Maintenance

The GoolRC WLtoys 12428 is built with a super strong structure, including a durable frame, cockpit, shock absorbers, and motors, designed to withstand rigorous use.

• Durability: The car's robust design and reinforced rubber wheels contribute to its high durability, minimizing damage from impacts and flips.

• Cleaning: After off-road use, it is recommended to clean the car to remove dirt, dust, and debris from the chassis, wheels, and suspension components to maintain optimal performance.

Troubleshooting

• Abrupt Stop: The car is designed to stop abruptly when the battery charge is low, rather than gradually slowing down. This indicates it's time to recharge the battery.
• Flipping/Rolling: Due to its high speed, the car may flip or roll during sharp turns, especially at maximum speed. This is normal behavior for high-performance RC vehicles. The car's durable construction is designed to withstand such impacts.
• Loss of Control: Ensure the remote control batteries are fresh and the car's battery is adequately charged. Check the trim adjustments on the remote to ensure proper steering alignment.
