AFHDS (automatic frequency hopping digital system)
AFHDS was developed for Radio control models and offers active and passive anti-jamming capabilities, low power consumption and high receiver sensitivity. This radio system works in the frequency range of 2.405 to 2.475GHz. This band has been divided into 141 independent channels. Each radio system uses 16 different channels and 142 different types of hopping algorithm. By using various switch-on times, hopping scheme, and channel frequencies, the system is less likely to lose transmission. Each transmitter has a unique ID. When binding with a receiver, the receiver saves that unique ID and can accept only data from that unique transmitter. This avoids picking another transmitter signal and dramatically increases interference immunity and safety.
WARNING: Even with the AFHDS 2A-BS technology, if the radio system is not used in accordance with this manual, it can still fail and cause serious injury. Be sure to read and understand this entire manual, as well as the manual that came with all other RC components you are using.

Receiver Connections

Binding Process
NOTE: The radio is already bound from the factory and only needs to be done if the receiver can’t find the radio’s signal. Before attempting to bind the radio, be sure there are new batteries in the radio, a fully charged battery pack in the vehicle and that both are turned on.

Calibration
This function is used to set the neutral position for the throttle trigger and steering wheel.

Every transmitter is calibrated before leaving the factory, however if recalibration is required, please follow these steps:

1. Turn and hold the wheel as far clockwise as it will turn, move the throttle trigger to the full reverse position and turn on the transmitter. If done correctly, both Red and Green LEDs will double flash on and off.
2. Calibrate wheel: Turn the wheel completely clockwise, then completely counterclockwise. When calibration is completed the Red LED will turn off.
3. Trigger calibration: Pull the trigger to the full throttle position. When calibration is completed the Green LED will turn off.
4. Once calibration is complete press the bind button to save the settings and exit calibration mode.

Radio Functions

CHANNEL DESCRIPTION
The transmitter outputs a total of 4 channels, which are allocated as follows:

• CHl: Steering Wheel
• CH2: Throttle Trigger
• CH3: Accessory Button (2 Position button)
• CH4: Accessory Switch (3 Position Switch)

Note: By default the output of CH3 is in the position of 1000us. Pressing the button will toggle between 1000 and 2000us.

CHANNEL REVERSE
This function is used to adjust each channel’s direction of movement in relation to its input. The STEERING REVERSE and THROTTLE REVERSE switches directly effect CHl and CH2. If the switch is up, the channel is reversed. If the switch is down, the channel is in its normal orientation.

TRIMS
The STEERING TRIM buttons are used to center the steering servo (CHl). If the vehicle steers without transmitter steering input, use these buttons to adjust the vehicle so that it drives straight without steering input from the transmitter. STEERING TRIM can be multiplexed to trim CH3 and CH4. For multiplexing instructions, refer to the [Mode Switching] section.
The THROTTLE TRIM buttons are used to ensure the vehicle remains still while there is no transmitter throttle input (CH2). If the vehicle drives forward or backward without transmitter throttle input, use these buttons to trim the throttle until the vehicle is completely still.

• Adjustment range: -120us- + 120us, each step is 4us.
• STEERING TRIM +/THROTTLE TRIM +: Increases adjustment steps.
• STEERING TRIM-/ THROTTLE TRIM -: Decreases adjustment steps.

LED Indicator:

• While using the trim buttons, the G.LED flashes slowly on short presses and quickly on long presses.
• When the trim adjustment value is in the neutral position, the G.LED will flash twice slowly.
• When the trim adjustment value is at its maximum setting ( + 120us / -120us), the G.LED will no longer flash with each press of the button, indicating it is at its maximum value.

END POINT ADJUSTMENTS (EPA)
STEERING EPA is used to set the steering servo’s maximum amount of travel. This is used to ensure the steering servo provides enough throw to steer the front wheels to their maximum capacity without damaging the servo. To set the steering end points, press the “STEERING EPA (-)” button several times, then turn and hold the transmitter’s steering wheel all the way to one side. Gradually press the “STEERING EPA (+)”button until front wheels have reached their maximum steering capacity. If you hear the steering servo buzzing, press the “STEERING EPA(-)” until the buzzing stops. The end point adjustments can be multiplexed to adjust CH2 (throttle), CH3 and CH4. For multiplexing instructions, refer to the
[Mode Switching] section.

• Adjustment range: 0-120%(the default is 100%), the step value is 5%.
• STEERING EPA +: Increases servo travel.
• STEERING EPA -: Decreases servo travel.

LED Indicator:

• When using the trim keys the G.LED will flash slowly on short presses and quickly on long presses.
• When the end point adjustment value is at its maximum setting, the G.LED will no longer flash with each press of the button.

MODE SWITCHING
This function is for reusing the STEERING TRIM and STEERING EPA buttons for different channels. Refer to the [Trims] and [END POINT ADJUSTMENTS (EPA)] sections above to view their effect on the vehicle.

