How do I properly break in the engine of the HPI Racing Pulse 4.6 Buggy?

To break in the engine, begin by using a high-quality nitro fuel with a 20% oil content. Start the engine and let it idle for a full tank without any load. Then, run at half throttle for 2-3 tanks, gradually increasing to full throttle over the next few tanks, ensuring the engine does not overheat.

What is the recommended maintenance schedule for the HPI Racing Pulse 4.6 Buggy?

After every race or extensive use, clean the air filter, check and tighten all screws, and inspect the suspension and drivetrain components for wear. Every 10 runs, perform a more thorough inspection, including the clutch and differentials.
