Click "Receiver List" here to check whether the receiver belongs to FHSS V1 or FHSS V2. If the communication protocol of the receiver is selected incorrectly, binding will fail.
1.3.3 Receiver Connection
1.3.3.1 Connect Cable
Picture 1 Picture 2
The connection wire for the receiver is shown in the picture above. The common ones are white/red/black wire (Picture 1) or yellow/red/brown wire (Picture 2). The two types of servo cables both are light-colored wire as the signal wire, and dark-colored wire as the ground wire, and the middle is 5V power supply, and the three wires correspond to " ".
Note: RadioLink receivers are all designed with anti-polarity connect protection. When the receiver is powered by a separate battery, the receiver will not be damaged if the battery polarity is reversed, but if the servo is connected at this time, it will damage the servo.
Note: Please do the following safety check before operating your model:
RSSI test (Received Signal Strength Indicator). For test method, please refer to the manual Chapter 1.3.7 RSSI Testing.
2. Antenna inspection: The gray line on R8FG is coaxial cable, while the transparent line with a length of about 4-5 centimeters at the top is antenna. If the transparent line is broken or damaged, it will directly affect the control distance. If any abnormality is found, please replace the receiver antenna in time.
1.3.3.2 How to Connect R8FG Correctly for Telemetry
R8FG supports telemetry of model battery voltage, receiver voltage and RSSI. The model voltage will display by connecting the wire to the ESC, battery, and Telemetry port of receiver R8FG. Telemetry of maximum 8S battery(33.6V) supported. Model battery voltage telemetry can be easily achieved by connecting the male end of the battery wire to ESC while the female end to the battery and the wire with a JST head connects Telemetry (+-) of R8FG as below picture shown. No extra module is needed. Once connect with success, the returned model voltage will be displayed on the interface of returned flight information. The connection is as shown below.
Attention:
1. Reverse polarity protection circuit design for all 8 channels of R8FG ensures vital components are protected from a reverse polarity connection. But, the JST connector which packed with R8FG for connect to battery cannot reverse polarity connect, or it will lead to the wrong voltage value telemetry.
2. Telemetry port is only used to model voltage telemetry. It can not be used to power the receiver.
1.3.3.3 Low Model Voltage Alarm Setting

1.3.5 Gyro Function of R8FG
R8FG has a built-in gyroscope. The integrated high-performance gyro adopts the software filter and PID algorithm, timely and precisely corrects the sensitivity and improve the stability. Its good flexibility to different models and fields easily achieves professional performance even with drift cars.
Enable Gyro
Gyro function of R8FG is turned off by default. Since integrated gyro in R8FG will self-check, it is very important to remain R8FG still when powering it on. When red LED is off means NO gyro.
Press binding button three times (interval less than 1 second), the red LED will flash three times, indicating that gyro is enabled.
Attention:
Its normal that the servo keeps shake when connect to receiver, but the transmitter have not operated. Because, the gyro will help to correct the steering gear angle of servo automatically if the gyro function has turned on, you can turn off the gyro function if you do not need this function.
If the receiver has not be moved, but the servo keep shake, there are two reasons as below:
① the servo has connect to the SBUS channel of receiver, please reconnect the servo to other PWM channels, because the standard servo only supports PWM signal input.
② the gyro is too much sensitivity, please reduce the value of gyro sensitivity by turn the DL1 knob switch.
Gyro Reverse
Set the gyro forward, turn the car right or left to see whether gyro functions. The wheel will turn left when the car is turned right and the wheel turns right when the car is turned left. If the gyro acts counter, press the binding button twice, the red LED flashes twice, the gyro reverse is corrected.
Gyro Sensitivity Setup
Gyro sensitivity is default to adjust by channel eight that default controlled by DL1/PS3 knob switch, turning the DL1/PS3 knob switch clockwise to increase sensitivity and anti-clockwise to reduce.
When turning the DL1/PS3 knob switch, tooltip with yellow background color will pop out at the top of the screen, and the value of channel will be changing at the same time, the value is closer to +100, the higher sensitivity. If the value is 0, it means the gyro function have turned off.
If you want set DL1/PS3 to control other function, you can set another switch such as PS1 to as the Gain switch setting in the "Channel setting" menu.
Setting steps: turn on the RC8X into home page, click the button at the left bottom of RC8X into System menu, click
into Mixing menu, click the blue select box named Gyro mixing. Click 1/2 at the top right corner and then Gain switch to assign a switch to control gyro sensitivity.
