4.3 Remote Controller Setup

The T3D remote controller requires 4 AA batteries (not included).

1. Open the battery compartment on the back of the remote controller.
2. Insert 4 AA batteries, observing correct polarity.
3. Close the battery compartment.
4. Familiarize yourself with the controller layout:

Figure 4.2: T3D Remote Controller functions. Key controls include: LED (Light Switch Control), ST.REV (Steering Reverse), TH.TRIM (Throttle Neutral Trim), ST.TRIM (Steering Servo Trim), Power Switch, TH.D/R (Throttle Dual Rate), CH1: ST (Steering), CH2: TH (Throttle), TH.REV (Throttle Reverse).

4.4 Binding the Remote Controller and Car

Your car and remote controller should be pre-bound from the factory. If re-binding is necessary, refer to the specific instructions in the included operating manual.

5. Operating Instructions

5.1 Powering On

1. Turn on the remote controller first.
2. Then, turn on the power switch on the RC car.
3. Wait for the indicator lights on both the controller and car to show a stable connection.

5.2 Basic Controls

• Throttle (CH2: TH): Pull the trigger towards you to accelerate forward. Push the trigger away from you to brake, and push further to engage reverse.
• Steering (CH1: ST): Turn the steering wheel left or right to control the car's direction.
• Trims: Use ST.TRIM and TH.TRIM to fine-tune steering and throttle neutral positions if the car doesn't drive straight or stops when the trigger is at neutral.
• Dual Rate (TH.D/R): Adjust the maximum throttle output. Lowering this can make the car easier to control for beginners.
• LED Lights: Use the LED switch control on the remote to turn the car's lights on or off. The car features a full car linkage lighting system.

5.3 Driving Tips

• Start with low speeds to get a feel for the controls before attempting high-speed maneuvers.
• Practice steering and throttle control in an open area.
• Be mindful of the remote control range (approx. 150m) to avoid losing control.

6. Maintenance

6.1 General Cleaning

• After each use, especially in dusty or dirty conditions, clean the car thoroughly.
• Use a soft brush or compressed air to remove dirt and debris from the chassis, wheels, and suspension components.
• Wipe down the body with a damp cloth. Avoid using harsh chemicals.

6.2 Battery Care and Storage

Figure 6.1: Important battery storage guidelines.

• Always store batteries at approximately half charge (storage voltage) to prolong their lifespan.
• Store batteries in a cool, dry place with minimal temperature fluctuations.
• If not used for an extended period (e.g., 3 months), perform a charge and discharge cycle to maintain battery health.
• Never leave charging batteries unattended.

6.3 Component Inspection

Regularly inspect the following components for wear, damage, or loose connections:

• Drivetrain: Check metal drive shafts, CVDs, and powder metallurgy gears for smooth operation and wear.
• Suspension: Inspect metal hydraulic shocks and metal arms for leaks or damage.
• Bearings: Ensure all full car bearings are clean and spinning freely.
• Electronics: Check all wiring connections to the motor, ESC, servo, and receiver. Ensure the waterproof receiver box is sealed.
• Tires: Inspect tires for wear and ensure they are securely mounted. The car comes equipped with two sets of tires for different terrains.

7. Troubleshooting

• Car not responding: Ensure both the remote controller and car are powered on and batteries are charged. Check for a stable connection (binding).
• Poor steering/throttle response: Check remote controller batteries. Adjust ST.TRIM and TH.TRIM settings. Inspect servo and linkages for damage.
• Reduced speed/power: Battery may be low. Check battery connections. Inspect motor and ESC for overheating or damage.
• Unusual noises: Stop operation immediately. Inspect gears, bearings, and drivetrain for foreign objects or damage.
• Lights not working: Check LED switch on the remote. Inspect wiring to the light system.

8. User Tips

• Break-in Period: For the first few runs, operate the car at moderate speeds to allow the motor and other components to break in properly.
• Battery Management: Invest in multiple batteries to extend your run time. Always allow batteries to cool before recharging.
• Spare Parts: Consider having common spare parts like gears, drive shafts, and suspension components on hand for quick repairs.
• Environmental Awareness: Be mindful of the environment you're driving in. Avoid excessively wet or muddy conditions to protect electronics, even with the waterproof receiver box.

9. Warranty and Support
