Put the transmitter and the receiver close to each other within 50 centimeters.2. Turn on the transmitter, then power on the R6FG.3. There is a black button on the R6FG, press the binding button twice in two seconds and release,receiver light start blinking, after about blinking 8 times, match code success then receiver signal LEDalways on!Attention: R6FG default have not turn on the gyro function. Make sure the R6FG keep motionlesswhen power on it, because the R6FG will do the self-test.
RADIOLINK ELETRONIC LIMITEDwww.radiolink.com7R6FG with two indicate LED, green LED on indicate normal working mode while both green and redLED on indicate gyro function working mode.3.2.2 Working ModeR6FG has two working modes：normal working mode and gyro function working mode.Normal Working ModeGreen LED, gyro will not working.Gyro Function Working ModeBoth green and red LED on.Receiver with gyro integrated to hold the vehicle in a straight line during aggressive acceleration andbraking or get bumped around by rough terrain.Receiver with gyro integrated to keep the uni-direction and anti-slip.3.2.3 How to Turn On Gyro FunctionQuick press the ID SET switch two times within 1 second, the LED change from green to red meansgyro function has turn on.Gyro Function SetupIntegrated Gyro, is used to assure the stability of cars on turning status; and keep on straight runningeven the cars get some mechanical phantom. Gyro function can be enabled or disabled.A. Gyro enabledGyro preset disabled, and it enters post indication status. There are two indicators on the receiver. Thegreen one shows the receiver status and the red one is for gyro. When the led turns on, the gyro isenabled , and the led turns off, gyro disabled.B. Gyro enabled forwardCars can be drove forward and backward, gyro is enabled forward or backward correspondingly. Likethe EP cars, different connection will make different direction, the gyro is ensured to be enableforward.C. Gyro reverseSame like a plane has reverse, car kit gyro has reverse as well. Only right set reverse gyro can act tocorrect.Setup(1) Enable gyroPress binding key three time (interval less than 1 second), the red LED will flash three time, indicatingwhether gyro is enabled.(2) Gyro sensitivityGyro sensitivity is predefined to adjust by channel three (factory set VR function), turning the VRswitch clockwise to raise sensitivity and anti-clockwise to decrease.(3) Gyro forward
RADIOLINK ELETRONIC LIMITEDwww.radiolink.com8When the gyro is enabled, pull the throttle trigger and then release (make sure the car stops running),turn the car right or left without changing steering wheel, if the servo will not follow with, it showsgyro is set backward. Press the binding switch one time less than 1 second, the LED flashes red once,gyro is changed to act forward.(4) Gyro reverseSet the gyro forward, turn the car right or left to see whether gyro functions. The wheel will turn leftwhen the car is turned right and the wheel turns right when the car is turned left. If the gyro actscounter, press the binding switch two time, the LED flashes two time red, the gyro reverse iscorrected.Installment of receiver antenna：(1) The antenna must be kept as straight as possible. Otherwise it will reduce the effective range.(2) Large model aircraft may of some metal part interfering signal; in this case the antennasshould be placed at both sides of the model. Then the best RF signal condition is obtained at anyflying attitude.(3) The antennas must be kept away from conductive materials, such as metal and carbon by atleast a half inch. The coaxial part of the antennas does not need to follow these guidelines, but do notbend it in a small radius.(4) Keep the antennas away from the motor, ESC, and other noise sources as much as possible.(5) Press and hold the Easy Link (ID SET) one second, now the receiver starts work.(6) After all of the above steps finished, the LED indicator will turn and keep in red/green.(7) The receiver can be packed by sponge or foam for shocking proof when it is installed to themodel.After all of the above steps finished, turn off the transmitter and then power it on, now the programfunctions to assure it under control of transmitter with a right connection.

Function "A.B.S"Pulse brakeWhen the brakes are applied while cornering with a 4 Wheel Drive or other type of vehicle,under-steer may occur. The generation of under-steer can be eliminated and corners can be smoothlycleared by using this function.Operation- When the brakes are applied, the throttle servo will pulse intermittently. This will have the sameeffect as pumping the brakes in a full size car.- The brake return amount, pulse cycle, and brake duty can be adjusted.- The region over which the ABS is effective can be set ac-cording to the steering operation. (Mixingfunction)Setup itemsABP: Brake return amountDLY: Delay amountCYC: Cycle speedTGP: Operation pointDTY: Cycle duty ratioSTM: Steering mixing-ABP(Amount of brake return): Sets the rate at which the servoreturns versus trigger operation for brake release. When set to 0, the ABS function is notPerformed. When set to 50, the servo returns 50% (1/2)of the trigger operation amount and when setto 100, the servo returns to the neutral position.-DLY(Delay): Sets the delay from brake operation to ABS operation. When set to 0, the ABS function isactivated without any delay. At 50%, the ABS function is activated after a delay of approximately 0.7second and at 100, the ABS function is activated after a delay of approximately 1.4 seconds.-CYC(Pulse speed): Sets the pulse speed (cycle). The smaller the set value, the faster the pulse cycle.- TGP(Trigger point): Sets the trigger point at which the ABS function begins to operate at brake

The data cannot be recovered. Do not reset the model unless you arecertain you want to clear-out that memory and start from scratch.Thank you again for using our product, we hope it can bring you happiness!