1.3.6 Installment of Receiver Antenna
It is important to install the receiver antenna correctly on the model, because wrong receiver antenna installation will cause poor signal quality.
How receiver antenna installation affects signal quality? Here are the common mistakes when installing the antennas:
The two antennas of the receiver CANNOT overlap, because they will interfere with each other. Keep the two antennas at a 90-degree angles. (As shown on the right)
Antennas should NOT be placed near metal objects, because reflection of the conductor panel will drastically worsen the signal.
Do NOT keep antennas parallel to the ground. It should be placed vertically to the ground.
Big models may contain metal parts that influence signal emission. In this case. antennas should be positioned at both sides of the model to ensure the best signal status in all circumstances.
Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no over bending.
Keep antennas away from motor, ESC or other possible interference sources.
Sponge or foam material is advised to use to prevent vibration when installing receiver.
Receiver contains some electronic components of high-precision. Be careful to avoid strong vibration and high temperature.
Special vibration-proof material for R/C like foam or rubber cloth is used to pack to protect receiver. Keeping the receiver in a well sealed plastic bag can avoid humidity and dust, which would possibly make the receiver out of control.
Please refer to the below link for more details on how to install antennas of the receiver:
https://www.radiolink.com/newsinfo/886600.html
1.3.7 RSSI Testing
If the control distance of cars or boat is short, please refer to this instruction to test the transmitter. This instruction will introduce the test procedure of the transmitter RSSI value and the solution to the abnormal RSSI value.
Turn on the transmitter and power on the receiver at the same time, and then the transmitter and receiver will be connected (if not connected, you need to bind again), the signal tower appears on the transmitter interface, indicating that the binding is successful. The value of RSSI will appears on the Telemetry tooltip, and the RSSI value will keep changing according to the distance between the transmitter and the receiver. (As shown on the right)
Make the receiver antenna and transmitter antenna parallel, keep transmitter apart from receiver about 60 centimeters and both antennas straight. It is normal that RSSI value is within the range of 0 to -30dBm. The closer the value is to 0, the stronger the signal is. (As shown below)
Here is the tutorial to show how to test RSSI:
https://www.youtube.com/watch?v=RA0NasTZS90
Abnormal signal strength solution:
Check whether the antennas of the receiver and transmitter are damaged. Most signal strength degradation is caused by antenna damage. If it is damaged, the antenna needs to be replaced. If there is no damage, you can test the transmitter and receiver for malfunctions by replacing the receiver. If still cannot solve the problem, email to after_service@radiolink.com.cn to get support.

2.2.10 Fail-safe
This function sets the servo operation position when transmitter signals cannot be received by the receiver for some reason.
The initial value is 0%, which means that when the transmitter signals cannot be received by the receiver, the throttle will stop to output, and the servo will keep its position immediately before the reception was lost.
You can set the value to make the servo move to a preset position you want when the fail-safe function is activated according to your cars or boats. For gasoline engine cars, for safety, we recommend that this fail-safe function be used to set the throttle channel in the direction in which the brakes are applied.
2.2.11 Receiver setting
RC8X is standard packed with R8FG receiver. The binding of them has already finished by default. If you purchase a new compatible receiver, binding needs to be done before using it. The binding steps can refer to 1.3.2 Binding
Receiver select: FHSS V1 receivers have a PWM output resolution of 2048, and FHSS V2 receivers have a PWM output resolution of 4096. The higher the resolution, the more delicate the angle of servo motion.
You can click "Receivers List" to check whether the receiver you are currently using belongs to this list. If yes, please click the box on the right to confirm the current receiver type. If not, please do not select this list.
FHSS V1 Receiver List FHSS V2 Receiver List
If the receiver list selected here does not include the receiver model you are actually using, the binding may not be successful. For example: You are using the RC8X with R7FG receiver, you need to select FHSS V1 to match the code. If FHSS V2 is selected, binding will not be successful.
Servo Speed:
1. Transmitter: It is necessary to update the firmware of RC8X to V1.1.5 or above, and then select FHSS V2 protocol to display this option. Servo speed can be selected from 14ms, 4ms, and 3ms. The factory default servo speed is 14ms (analog servo speed), 4ms and 3ms (digital servo speed).
