Additional function / Gyro Link

The Gyro Link is a function that allows you to set the parameters of the car gyro wirelessly from the transmitter.
*A gyro compatible with the wireless setting: GYD550 (As of April 2020)

• The S.BUS servo data can be set wirelessly from the transmitter via the gyro.
• A receiver compatible with the wireless setting function is required. (As of April 2020, R334SBS / R334SBS-E is compatible with wireless setting. Please update the previous receiver to version 4.0 or later.)
• While using Gyro Link wireless (SBUS connection) SBUS servo adjustment will not function.
• To be able to control gyro gain, etc. from the transmitter, it is necessary to enable the gyro mixing funtion of the transmitter.

Using the Gyro Link function
(Preparation)

• Connect the receiver and gyro according to the connection diagram below.
• The connection diagram is a reference diagram for selecting the gyro link connection method. Please read the gyro instructions for details or cautions.

1. Turn on the power switch of the transmitter to display the Gyro Link screen. Turn on the receiver power switch.

BASIC SET

• In the T-FHSS SR mode, the servo position will not adjust until “WRITE”, even if the “LMT” and “NT-OFFSET” functions are adjusted with (+) and (-) buttons .

RESPON (Response mode)
Gyro sensor response setting.

• LOW MID HI speeds up response.
• In high mode, using the dead band angle is too small, the servo will work continuously, but there is no problem in running. However, if strong the servo will work continuously occurs, set to middle or low mode.

LMT A/B (Limit A/B)
Adjustment function of maximum steering angle.

• Operate the steering and adjust the left and right separately so that the maximum steering angle is obtained as long as the tires do not interfere with the arms.
• If the adjustment value of the limit is small (the maximum steering angle is not adjusted), it becomes easier to spin.
• During limit adjustment, the steering angle

SR (SR mode setting)
Set to SR mode.

• Set the SR compatible servo to SR only when using SR mode.

NT-OFFSET (Neutral offset)
Neutral adjustment function of the steering servo.

• Do not use transmitter trim and sub trim. Make the neutral setting with a gyro.

REV (Reverse)
Gyro control direction setting.

• If the car is turned to the left by hand steering goes out on the right.

GAIN MODEGAIN-MODE (Gain mode)(G i d )
Gyro internal control gain switching.

• High gain is 1.5 times more sensitive than standard gain.
• Normally set to standard.
  Set to high gain if increasing the sensitivity setting of the transmitter to the maximum value is not enough.

GYRO DATA
The data can be set independently in each gyro operation mode (AVCS / NORMAL).

Additional / Acuvance Xarvis / XarvisXX compatible (MC (ESC) Link)

The MC (ESC) Link function is now compatible with Acuvance ESC Xarvis and XarvisXX. * Please contact Acuvance for details of Xarvis / XarvisXX functions.

• For Futaba ESC MC960CR, MC950CR, MC851C, MC602C, MC402CR, etc., please choose Other.
• MC970CR is available only in the Japanese market. (As of April 2020)

Additional function / Start

If the track is slippery and you begin to accelerate by pushing the trigger to full throttle, the car wheels will spin and the car 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.

Operation

• When the throttle trigger is moved to the preset position (TRIGGER POINT), the throttle servo moves to the preset position.
• When the throttle trigger is operated slowly so that the wheels will not spin, the car automatically accelerates to the set speed.
• When the throttle trigger is returned slightly, the Start function is automatically deactivated and the set returns to normal throttle trigger operation.

When steering and trigger are operated at the same time.
If you manipulate the trigger to the high side and operate the steering wheel to the right, the tank will turn right at the rate of “FWRD”, “RIGHT”.
If you manipulate the trigger to the high side and operate the steering wheel to the left, the tank turns to the left at the rate of “FWRD”, “LEFT”.
Operating the steering wheel while operating the trigger to the brake side will operate the same as the forward side in the reverse direction.

Additional function / Traction
Trigger operation with cornering on a slippery road surface is hard to get traction and smooth cornering cannot be done. By intermittently pulsing 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.

Operation

• During throttle operation, the throttle servo is intermittently operated in the forward direction.
• You can set the amount of return to the slow side, the amount of delay, the speed of pumping, the operating point, and the duty ratio of pumping.
• You can choose the action on the slow side near the neutral and the action on the high point side.

Switch setting
Use SW1 or SW2 to switch the traction control function ON/OFF.

Dial / Trim Setting
The throttle return amount, delay amount and cycle speed can be controlled with digital trim DT1 to DT5 or digital dial DL1 etc. with the dial select function.

About Fail Safe Unit

• MODE: Function ON/OFF
  Traction control functions ON/OFF setting. When us-ing the Traction control function, set to “ON”.

•   RETN: Throttle return
  Set the ratio at which the servo returns to the slow side with respect to the trigger operation. If set to 0%, the traction control function will not work. At 50%, it re-turns to the neutral position at 50% (half), 100% of the trigger operation amount.

• DELY: Delay

Set the delay from when the throttle is operated until
when the traction control operation starts. When set to Trigger operation 0%, the traction control function works without delay.
At 50%, the traction control function works approxi-

• CYCL: Cycle speed
  Sets the pulse speed (cycle speed). The smaller the set value, the faster the pulse cycle.

• DUTY: Duty ratio

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 ratio can be set to HIGH, MID or LOW.

• TG.P: Trigger point / TYPE: Operating range
  In the throttle operation, set the position of the trigger at which traction control starts to work. Normal / Reverse, reverse the throttle operation range where the traction control operates, with the trigger point as the boundary.
