HPI Racing Savage X 4.6 12867 Race Kit F.A.Q.

How do I properly break in the engine of my Savage X 4.6 12867 Race Kit?

To break in the engine, follow a heat cycle method. Begin by starting the engine and letting it idle for a few minutes to reach operating temperature. Then, run the vehicle at quarter throttle for one tank, half throttle for the next, and gradually increase throttle over 5-6 tanks. Ensure to let the engine cool between runs.

What should I check if my Savage X 4.6 is not starting?

First, check the glow plug to ensure it is functioning. Then, verify that there is fuel reaching the carburetor. Check the batteries in the transmitter and receiver, and ensure the pull-start mechanism is not jammed or broken.

How can I improve the handling of my Savage X 4.6 on rough terrains?

Adjust the suspension settings by changing the shock oil weight to a higher viscosity and use stiffer springs for better absorption. Also, consider adjusting the ride height and camber angles to suit rough terrains.

What maintenance should be done regularly on the Savage X 4.6?

Regular maintenance includes cleaning the air filter after every run, checking for loose screws or nuts, inspecting the fuel lines for leaks, replacing the glow plug if worn, and ensuring the drivetrain components are lubricated and free of debris.

How do I tune the carburetor for optimal performance?

Start with the factory needle settings. Adjust the high-speed needle for top-end performance by turning it clockwise to lean the mixture and counterclockwise to richen it. The low-speed needle controls idle and acceleration; adjust it for smooth throttle response. Fine-tune after each adjustment to avoid engine damage.

What is the recommended fuel for the Savage X 4.6 engine?

Use high-quality nitro fuel with a nitromethane content between 20% and 25%. Ensure the fuel also contains adequate oil content for lubrication.

How can I prevent my Savage X 4.6 from overheating?

Ensure proper airflow to the engine by removing any obstructions. Keep the body shell vented, use a correctly tuned carburetor, and monitor the glow plug and fuel mixture. Regularly check and clean the cooling head and fins.

What should I do if the Savage X 4.6 is losing power during acceleration?

Check the fuel mixture settings on the carburetor, as a lean mixture may cause power loss. Inspect the air filter for clogs, the exhaust for blockages, and ensure the clutch and spur gear are not worn out.

How do I adjust the slipper clutch on the Savage X 4.6?

To adjust the slipper clutch, locate the adjustment nut on the spur gear. Tighten the nut for less slip and more power to the wheels, or loosen it if you need more cushioning for jumps and rough landings. Use small increments to avoid over-tightening or loosening.

What upgrades are recommended for the Savage X 4.6 for better durability?

Consider upgrading to metal spur gears, aluminum suspension arms, and heavy-duty drive shafts. Reinforce the chassis with braces and use high-quality, sealed bearings for improved durability and performance.