2. Receiver: If you are using a digital servo, you need to choose a servo speed of 4ms or 3ms. Please confirm whether the receiver you are using supports digital servo. Currently, RadioLink receivers that support digital servo include R8FG V2.1, R4FGM V2.1, and R8FG and R4FGM receivers with a factory date of 2023/4/26 and later. Other versions of RadioLink receivers do not support digital servo. Even if 4ms or 3ms is selected when using them, the default servo speed is 14ms. RadioLink will continue to add other models of receivers that support digital servos in the future. Please pay attention to RadioLink official website.
3. Status indication: When switching the servo speed, the green LED light of the receiver will flash twice, which means that the switching of the servo speed is successful; if the green LED of the receiver does not flash when switching the servo speed of the servo, it means that the switching of the servo speed of the servo is unsuccessful or the current receiver does not support digital servos.
Attention:
RC8X comes with R8FG receiver. R8FG V1.0 (production date before Feb. 6, 2023) only supports FHSS V1 protocol, not FHSS V2 protocol; R8FG V2.0 and later versions (production date on or after Feb. 6, 2023) only support FHSS V2 protocol. Before operating the model, please make sure protocol of the receiver is selected correctly, otherwise some functions will not work properly.
2. The receivers that compatible with the RC8X is keep updating, please pay attention to RadioLink official website www.radiolink.com to get the latest firmware to check the newly launched receiver. This page is only to display the receiver models which are compatible with the RC8X.
2.2.12 Subsidiary ID mode
RC8X can bind with multiple receivers. When RC8X and multiple receivers have been bound successfully, and RC8X and all successfully paired devices are turned on at the same time. There are two ways to use them:
1. When Subsidary ID function is turned off, RC8X can control multiple devices at the same time.
2. When Subsidary ID function is turned on, RC8X can control the specified device according to the selected Subsidary ID. RC8X has 16 groups of Subsidary ID functions, and each ID corresponds to a receiver. Set the Subsidary ID first. When all the devices are turned on, you can control one of the devices through the Subsidary ID function. At this time, the other devices are on standby.
For example: Bind RC8X with a truck and a car and turn all them on. First, use RC8X to control the car to run to the bucket of the truck, and then switch the receiver ID on the truck to drag the car back to the destination.
Subsidary ID mode setting steps:
Tap the button at the right of the "Subsidary ID mode" to change it from "OFF" to "ON". Set the ID number according to your cars or boats and then finish the bind and parameters set for each receiver.

The initial value of Neutral is 0%, -50% to 50% can be selected.
Forward: The servo will jump to the input position at its maximum possible speed. Unlike exponential, which adjusts the whole throttle movement into a curve, throttle acceleration simply "jumps" away from neutral and then leaves the remaining response linear.
Brake1/Brake2/Brake3: same as the Forward. The initial value of Brake1/Brake2/Brake3 is 0%, 0% to 100% can be selected. 0% means no acceleration when brake and 100% means brake side maximum throttle angle. Operation near the throttle trigger neutral position becomes a sharp rise if set the value of Brake1/Brake2/Brake3 to 100%.
Attention: TH in the servo display on the bottom of the screen indicates Throttle. BK1 indicates acceleration of Brake1, BK2 indicates acceleration of Brake2, BK3 indicates acceleration of Brake3.
2.4.5 Steering delay
Quick steering operation will cause momentary understeering, loss of speed, or spinning. steering delay function will very helpful in such cases.
Turn: The default value is "NULL", which means no delay. The delay can be set up to 10 seconds.
Servo operation is delayed
Return: The default value is "NULL", which means no delay. The delay can be set up to 10 seconds.
Servo operation is delayed
Attention:
1. This function limits the maximum speed of the steering servo. (Delay function) The steering delay when the steering wheel is operated (Turn direction) and returned (Return direction) can be independently set.
2. If the steering wheel is turned slower than the set speed, the steering servo is not affected.
3. When the steering delay is turned on, the channel delay function will be disabled.
2.4.6 Throttle delay
Sudden throttle trigger operation on a slippery road will cause the wheels to spin and the vehicle cannot accelerate smoothly. Setting the steering delay function reduces wasteful battery consumption while at the same time permitting a smooth, enjoyable operation.
Attention:
Throttle servo (ESC) operation is delayed so that the drive wheels will not spin even if the throttle trigger is operated more than necessary. This delay function is not performed when the throttle trigger is returned and at brake operation.
Mode:All point, High-Low point, Three-point can be selected.
All point mode High-Low point mode Three-point mode
All point:A delay is set over the entire throttle range.
