Begin by starting the engine and allowing it to idle for a full tank. For the next 4-5 tanks, drive the car at half throttle, avoiding prolonged full throttle. Gradually increase throttle as you progress through the tanks to ensure proper engine break-in.
Start with the factory settings on the high-speed and low-speed needles. Adjust the high-speed needle first for maximum power while ensuring a slight trail of smoke. Fine-tune the low-speed needle for smooth idle and acceleration.
Check the glow plug and replace it if necessary. Ensure the fuel line is clear and the carburetor is properly tuned. Verify that the air filter is clean and the idle speed is set correctly.
Adjust the shock oil viscosity and spring tension to suit the track conditions. Use softer suspension settings for rough terrain and stiffer settings for smoother, high-speed tracks.
Clean the chassis and engine thoroughly. Check for loose screws and tighten them. Inspect the air filter, clean or replace it as needed, and lubricate all moving parts.
Check the steering servo and linkage for any binding or damage. Ensure that the servo saver is not too loose. Adjust the steering trim on the transmitter for precise control.
Use high-quality nitro fuel with a 20-25% nitro content for best performance. Ensure the fuel is fresh and stored properly to maintain its quality.
Ensure the cooling head is clean and unobstructed. Avoid running the engine too lean, which can increase temperatures. Use a temperature gauge to monitor engine heat and adjust tuning if necessary.
Drain the fuel tank and run the engine until it stalls to clear the fuel lines. Clean the car thoroughly, remove the batteries, and store the car in a cool, dry place. Lubricate metal components to prevent rust.
Use a glow plug wrench to carefully remove the old glow plug from the engine. Insert a new glow plug, ensuring it is seated properly, and tighten it securely without overtightening.
