HPI Racing Wheely King 4x4 i12019 Instruction Manual

To assemble the HPI Racing Wheely King 4x4, begin by reading the instruction manual thoroughly. Ensure all parts are present. Start with the chassis assembly, followed by the transmission, suspension, and wheels. Use the provided tools for precise assembly and check each step for accuracy.
Regularly clean the vehicle after each use to remove dirt and debris. Check and tighten all screws and nuts. Lubricate moving parts such as the transmission and differentials. Inspect the tires for wear and replace if necessary. Charge and store the battery properly to extend its life.
First, check the steering servo for proper operation. Ensure the servo horn is tightly secured. Inspect the steering linkage for any damage or misalignment. Verify that the remote control is properly paired with the receiver and that the batteries are charged.
Performance can be enhanced by upgrading to a brushless motor system, installing high-capacity LiPo batteries, and using aluminum suspension parts for better durability. Consider upgrading the tires for improved traction and the shock absorbers for better handling.
Adjust the suspension by changing the shock oil to a thicker viscosity for slower rebound. Adjust the spring tension using preload spacers or choose stiffer springs for more support. Fine-tune the ride height by adjusting the shock mounting positions.
Check the battery charge and connections to ensure proper power delivery. Inspect the motor for overheating and ensure that the ESC is functioning correctly. Verify that all wiring is intact and not damaged. Reset the ESC if necessary.
To waterproof your Wheely King 4x4, use a waterproof receiver box and seal the motor and ESC with a water-resistant coating. Ensure that all electrical connections are secured with waterproof tape or shrink tubing. Consider waterproof servos for complete protection.
Disassemble the transmission housing to access the gears. Remove the damaged gears and replace them with new ones, ensuring correct alignment. Reassemble the transmission, applying a small amount of grease to the gears for smooth operation.
Common causes include worn-out gears, loose drive shafts, and damaged differentials. Inspect these components and replace any that show signs of wear. Ensure all components are properly lubricated and secured. Tighten any loose screws or nuts in the drivetrain.
Use a high-quality charger and follow the manufacturer's charging instructions. Avoid over-discharging the battery by setting a low-voltage cutoff. Store the battery at a 50% charge if it will not be used for an extended period. Regularly check for any signs of damage or swelling.
