4.1 Working mode setting
Turn on/off the gyro: Short press the binding button 3 times within 2 seconds to switch the gyro on and
off, and the color of the LED indicator will switch accordingly
Gyro phase switch: Short press the binding button twice within 2 seconds to switch the gyro phase.
Turning on/off the SBUS: short press the binding button once to turn on/off the SBUS, and the color of
the LED indicator will switch accordingly. After SBUS signal is enabled, channel 1-6 output PWM;
channel 7 outputs the PPM signal, and channel 8 outputs the SBUS signal.
4.2 LED Indicator Color in Different Working Modes
Note: When the receiver is connected to the power supply, if there is no successful binding between the
receiver and the transmitter or the receiver loses the signal, the indicator of the receiver will flash slowly.
5. Gyro Introduction
5.1 Gyro Function
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 improves the stability. Its good flexibility to
different models easily achieves professional performance even with drift cars.
5.2 Gyro Enable
The gyro function of R8FG is turned off by default. Since the integrated gyro in R8FG will self-check, it is
important to keep R8FG still when powering it on. Red LED is the gyro status indicator . When the red
LED off means NO gyro. Press the binding button three times (intervals of less than 1 second), the red
LED will flash three times, indicating that gyro is enabled.
Attention: It's normal that the servo keeps shaking when connected to the receiver. Because the gyro is
helping to correct the steering gear angle of the 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 to be moved, but the servo keep shaking, there are two reasons below:
①The servo has connected to the PPM/S.BUS channel of the receiver. Please reconnect the servo to
the CH1/2/3/4/5/6, because the standard servo only supports PWM signal input.
②The gyro is too much sensitive. Please turn DL1 switch to reduce the gyro sensitivity.
5.3 Gyro Reverse
Set the gyro forward, and turn the car right or left to see whether the 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.
