Set Contents The following items are supplied with the GYC470: GYC470 Mini screwdriver Extension cord Sensor tape Nylon strap WARNING Failure to follow these safety precautions may result in severe injury to yourself and others. Check that there is sufficient battery capacity. Do not operate the model and transmitter steering wheel for about 3-5 seconds after turning on the GYC470 (When shared with the receiver). · The GYC470 is activated when the power is turned on. The neutral position is also read at the same time. If initialization is successful, you will see the servo move left and right slightly. Always check the direction of operation of the gyro. Do not strike the gyro with a hard object. Do not drop it onto a concrete surface or other hard floor. · The sensor may become damaged during strong impacts. Do not use trims or mixing. · All corrections are made by the gyro. Therefore, if trimming and mixing are turned on, operation will be the same as driving from the neutral position. Do not use the GYC470 for applications other than RC cars. ·This gyro is designed for RC cars only. Do not use it for other applications. Analog servos cannot be used. ·The use of analog servos may cause servo damage. Do not place gyro near heating equipment (engine, motor, ESC, battery, servo, etc.). · Always allow the gyro to adjust to the outside temeprature before driving. A large temperature change during use will cause drift and other operational issues.

Remote gain is still effective. Mounting to Chassis Use the included double-sided sponge tape to firmly attach the gyro perpendicular to the control axis, at a position where there is as little vibration as possible. Make the wiring loose and bundle it with the included nylon strap so that it will not interfere with the rod. Gyro mounting position The direction of rotation fixed by the gyro can be any direction within 360° relative to the steering axis controlled by the gyro. Included sponge sensor tape Degrease and stick Gyro Horizontal plane Flat surface of the chassis where the sensor tape sticks easily. Mount the gyro level so that it is not tilted relative to the chassis. Steering servo Link the servo according to the kit instruction manual. Adjust the linkage rod so that the trim amount is as small as possible. When using S.BUS servo, initialize a parameter. Make the servo operating range as wide as possible. Equalize EPA (ATV) left and right. SR mode It is possible when using the S.BUS setting compatible transmitter to change the servo to "SR Mode" and improve the servo response. If the servo can't be changed to SR mode, do not set the TX to SR mode. Not compatible with UR mode Adjustments. Setup before a run [ Remote gain use ] Gain adjustments are carried out with a transmitter. Follow this procedure when the gyro's port 2 and the receiver's gain CH are connected (or connected via S.BUS). 1 Run the car in the gyro off mode (gyro gain 0%) and adjust the steering trim (sub trim). 2 Select the appropriate setting for the steering servo that you are using. Servo selection switch of GYC470 should be moved to SR mode ON or OFF. *Do not use a normal digital servo in the SR servo mode (ON). The servo may be damaged. Use a normal digital servo in the SR servo mode (OFF). 3 Turn on your transmitter's power. Set the gyro sensitivity to about 70% at the NORMAL or AVCS side in according to the transmitter's instruction manual. Refer to the <GAIN CH> <AVCS / NORMAL Modes> graph on the next page. Gyro sensitivity zero --- LED OFF AVCS side --- LED red NORMAL side --- LED green *Make the gain tuning adjustment after running the car and noting the behavior. 4 Receiver ON The GYC470 requires 3-5 seconds to initialize when the power is turned on. Do not move the car and do not move the steering wheel during this initialization or the gyro may not initialize properly. Once the initialization process has been completed, the steering servo will move slightly several times, indicating that the GYC470 is now ready for use. If the neutral has shifted, the LED will blink orange. In that case, it reboots. 5 Move the steering wheel left and right and adjust the limit trimmer to maximize servo operation without binding the control linkage or mechanical limits. 