • Note: Always be sure to disconnect the battery pack from the receiver BEFORE turning off the transmitter.

Channel Reverse

• This function is used to adjust each channel’s direction of movement about its input.
• The ST.REV and TH.REV are the reverse switches for CH1 (steering) and CH2 (throttle).
• If the switch is up, it indicates the channel is in reverse, and if the switch is down, it indicates the channel is in its normal operating mode.
• Example: If the vehicle moves forward while moving the throttle trigger to reverse, flip the TH.REV switch. Refer to PG.3 of this manual for more information.

Steering & Throttle Trims

1. The ST.TRIM+ and ST.TRIM- are the trim buttons for centering CH1 (steering), and can be multiplexed as trims of CH3 and CH4. For multiplexing switching mode, refer to PG.8 “ Mode Switching”.
2. TH.TRIM+ and TH.TRIM- are the trim buttons for centring CH2 (throttle). Adjustment Range: -120us – + 120us, and the step is 4us. Refer to PG.3 of this manual for more information on setting trims.

LED status:

• When pressing the trim keys, the G.LED will flash slowly on short presses and quickly on long presses.
• When the trim adjustment value is at the neutral position, the G.LED will flash twice slowly.
• When the trim adjustment value is at its maximum or minimum setting, the G.LED will not flash at all.
• Note: After the throttle trim is changed, the receiver needs to be re-powered to recognize the new throttle neutral. Otherwise, an exception may occur during vehicle reversing.

Steering Dual Rate

ST.D/R+ and ST.D/R- are used for the CH1 steering servo travel adjustment, which can be multiplexed as CH2 (throttle), CH3, and CH4 servo travel adjustment, refer to “Mode Switching” for multiplex switching mode;

• Adjustment Range: 0-120%(the default is 100%), and the step is 5%.
• ST.D/R+: Increases servo travel.
• ST.D/R-: Decreases servo travel.

LED status:

• When using the D/R keys, the G.LED will flash slowly on short presses and quickly on long presses.
• When the travel adjustment value is at its endpoints (maximum/minimum values of 0/120%), the G.LED will not flash at all.
• Refer to PG.3 of this manual for more information.

Mode Switching

This function is for reusing ST.TRIM(including ST.TRIM+ and ST.TRIM-) and ST.D/R (including ST.D/R+ and ST.D/R-) adjustment buttons for different channels. Refer to [Steering Trims] and [Steering Dual Rates.

• Setup: While the receiver is ON, quickly press the BIND button twice (within 1 second) to cycle through modes 1, 2, 3, and 4. The default setting when powering on is mode 1.
• Mode 1: The G.LED flashes slowly once. The ST.TRIM is used for CH1 trim adjustments and the ST.D/R is used for CH1 end point adjustments.
• Mode 2: The G.LED flashes twice slowly. The ST.TRIM is used for CH1 trim adjustments and the ST.D/R is used for CH2 end point adjustments.
• Mode 3: The G.LED flashes three times slowly. The ST.TRIM is used for CH3 trim adjustments and the ST.D/R is used for CH3 end point adjustments.
• Mode 4: The G.LED flashes slowly four times. The ST.TRIM is used for CH4 trim adjustments and the ST.D/R is used for CH4 end point adjustments.

Calibration

Use this function to correct for the mechanical deviation of the throttle trigger and steering wheel, for example, deviation occurred in the self- centring or maximum minimum travel, the steps are as follows:

1. Turn and hold the steering wheel clockwise to its maximum travel push the throttle trigger forward as far as possible, and at the same time turn on the transmitter. This puts the transmitter into calibration mode. The R.LED and G.LED will both repeat the sequence of “flashing twice-off-flashing twice”.
2. Steering Wheel Calibration: Turn the steering wheel to its maximum left and right position, back and forth. When calibration is completed, the R.LED will be off.
3. Throttle Trigger Calibration: Push/pull the throttle trigger forward/backward as far as it will go. When calibration is completed, the G.LED will be off.
4. Once calibration is complete, press the BIND button to save and exit. The G.LED will be lit solid.

Failsafe

The failsafe function is used to protect the model and surrounding people when the connection fails between the receiver and transmitter. The failsafe is activated when the transmitter is turned off, the transmitter batteries die, or if there is interference. By default, CH2 is the only channel with a failsafe setting. The other channels are not set.

• The failsafe for CH2 is enabled by default and the ESC will enter the braking state when the failsafe is activated.
• For the other channels, the interfaces will maintain the last output when the failsafe is activated.

Setting the failsafe:

1. With the transmitter and ESC both turned ON, hold the control corresponding to the channel at the desired failsafe position.
2. Then press and hold the BIND button for 3 seconds. The G.LED will flash for 2 seconds, indicating that the failsafe setting was saved successfully.

Beginner Mode

• Beginner mode is designed for people who are new to the hobby.
• In this mode, throttle output is limited to 50 per cent and the channel range by default is set to 1250~1500~1750us.

Setup:

• To switch between beginner mode and normal mode, press and hold the CH4 button while turning the steering wheel counterclockwise as far as it will go. While holding, power on the transmitter. The G.LED will flash in a sequence of “flash-flash-off, flash-flash-off”, indicating beginner mode is activated.
• Note: By default, the system is set to normal mode each time it is turned on .

Low Voltage Protection & Overheating Protection

• This receiver has a low-voltage protection function.
• Low Voltage Protection: When the battery voltage is detected to be lower than the safe operating range, power output to all channels will be cut off.
• This receiver/ESC also has an overheat protection function that will cut off power to CH2 when activated. Once the receiver/ESC cools down to normal operating temperature, CH2 will resume to its normal operating power output.

Note: In the event there is a blockage in the drive train, the receiver/ESC will cut off power to the motor (CH2) to prevent damage to both the receiver/ESC unit and the motor. If this happens, inspect the vehicle and clear out anything that may be obstructing the drive-train from spinning freely. This may include lodged sticks, rocks, or anything else binding the drive-train.
