HPI Racing Savage XL 12039 Race Kit F.A.Q.

How do I properly break in the engine of my HPI Savage XL 12039 Race Kit?

To break in the engine, start by running the engine at idle for two tanks of fuel, gradually increasing throttle. Avoid full throttle until after the break-in period has completed. This process helps ensure the longevity and performance of your engine.

What is the recommended fuel for the Savage XL 12039 Race Kit?

For optimal performance, use a high-quality 20-25% nitro fuel specifically designed for RC cars. This provides the necessary lubrication and performance for the engine.

How can I tune the carburetor for better performance?

Begin by adjusting the high-speed needle for maximum RPM at full throttle, then adjust the low-speed needle for smooth acceleration. Ensure the idle is set to prevent the car from moving when the throttle is released.

What should I do if the engine won't start?

Check for fuel flow, ensure the glow plug is operational, and verify the carburetor settings. Also, inspect the air filter for blockages and ensure the fuel is fresh.

How often should the air filter be cleaned?

Clean the air filter after every 3-5 runs to ensure optimal engine performance and prevent dust and debris from entering the engine. Use a mild soap and water solution, allow it to dry, and lightly oil before reinstallation.

What maintenance is required for the drivetrain?

Regularly inspect and clean the gears, apply a suitable lubricant, and check for any wear or damage. Ensure the differentials are filled with the appropriate weight oil for smooth operation.

How can I improve the suspension setup for racing?

Adjust the shock oil viscosity, spring tension, and preload to suit track conditions. Softer setups provide better traction on rough terrain, while stiffer setups improve stability on smooth surfaces.

What should I check if the radio control has poor range?

Inspect the antenna for damage, ensure the batteries in both the transmitter and receiver are fully charged, and check for any potential sources of interference. Rebinding the transmitter and receiver may also help.

How do I replace the glow plug on my engine?

Use a glow plug wrench to remove the old glow plug, then carefully install a new one by hand-tightening it. Ensure not to overtighten, as this can damage the threads.

Why is my Savage XL engine overheating?

Check the fuel mixture to ensure it's not too lean, verify the cooling head is free of obstructions, and ensure the air filter is clean. Running the engine too hard without proper cooling can also cause overheating.
