Usage Notes

Ideal for large fixed-wing RC aircraft where a 38 cc powerplant is warranted.
Bundled with electronic ignition (spark plug included) for consistent startup and dependable operation.
Ensure your airframe supports this size engine: proper firewall, cooling airflow and vibration isolation are key.
Choose a propeller size in the recommended range (e.g., 19×8, 20×10) to match the engine’s output.
Use a clean fuel mix and follow the break-in period as per manufacturer guidelines to maximize engine life.
Pair with ignition power supply (6-14 V) and ensure electrical/ESC setup is compatible.
Regularly inspect mounting and connections — large engines produce significant vibration and thermal load.
