1. Introduction
This manual provides detailed instructions for the setup, operation, and maintenance of your GoolRC TG3 2.4G 3CH RC Transmitter and Receiver. This system is specifically designed for remote control cars and boats, offering reliable performance with its 2.4GHz remote system.
The TG3 system features intelligent design, supporting multi-device and multi-user operation simultaneously. It boasts fast response speed, strong anti-interference ability, very low power consumption, and high receiving sensitivity. A special speed limit function is included, allowing beginners to control RC vehicles within a limited speed range, enhancing safety and ease of use.
2. Package Contents
Please check the package carefully to ensure all items are present:
- 1 x GoolRC TG3 Transmitter
- 1 x TG-3 Receiver
- 1 x Paster (Adhesive pad)
- 1 x Match Line (Binding cable)
- 1 x English Manual (This document)
3. Setup
3.1 Transmitter Battery Installation
- Locate the battery compartment on the bottom of the transmitter handle.
- Slide open the battery compartment cover.
- Insert four (4) 1.5V AA batteries (not included) into the compartment, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
3.2 Receiver Connection and Binding
The receiver (Model TG-3) needs to be connected to your RC car or boat's electronic speed controller (ESC) and steering servo, and then bound to the transmitter.
- Connect the Receiver: Connect the ESC to Channel 2 (TH) and the steering servo to Channel 1 (ST) on the receiver. If your model has additional functions, connect them to Channel 3 (CH3) as needed. Ensure the power supply to the receiver is within 4.0 - 6.5V DC.
- Binding Process:
- Ensure both the transmitter and receiver are powered off.
- Connect the 'Match Line' (binding cable) to the BIND port on the receiver.
- Power on the receiver. The LED on the receiver should start flashing, indicating it's in binding mode.
- Press and hold the 'BIND' button on the transmitter (refer to Figure 3 for location).
- While holding the BIND button, power on the transmitter.
- Release the BIND button on the transmitter once the LED on the receiver turns solid, indicating a successful bind.
- Power off both the transmitter and receiver.
- Remove the 'Match Line' from the receiver.
- Power on the transmitter first, then the receiver. The system should now be linked and ready for operation.
4. Operating Instructions
Familiarize yourself with the transmitter's controls before operating your RC vehicle.
4.1 Basic Controls
- Power On/Off: Use the switch located on the top left of the transmitter to power the unit on or off.
- Steering Wheel: Turn the wheel left or right to control the steering of your RC vehicle.
- Throttle Trigger: Pull the trigger towards you to go forward, push it away to go backward (brake/reverse).
4.2 Trim and Rate Adjustments
- Steering Trim Dial (ST.TRIM): Adjusts the neutral position of the steering. If your vehicle pulls to one side when the steering wheel is centered, use this dial to correct it.
- Throttle Trim Dial (TH.TRIM): Adjusts the neutral position of the throttle. If your vehicle creeps forward or backward when the throttle trigger is centered, use this dial to correct it.
- Turn Steering Rate (D/R): Adjusts the maximum steering angle. This can be used to limit how sharply the vehicle turns.
4.3 Reverse Switches
- Reverse Switch Throttle (TH.REV): Reverses the direction of the throttle channel. Useful if your vehicle goes backward when you pull the trigger forward.
- Reverse Switch Steering (ST.REV): Reverses the direction of the steering channel. Useful if your vehicle turns left when you turn the wheel right.
4.4 Third Channel (CH3)
The third channel (CH3) is typically used to control auxiliary functions on your RC vehicle, such as lights, winches, or sound systems. The specific button or switch for CH3 control is labeled on the transmitter (refer to Figure 3).
4.5 Throttle Limit Switch (TH.LIMIT)
The throttle limit switch allows you to set a maximum throttle output, which is particularly useful for beginners or when operating in confined spaces. This helps prevent accidental high-speed maneuvers.
4.6 Low Voltage Warning
The transmitter is equipped with a low voltage warning system. If the battery voltage drops below 4V, an indicator (usually an LED or audible alert) will activate, signaling that the batteries need to be replaced soon.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using harsh chemicals or solvents.
- Storage: Store the unit in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries from the transmitter if it will not be used for an extended period to prevent leakage.
- Avoid Moisture: Keep the transmitter and receiver away from water and high humidity to prevent damage to electronic components.
- Handle with Care: Avoid dropping or subjecting the unit to strong impacts, as this can damage internal components.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Transmitter not powering on | Dead or incorrectly installed batteries. | Replace AA batteries, ensuring correct polarity. |
| Vehicle not responding to controls | Not bound correctly; receiver not powered; receiver/transmitter too far apart; low battery in transmitter or vehicle. | Perform binding process again. Check receiver power. Ensure close proximity. Replace transmitter batteries or charge vehicle battery. |
| Vehicle steering/throttle reversed | Steering/Throttle reverse switch incorrectly set. | Adjust the ST.REV or TH.REV switch on the transmitter. |
| Vehicle drifts or moves slightly when controls are centered | Steering/Throttle trim incorrectly set. | Adjust the ST.TRIM or TH.TRIM dial until the vehicle remains still or tracks straight. |
| Limited turning radius | Steering Dual Rate (D/R) set too low. | Increase the Turn Steering Rate (D/R) dial. |
| Vehicle speed is limited | Throttle Limit Switch engaged. | Disengage or adjust the Throttle Limit Switch. |
