A：

1. Put the transmitter and the receiver close to each other (about 50 centimeters) and power both on.

2. Switch on the transmitter and the LED of R7FG will start flashing slowly.

3. There is a black binding button (ID SET) on the side of receiver. Press the button for more than 1 second and release, the LED will flash quickly, meaning binding process is ongoing.

4. When the LED stops flashing and is always on, binding is complete and there will be a signal tower shown on top of the LCD screen of the transmitter. If not succeed, the green LED will keep flashing slowly to notify, repeat the above steps.

Note: If bind to transmitters without screen like T8S or T8FB, the always on LED means binding completed.

A: R7FG is compatible with RadioLink RC8X/ RC6GS V3 V2/RC4GS V3 V2/RC6GS/RC4GS/T8FB/T8S.

A：Make sure the R7FG is also powered on. The BAT pins are specially for model voltage telemetry connection but NOT for power supply to R7FG. Power on R7FG with individual supply within voltage range between 4.6V to 10V.

A：Check the GYRO setting in the menu. Make sure the MIX function is ON and the GYRO sensitivity is well set (100% as advised).

The GYRO Rate value is bigger, the sensitivity is higher while it’s lower if the Rate is smaller. (0% means gyro function is off.)

The GYRO sensitivity can be adjusted by rotating the VR knob (Ch3) of RC6GS/RC6GS V2/RC4GS/RC4GS V2 by factory default.

A: Factory setting is gyro function OFF. Remain R7FG still when power it on as the gyro will self-check. Short press the binding button (ID SET) three times with interval less than 1s, the RED indicator flashes three times. Red LED on/off indicates the gyro function is on/off. The always-on GREEN LED is working mode WITHOUT gyro and the always-on ORANGE(GREEN+RED) LED is working mode WITH gyro.

A：R7FG has four working modes.

Mode 1: PWM+PPM output (factory setting by default)

When the green indicator is on, Ch1 to Ch6 output standard PWM while Ch7 outputs PPM. Short press binding button (ID SET) once to change Mode 1 to Mode 2 and three times within 1 second to Mode 4.

Mode 2: PWM+SBUS output

When the blue indicator is on, Ch1 to Ch6 output standard PWM while Ch7 outputs SBUS. Short press binding button (ID SET) once to change Mode 2 to Mode 1 and three times within 1 second to Mode 3.

Mode 3: PWM+SBUS output + Gyro Function

When both the red and the blue indicators are on (purple), Ch1 to Ch6 output standard PWM while Ch7 outputs SBUS. Meanwhile, gyro function is also on, stabilizing the direction, keeping car from slipping and ensuring safer turning to preventing drifting from fast speed.

Short press binding button (ID SET) once to change Mode 3 to Mode 4 and three times within 1 second to Mode 2.

Mode 4: PWM+PPM output + Gyro Function

When both the red and the green indicators are on (orange), Ch1 to Ch6 output standard PWM while Ch7 outputs PPM. Meanwhile, gyro function is also on, stabilizing the direction, keeping car from slipping and ensuring safer turning to preventing drifting from fast speed.

Short press binding button (ID SET) once to change Mode 4 to Mode 3 and three times within 1 second to Mode 1.

A：If the gyro phase is reversed, short press binding button (ID SET) twice with interval less than 1 second. The red indicator flashes twice mean the gyro phase setting is complete.

A：The slow flashing LED means binding doesn’t succeed or the signal gets lost after binding completes.

A：Yes. It’s strongly advised to change the broken antenna.

A: The operating voltage range of R7FG is from 3V to 12V, supporting high voltage servo.

A：Yes, make sure the battery port to connect with R7FG BAT pins is JST end.

Or it’s advised to use the connect wire packed with R7FG, with one JST end to the BAT pins on R7FG for telemetry function and the other XT60 end to the model voltage as the below picture shows.

A: No, you can't. Because the ESC and receiver are one unit. Only by changing a ESC, then you can change the receiver to RadioLink.

A: Long press bind button, the green indicator will flash. If you press it for a long time, the indicator still stays solid green. The bind button is broken.

A: The antenna of the receiver should be set upright, because car models run on the ground and the boats on the water. Double antennas should be set at a 90-degree angle like below. And do not keep the antenna close to metal parts, electric machine, ESC, or other electronic devices.

A: Make sure to test the battery voltage by multimeter. Because the voltage tested by other voltage test equipment is not accurate. 0.1V difference between the telemetry voltage and the real voltage is normal. If the difference is more than 0.1V, calibrate the voltage of the multimeter and check the difference again.

A: Yes. Any one of CH1-CH6, and PPM/SBUS channel can be used for power on the receiver.

A: R7FG V1.2 is totally the same with V1.3. All functions are exactly the same.

We just changed the contents in the sticker from 4.6V-10V of V1.2 to 3.0V-12V of V1.3. Both R7FG V1.2 and V1.3 support working voltage of 3.0V-12V.

A: The PCB board and pins of R7FG have the same waterproof treatment as the mobile phone, that is, nano-coating technology treatment and the waterproof grade is IPX4.

IPX4: The IP×× rating standard recommended by the International Electrotechnical Commission (IEC). Both the V1.2 and V1.3 versions of R7FG have been designed as Water Splash Proof (IPX4).

A:

1. Check if the ESC plug is reversed.

2. Check if the power supply connects to the telemetry port of the receiver.

Note: The telemetry port of R7FG cannot be used to connect the power supply. It is only for model battery voltage telemetry.

3. Check if the ESC is defective. If the ESC is defective, it cannot supply power to any receiver.

R7FG is burnt out.
