GT55 Racing Gyro V4 For 1/24 1/28 Drift Car

SERVO: Connect to the servo.

Receiver:

• Connect to the receiver's servo channel (CH1).

• Connect to the receiver's control channel (CH3) or leave it unconnected.

Gyro Sensitivity Control:

1. When the gyro sensitivity wire is connected to CH3 on the receiver:

   • The gyro sensitivity is controlled by the CH3 value, which can be adjusted on the transmitter.

   • When the CH3 value is set to 0%, the sensitivity is zero (gyro is inactive).

   • Adjust the CH3 value between -100% and 100% to control sensitivity.

   • Different sensitivity curves are provided for -100% and 100% CH3 values.

   • The gyro offers two optimized sensitivity curves for drift control:

     • -100% to 0%: High sensitivity (Expert mode, fast response).

     • 0% to 100%: Low sensitivity (Beginner mode, slower response, slower servo centering).

2. When the CONTROL channel is not connected:

   • The gyro sensitivity is controlled by the VR (Variable Resistor).

   • When the VR is in the neutral position, sensitivity is zero.

   • Rotating the VR to the left or right increases sensitivity up to 100%.

   • The gyro provides two optimized sensitivity curves for drift control:

     • -100% to 0%: Expert mode, extremely fast response, not suitable for beginners.

     • 0% to +100%: Normal mode, moderate response, recommended for most users.

Recommendation: Adjust the CH3 travel or VR sensitivity between 35% and 60%.

Gyro EPA Adjustment:

1. Forward EPA Setting:

   • First, adjust the EPA (End Point Adjustment) for left and right steering on the transmitter.

   • Press the gyro's "SETUP" button, then turn on the ESC power switch.

   • The gyro LED will flash in the following sequence: one flash → slow flash → fast flash → slow flash. Release the setup button after the slow flash (wait 2 seconds to ensure entering setup mode).

   • Turn the transmitter to the left EPA position (fully left) and hold for a few seconds. The gyro will save the left EPA position, and the servo will return to the center.

   • Turn the transmitter to the right EPA position (fully right) and hold for a few seconds. The gyro will save the right EPA position, and the servo will return to the center. The setup is now complete.

2. Reverse EPA Setting:

   • Press the gyro's "SETUP" button, then turn on the ESC power switch.

   • The gyro LED will flash in the following sequence: one flash → slow flash → fast flash → slow flash. Release the setup button after the slow flash (wait 2 seconds to ensure entering setup mode).

   • Turn the transmitter to the right EPA position (fully right) and hold for a few seconds. The gyro will save the right EPA position, and the servo will return to the center.

   • Turn the transmitter to the left EPA position (fully left) and hold for a few seconds. The gyro will save the left EPA position, and the servo will return to the center. The setup is now complete.

Recommendation: Adjust the CH3 travel sensitivity between 35% and 60%.

Resetting the GT55 Gyro:

If the servo is jittering and the gyro is not functioning properly:

1. Press and hold the gyro's "SETUP" button, then turn on the ESC power switch.

   • The red LED will flash, then flash rapidly, and finally flash slowly until it stays lit (hold the button for about 40 to 60 seconds).

2. Turn off the ESC power and then turn it back on. The gyro will reset and restart.
