Safety Precautions

• Always operate your RC vehicle in a safe and open area, away from people, pets, and obstacles.
• Ensure all batteries are fully charged and correctly installed before operation.
• Do not operate the remote control system in wet conditions or near water, unless your RC vehicle is specifically designed for such environments.
• Keep the transmitter and receiver away from extreme temperatures, direct sunlight, and dust.
• Supervise children when they are operating RC vehicles.
• Turn off the receiver first, then the transmitter, when you are finished operating your vehicle.

Setup

1. Transmitter Battery Installation

1. Open the battery compartment cover on the bottom of the transmitter.
2. Insert 4 AA batteries, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

2. Receiver Connection

1. Connect the steering servo to the CH1 port on the receiver.
2. Connect the Electronic Speed Controller (ESC) to the CH2 port on the receiver. The ESC will also provide power to the receiver.
3. If using a third channel device (e.g., lights, gear shift servo), connect it to the CH3 port.
4. Secure the receiver in your RC vehicle, ensuring the antenna is positioned correctly and not obstructed by metal parts.

3. Binding Procedure

The transmitter and receiver are typically pre-bound from the factory. If re-binding is necessary, follow these steps:

1. Ensure the transmitter is turned OFF.
2. Insert the binding plug into the BIND/CH3 port on the receiver.
3. Power on the RC vehicle (which powers the receiver). The receiver's LED should flash rapidly, indicating it's in binding mode.
4. While holding down the BIND button on the transmitter (refer to Figure 4 for location), turn on the transmitter.
5. Release the BIND button on the transmitter once the receiver's LED becomes solid, indicating successful binding.
6. Turn off both the receiver and the transmitter.
7. Remove the binding plug from the receiver.
8. Turn on the transmitter first, then the receiver, to confirm successful binding and operation.

Operating

Basic Controls

• Steering: Rotate the steering wheel clockwise to turn right, counter-clockwise to turn left.
• Throttle: Pull the throttle trigger towards you for forward movement. Push the throttle trigger away from you for reverse/brake.

Trim Adjustments

Use the trim dials to fine-tune the neutral position of your steering and throttle. If your vehicle pulls to one side or moves slightly without throttle input, adjust the corresponding trim dial until the vehicle remains straight and stationary.

Throttle Limit Switch (L-M-H)

This 3-position switch allows you to limit the maximum throttle output. This is useful for beginners, indoor driving, or specific driving conditions where less power is desired.

• L (Low): Reduced maximum throttle.
• M (Medium): Moderate maximum throttle.
• H (High): Full maximum throttle.

Reverse Switches (ST/TH)

These switches reverse the direction of the steering (ST) or throttle (TH) channels. If your steering or throttle responds in the opposite direction to your input, flip the corresponding reverse switch.

CH3 Button

The CH3 button provides an on/off or two-position control for devices connected to the receiver's CH3 port. Its function depends on the connected device (e.g., turning lights on/off, shifting gears).

Maintenance

• Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or harsh chemicals.
• Storage: Store the remote control system in a cool, dry place, away from direct sunlight and moisture.
• Battery Care: Remove batteries from the transmitter if it will not be used for an extended period to prevent leakage.
• Inspection: Periodically check all connections and wires for any signs of wear or damage.