Turn: The default value is "NULL", which means no delay. The delay can be set up to 10 seconds.

Return:"Low", "Middle", or "High" return direction delay adjustment.
The default value is "NULL", which means no delay. The delay can be set up to 10 seconds.
Servo operation is delayed.
Point1/Point2: Speed switching point adjustment. The initial value of Point1 is 30 and the initial value of Point2 is 60. The default value is "NULL", which means no delay. The delay can be set up to 10 seconds.
Attention:
Setting the speed function in the return direction slows the deceleration of the car body, so please be careful to set it carefully.
When the steering delay is turned on, the channel delay function will be disabled.
2.4.7 Cruise Control
Cruise control can keep the throttle output to a fixed value. When cruise control is enabled, the throttle output will jump to the set value regardless of the current position of the throttle trigger. For example, when using RC8X on a climbing car, you can turn on the cruise control with one switch, and the climbing car can maintain a constant speed without pulling the trigger.
Throttle rate: The fixed output value of the throttle. The setting range is from 0 to +100%.
Tune Buttons: DT1/DT2/DT3/DT4/DL1 can be selected to adjust throttle rate.
Switch: PS1/PS2/PS3/PS4/PS5/Steering/Trigger can be selected to turn on or turn off the cruise control function.
2.4.8 Idle up
The function is used to improve engine starting performance by raising the idling speed when starting the engine of a Gas power car/boat.
Status: to turn on or turn off the Idle up function.
Trim switch: DT1/DT2/DT3/DT4/DL1 can be select to adjust the idle up rate, "NULL": indicate that no switch is set to adjust the idle up rate, but you can also click the value next to the idle up rate in the menu, and then press the [-] or [+] buttons at the bottom of the screen to adjust the rate.
Function switch: PS1/PS2/PS3/PS4/PS5/Steering/Trigger can be selected to turn on or turn off the idle up function, "NULL": indicate that no switch is selected. If the "Status" is set to ON, and the "Function switch" is set to "Null", the transmitter will execute the current idle up rate by default, and it will not automatically turn off.
Idle up rate: The rate can be set from -50% to +50%. You can use the trim switch to quickly adjust the idle up rate, or you can click the value next to the idle up rate, and then press the [+] and [-] buttons at the bottom of the screen to adjust the value.
2.4.9 Throttle Setting (Trigger)
Ratio is the function that set for servo neutral. There are three modes can be selected: Forward 50: Brake 50, Forward 70: Brake 30, Forward 100: Brake 0.
This function allows the selection of the forward side and brake (reverse) side operation ratio by changing the neutral position of the throttle servo.
Forward 50: Brake 50: We regard the entire throttle range as 100%. Set the ratio as Forward 50: Brake 50 means that both forward and brake are account for 50%, and the brake starts at the midpoint of the throttle range.
Forward 70: Brake 30: We regard the entire throttle range as 100%. Set the ratio as Forward 70: Brake 30 means that the forward is account for 70% and the brake is only account 30% of the throttle range. Release the throttle trigger will not brake, you must keep pull the throttle trigger to the brake direction (goes through the new midpoint which reach to 70% of the entire throttle range) to brake.
Forward 100: Brake 0: We regard the entire throttle range as 100%. Set the ratio as Forward 100: Brake 0 means that the forward is account for 100% and the brake are account for 0%, release the throttle trigger and brake immediately. The car cannot go backwards if the Ratio select Forward 100: Brake 0.
Neutral brake
This is a function select switch function. The neutral brake function must specify a switch to turn on or off. The brake rate can be set from 0% to 100%. The neutral brake, which applies the brakes at the neutral position of the throttle trigger, can be set. Confirm that the ESC is in the neutral position and the set is in the operation mode before setting the neutral brake function switch to ON.
Brake rate: the value of neutral brake rate is 0%, 0% to 100% can be set, the rate value must set depends on the ratio mode.
Tune Buttons: DT1/DT2/DT3/DT4/DL1 can be selected to adjust brake rate.
Switch: PS1/PS2/PS3/PS4/PS5/Steering/Trigger can be selected to turn on or turn off the neutral brake function."NULL": indicate that the function is not enabled.
The ESC neutral brake function and Neutral brake function of Throttle setting can be used simultaneously. However, when setting is difficult to understand, we recommend that only one neutral brake function be used.
