How do I properly break in the engine of my HPI Racing D8S 115878 Race Kit?

To properly break in the engine, start by using a high-quality fuel with the recommended nitro content. Run the engine at a rich setting for the first few tanks, allowing it to idle and gradually increasing throttle. Avoid full throttle until the break-in process is complete.

What is the recommended maintenance schedule for the HPI Racing D8S 115878 Race Kit?

Regular maintenance should include cleaning after every run, checking and tightening screws, inspecting the drivetrain and suspension components, and ensuring the air filter is clean and oiled. Perform a thorough inspection and lubrication of moving parts every 5-10 runs.

How can I troubleshoot starting issues with my HPI Racing D8S 115878?

If the engine won't start, check the glow plug for functionality, ensure the fuel is reaching the carburetor, inspect the fuel lines for blockages, and verify that the battery is charged. Also, adjust the carburetor settings to ensure they are not too lean or too rich.

What are the recommended shock oil weights for different track conditions?

For bumpy tracks, use lighter shock oil (around 30-35wt) for better absorption. On smooth tracks, heavier oil (40-45wt) helps maintain stability. Adjust based on personal preference and driving style.

How do I adjust the suspension on my HPI Racing D8S for better handling?

To adjust the suspension, start by tuning the ride height, camber, and toe settings. Use the turnbuckles to adjust camber and toe angles. For ride height, adjust the shock collars to balance the car's weight distribution.