Function settings:
After turning on the transmitter, quickly press the Bind button twice (within 1 second) to cycle through modes 1, 2, 3, and 4. The default setting when powered on is mode 1.

• Mode 1: G.LED flashes slowly once, STEERING TRIM adjusts CHl and STEERING EPA adjusts CHl.
• Mode 2: G.LED flashes twice slowly, STEERING TRIM adjusts CHl and STEERING EPA adjusts CH2.
• Mode 3: G.LED flashes three times slowly, STEERING TRIM adjusts CH3 and STEERING EPA adjusts CH3.
• Mode 4: G.LED flashes slowly four times, STEERING TRIM adjusts CH4 and STEERING EPA adjusts CH4.

FAILSAFE
This function dictates what the receiver will do in the event that it loses signal from the transmitter, this includes servo position, throttle position, etc

Function settings:

1. Turn on the transmitter and make sure it is connected to the receiver.
2. Hold the control surface at the desired failsafe position.
3. Press and hold the bind button for 3 seconds, the G.LED will flash for 2 seconds, indicating that the settings were saved.

Note: The failsafe function is not set at the factory by default. If no failsafe setting has been set, the receiver will maintain the output of the last signal when the signal is lost. Failsafe is intended as a safety measure during transmitter signal loss and will not work if the receiver loses power.

BEGINNER MODE
Beginner mode is designed for the people who are new to the hobby. In this mode the throttle is limited to 50 percent and the channel range defaults are set to 1250-1500-1750us.

Function settings:
To switch between beginner and normal modes, press and hold the CH3 button while turning the steering wheel completely counterclockwise, as far as it can go. While holding, turn on the transmitter.
Note: By default, the system is set to normal mode. When set to beginner mode, the G.LED will double flash for 3 seconds after turning on the transmitter.

Features

• The integrated design of the ESC and the motor greatly reduces overall volume and weight, making layout and wiring simpler and more convenient.
• High torque and smooth running at very low speeds, which is far superior to common sensored brushless power systems and even rivals brushed power systems at low speeds.
• High efficiency results in low operating temperatures, which extends product longevity. The motor also runs quietly and is very responsive to minor throttle input variations, resulting in maximum control.
• With a protection grade of IP67, the entire system has excellent splash and dust resistance. The whole system can easily handle various weather conditions.
• Intelligent torque output and speed closed-loop control. The system automatically adjusts torque output as the resistance of the motor changes, resulting in smooth steep slope slow descents.
• Five levels of adjustable drag brake force allows the driver to control how the vehicle behaves on steep slopes when they let their finger off the trigger.
• Multiple protection functions: battery low voltage protection, system overheat protection, throttle loss protection, and drivetrain lock-up protection.
• Supports an LED program box to set the ESC parameters, which makes setting parameters more convenient and with less guess work.

Warnings & Compliance

• Please make sure that all wires and connections are well insulated before the ESC is connected to a battery, because a short circuit will damage the ESC.
• Please make all connections carefully. If connected improperly, you may experience abnormal control and/or equipment damaged may occur.
• If you need to re-solder any of the wires or connectors of the ESC, be sure to use a soldering iron rated at least 60W to ensure a firm solder joint and to prevent damage to the ESC.
• Do not let the external temperature of the system exceed 90oC/194oF, high temperatures will damage the power system.
• After use, remember to disconnect the battery from the ESC. If the battery isn’t disconnected, the ESC will continue to drain the battery, even if the ESC is turned off. The battery will eventually be completely discharged if let plugged in for long periods of time, thus resulting in battery failure and possible damage to the ESC. We are not responsible for any damage caused by this!

Connections

• Connect the receiver:
  Insert the ESC/motor’s receiver cable into the throttle channel (CH2) of receiver. The red wire of the ESC/motor’s receiver cable supplies 7.4V to the receiver so there is no need to provide the receiver with an additional power supply. Do not plug an additional power supply into the receiver, as it will damage the receiver. If you want to use an external BEC and power supply, you must first remove the red wire from the ESC/motor’s receiver plug and wrap it with electrical tape or electrical shrink wrap to ensure it doesn’t short out. If the inner metal of the red wire touches anything conductive, the ESC/motor will be damaged.

• Connect the battery:
  Plug in the battery as shown on page 1 of this manual. Be sure to line up the positive with positive and negative with negative polarities.

Powering ON/OFF & LED Status Indicator

• Powering the ESC on and off: Short press the switch button to power on and long press the switch button to power off.
• ESC/Motor tones: Power on the ESC as stated above; the number of beeps emitted by motor indicates the number of LIPO Cells plugged into the ESC. Example: “Beep, Beep” indicates a 2S LIPO; “Beep, Beep, Beep” indicates a 3S LIPO. The last long tone “beep —” indicates that self-check is complete and the ESC can be run.

Note: The power button also flashes in sequence with the motor’s tones.