6 Using the gyro direction switch, adjust the gyro direction so that steering moves all the way to the right when the car is turned to the left. Correctly set gyro operating direction or the car will not run. If the car is turned to the left by hand steering goes out to the right [ When remote gain function is off ] Adjust the gyro sensitivity with the GYC470 trimmer. If port 2 of gyro is not connected, remote gain is automatically prohibited. (S.BUS connection is excluded) In this case, the limit trimmer is automatically changed to the gyro sensitivity setting trimmer. (Limit adjustment cannot be performed. A limit is fixed to 50 right and left.) 1 Select the appropriate setting for the steering servo that you are using. The GYC470's servo selection switch of GYC470 should be moved to SR mode ON or OFF. *Do not use a normal digital servo in the SR servo mode (ON). The servo may be damaged. Use a normal digital servo in the SR servo mode (OFF). 2 Gain trimmer halfway to the left : NORMAL(green) or right : AVCS (red) from the 70% point. Limit Trimmer Adjustments Steering wheel to full Limit trimmer Adjustments It adjusts to the maximum operation of linkage. AVCS 70% 0% Gyro Sensitivity and mode Switching When the remote gain function is used, NORMAL and AVCS mode switching is performed in accordance with the direction of operation of the transmitter's remote gain channel. At the + rate side, the AVCS mode is selected and at the rate side, the NORMAL mode is selected. The sensitivity is changed by adjusting the end point rate. When the remote gain function is not used, the clockwise direction from the center of the sensitivity setting trimmer is AVCS mode and the counterclockwise direction is NORMAL mode. At the center position, the sensitivity becomes zero and when the trimmer is turned fully to the left or right, the sensitivity becomes 100%. The sensitivity setting criteria by end point is shown in the figure below. 100% GAIN CH Gain 50% AVCS sideLED : RED -110% -55% 0% +55% +110% End point rate 50% NORMAL sideLED : GREEN 100% 3CH (GAIN CH) is set up with reference to the transmitter manual. Neutral position becomes GAIN 0%. It is divided into AVCS side and NORMAL side. Refer to the GYC470's LED. Gyro sensitivity zero --- LED OFF AVCS side --- LED red NORMAL side --- LED green When Port 2 is not used for gain and SBUS/SBUS2 is not used, the trimmer works as the gain adjustment shown below. AVCS 50% AVCS 100% 0% AVCS / NORMAL Modes The gyro has 2 operating modes: NORMAL mode and AVCS mode. In AVCS mode, the angle is controlled simultaneously with NORMAL mode's rate control (swing speed). The AVCS mode increases straight stability more than NORMAL mode. Choose your mode to match your preferences. AVCS Corrects the skidding direction and forcefully maintains the heading. NORMAL Countersteers against outside force, but cannot correct the skid direction. Outside force Outside force D/R (UP side) *Limit is symmetrical from the neutral position. Only proceed with the limit adjustment after completing the trim adjustment. Trimmer operation *Since this gyro is very small, the adjustment trimmer is a small part. Always operate the trimmer with the included mini screwdriver without applying excessive force. NORMAL 70% 3 Receiver ON The GYC470 requires 3-5 seconds to initialize when the power is turned on. Do not move the car and do not move the steering wheel during this initialization or the gyro may not initialize properly. Once the initialization process has been completed, the steering servo will move slightly several times, indicating that the GYC470 is now ready for use. If neutral has shifted, LED will blink orange. In that case, it reboots. 4 Using the gyro direction switch, adjust the gyro's operating direction so that steering moves all the way to the right when the car is turned to the left. Correctly set the operating direction or the car will not run. NORM 50% NORM 100% Tuning Adjustment Drive the vehicle and adjust the gyro sensitivity. 1 Always re-trim with the gyro gain at 0. 2 In this state, turn the receiver power OFF ON. The neutral position is memorized. Steering trim must not be performed while the car is running. S.BUS System Unlike conventional radio control systems, the S.BUS system sends operating signals from the receiver to a gyro or other S.BUS compatible devices by data communication. The S.BUS compatible device executes only executes data for the channels it sets. For this reason, multiple servos can be connected to the same signal line. The S.BUS system requires a dedicated S.BUS receiver and S.BUS servo (gyro, etc.).
