Operating Instructions

1. Basic Controls

• Steering Wheel: Turn left or right to control the car's direction.
• Throttle Trigger: Pull to accelerate forward, push to brake or reverse.
• Trim Adjustments: Use the trim dials on the transmitter to fine-tune steering and throttle if the car doesn't drive straight or stops when the trigger is neutral.

2. Driving Tips

• Start Slowly: Begin with gentle throttle inputs to get a feel for the car's responsiveness.
• High-Speed Driving: The K989 can reach speeds up to 30 KM/H. Ensure you have ample space and a clear path before attempting high-speed maneuvers.
• Drifting: The car is equipped with drift tires. To initiate a drift, accelerate, then quickly turn the steering wheel while applying a burst of throttle. Practice is key to mastering drifting.
• Surface: Optimal performance is achieved on smooth, flat surfaces like asphalt or concrete. Avoid rough terrain to prevent damage.

Maintenance

Regular maintenance will extend the lifespan and performance of your RC car.

• Cleaning: After each use, especially if driven in dusty or dirty conditions, clean the car with a soft brush or cloth. Avoid using water or harsh chemicals on electronic components.
• Check for Damage: Inspect the chassis, suspension, wheels, and body shell for any signs of damage or loose parts. Tighten screws as needed.
• Battery Storage: When not in use for extended periods, store the Li-Po battery at a storage charge (around 3.8V per cell) in a cool, dry place. Do not store fully charged or fully discharged.
• Motor Care: Keep the motor free from debris. If the motor overheats frequently, allow it to cool down between runs.
• Tire Inspection: Check tires for wear and tear. Replace worn tires for optimal grip and drifting performance.