Setting the ESC Throttle Range & Calibration

1. Turn on the radio, adjust the “D / R”, “EPA”, “ATL” of the throttle channel to 100% (if the radio has no display screen, adjust the corresponding knob to the maximum position), and adjust the “TRIM” of the throttle channel to 0 (if the remote control has no display screen, adjust the corresponding knob to the middle position).
2. In power off state, press the power button and hold it continuously. The red light on the ESC’s switch starts to flash, then release the power button immediately (If the power button is not released within 8 seconds, the ESC will enter other modes, and need to start over) , the motor will sound synchronously.
3. At this time, three points need to be set: the neutral position, the end position of forward and the end position of backward.
   • The throttle trigger stays at the neutral position, press the power button, the green light flashes once, and the motor emits “beep” once, indicating that the neutral position has been stored.
   • Move the throttle trigger to the end position of forward, press power button, the green light flashes twice, and the motor emits “beep” twice, indicating that the end position of forward has been stored.
   • Push the throttle trigger to the end position of backward, press power button, the green light flashes three times, and the motor emits “beep” three times, indicating that the end position of backward has been stored.
4. After calibrating, the motor can be operated normally.

ESC Programmable Items

To set the programmable items, use the LED program box. The instructions can be found on the next page.
NOTE: The black shaded boxes in the following table are the default values of programmable items.

1. Cutoff Voltage: This function is mainly to prevent the irrecoverable damage caused by over discharge of LIPO Cells. If the voltage protection is turned on, the ESC will monitor the battery voltage all the time during operation. Once the voltage is lower than the set threshold value, the power output will gradually reduce to 50% of the normal power within 3 seconds, and the power will completely cut off after about 40 seconds. When entering the low-voltage protection, the red LED will blink in the sequence of  ” . When set to no protection, the ESC will not cut off power due to low voltage and is only intended for NiMH batteries. When using LIPO Cells, you must have the cutoff voltage turned on, otherwise the battery may be damaged due to over discharge. The low, medium and high options correspond to 3.0v/3.2v/3.4v respectively. For NiMH batteries, it is recommended to set this parameter to no protection.

2. Motor Rotation: When the motor shaft is facing the user and the throttle trigger is squeezed, like you would do to drive forward, the shaft turns clockwise when set to CW and counterclockwise when set to CCW. If the vehicle drives in reverse when you are giving it radio input to drive forward, you can change the motor rotation in the ESC. We recommend checking the radio’s throttle reverse function first (see PG. 2).

3. Drag Brake Force: Drag brake represents an automatic braking force on the motor when the throttle trigger moves from a non-neutral position to the neutral position. There are 6 options of drag brake force to adjust, “Disabled” means the drag brake force is 0; the corresponding drag brake force increases from level 1 to level
   5. Select the appropriate drag brake force according to you preference.

4. Drag Brake Rate: This controls how abruptly the drag brake force increases from zero to the set value when the radio trigger enters the neutral range, commonly called slow brake. This value has 5 options to adjust. The higher the level is, the more abruptly the drag brake reaches its full drag brake force value. Level 3 is recommended to can make the vehicle stop with more stability.

5. RPM/Throttle Matching: Permanently Enabled
   When the resistance of the vehicle changes, the ESC will automatically adjust the amount of torque to adequately match the current speed, providing smooth and predictable performance.

6. BEC Voltage: 7.4V at 4A

Setting ESC Parameters
To set the ESC parameters, use the LED program box. Connect the program box as shown below.

Using the LED program box to set ESC parameters.
With the ESC powered off, connect the 3-pin setting interface cable into the ESC’s ON/OFF switch (PRG). Connect the other end of the cable into the program box, using the slot marked ( ). Power on the ESC. After a few seconds, all ESC parameters can be displayed on the program box. Use the “ITEM” button to select the item you wish to change and the “VALUE” button to select the option number of the value you wish to set. (See chart) Press “OK” to save the new parameters to the ESC. Remove the rubber dust plug from the “PRG” port on the ESC switch. Plug one end of the program cable into the switch, being sure the black wire is plugged into the (-) side of the “PRG” port.

Use this port, on the program box to plug in the other end of the program cable. Be sure the black wire is plugged into the (-) side of the port.

Factory Reset
Using the LED program box to restore factory settings. After connecting the program box and the ESC, press the “RESET” button and then press the “OK” button.

Automatic Motor Pairing
If the motor has been subjected to severe impact or has abnormal heating or power output during operation, do the following automatic motor pairing sequence below.

1. Disconnect the ESC from CH2 of the receiver and remove the motor’s pinion gear.
2. Connect the battery, press and hold the ESC’s ON/OFF button. The button will flash red first, then after 8 seconds flash green indicating the ESC is ready to start the automatic motor pairing process.
3. Release the ON/OFF button and the motor will automatically start rotating. Wait for the motor to stop rotating. The red light will flash, indicating that the automatic motor pairing process has been completed.
4. Power off the ESC and disconnect the battery.
5. Reconnect the ESC to CH2 of the receiver and reinstall the motor pinion gear to resume normal operation of the vehicle.

Note: Be sure to remove the motor gear before this operation, otherwise it may lead to incorrect pairing.