When the neutral brake function is "ON", the neutral brake rate adjustment is automatically assigned to the throttle trim (DT1, DT2, DT3, DT4, or dial button DL1).
Throttle side EPA function, or ATL function setting also affects neutral brake side operation. The Idle-up 2.3.11 Idle up2.5.9 Engine cut or Engine Cut 2.3.11 Idle up2.5.9 Engine cut function has priority.
2.4.10 Traction control (T.R.C)
Trigger operation with cornering on a slippery road surface is hard to get traction and smooth cornering cannot be done. By intermittently operating the throttle, you can smoothly navigate and travel on topological lines. Also, with a drift car, by intermittently operating the motor in the high point direction, a pseudo reverberator engine sound can be reproduced.
Mixing: The button at the right of "Mixing" is OFF, and the background color of the select box is grey, indicating that the Traction control function is turn off. The button at the right of "Mixing" is ON, and the background color of the select box is blue, indicating that the Traction control function is turn on.
Throttle return: Set the ratio that the servo returns to the slow side of trigger operation. If set to 0%, the traction control function will not work. At 50%, it returns to the neutral position at 50% (half), 100% of the trigger operation amount.
Delay: Set the delay from when the throttle is operated until when the traction control operation starts. When set to 0%, the traction control function works without delay. At 50%, the traction control function works approximately 0.5 seconds later, and the traction control function works about 1 second later at 100%.
Cycle speed: Sets the pulse speed (cycle speed). The initial value is 10, 0 to 30 can be selected. The smaller the set value, the faster the pulse cycle.
Interval rate: Set the ratio of the time to operate to the high side and the time to operate to the slow side in the pumping operation. The initial ratio is 0, can be set to +9 - +0 - -9 in 19 steps.
-9 indicates brake application time becomes shortest which means brakes lock with difficulty.
9 indicates brake application time becomes longest which means brakes lock easily.
Trigger point: When the traction control mixing is turn on, in the throttle operation, set the position that triggers the traction control function to start to work. The initial value is 30, 5 to 95 can be selected.
Trigger mode: Normal or Reverse can be selected.
"Normal" means the high range from the trigger point to the operating range. "Reverse" means the operating range from neutral to trigger point.
The traction control can be select the switch PS1, PS2, PS3, PS4, PS5, Steering switch, and Trigger switch to turn on or turn off, the switch can select in Switch select menu.
2.4.11 A.B.S

Brake channel: A.B.S.1 is default same as the throttle channel, cannot be customized, the channel of A.B.S.2 and A.B.S.3 can be customized, CH1 to CH8 can be selected.
Brake return: Sets the rate that the trigger operation corresponds to the servo returns to position when brake release. When set to 0%, the A.B.S function is not performed. When set to 50%, the servo returns 50% (1/2) of the trigger operation amount and when set to 100%, the servo returns to the neutral position.
Delay: Sets the delay from brake operation to A.B.S operation. When set to 0%, the A.B.S function is activated without any delay. At 50%, the A.B.S function is activated after a delay of approximately 0.7 seconds and at 100%, the A.B.S function is activated after a delay of approximately 1.4 seconds.
Cycle speed: Sets the pulse speed. The smaller the value set, the faster the pulse cycle. The initial value is 10, 0 to 30 can be selected.
Interval rate: Sets the proportion of the time the brakes are applied and the time the brakes are released by pulse operation. The initial value is 0, -9 to 9 can be selected.
ST trigger to start: steering wheel will trigger the A.B.S function when:
① the Steering trigger function is turned on: the button at the right of "Steering trigger" is ON, and the background color of the select box is blue.
② the vehicle is performing a braking operation while operating steering

Tigger mode: Normal and Reverse can be selected. "Normal" indicates the neutral to trigger point is the range of motion. "Reverse" indicates the range from the trigger point to the full brake side is the operating range.
2.4.12 Motor Start
If the track is slippery and you begin to accelerate by pushing the trigger to full throttle, the car wheels will spin and will not accelerate smoothly. When the Start function is activated, merely operating the throttle trigger slowly causes the throttle servo to automatically switch from the set throttle position to a preset point so that the tires do not lose their grip and the car accelerates smoothly.
Attention:
1. When the throttle trigger moves to the trigger point, the throttle servo moves to the preset point position.
2. This function is effective only for the first throttle trigger operation at starting and must be activated before every start.
3. When the throttle trigger is returned slightly, the Start function is automatically deactivated and the set returns to normal throttle trigger operation.
