Binding the Transmitter and Vehicle
Refer to the specific instructions in the included manual for the binding procedure. Generally, ensure both the vehicle and transmitter are powered off, then power on the vehicle, followed by the transmitter, and follow the binding sequence.
Tire Selection
The vehicle comes with high-grip knobby tread tires and optional paddle tires. Select the appropriate tires for your driving surface:
- Knobby Tread Tires: Suitable for gravel roads, grass, concrete, and general off-road conditions.
- Paddle Tires: Recommended for sand land or loose terrain to improve traction.

Maintenance
- Cleaning: After each use, especially in dusty or wet conditions, clean the vehicle to remove dirt and debris. Use a soft brush or compressed air. Avoid using water directly on electronic components unless specified as waterproof.
- Lubrication: Periodically check and lubricate moving parts such as universal joints and bearings to ensure smooth operation and prevent wear.
- Inspections: Regularly inspect the vehicle for any loose screws, damaged parts, or worn tires. Replace any damaged components promptly.
- Battery Care: Store Li-Po batteries in a cool, dry place. Do not overcharge or over-discharge. If storing for extended periods, charge them to a storage voltage (typically around 3.8V per cell).
- Chassis: The chassis design incorporates integrated bulkheads. While durable, avoid excessive force that could damage the chassis structure.
