Ephil - 76cc Twin Gasoline Engine - X-76cc-T
Power meets precision with the EPHIL X-76cc-T — a robust 76 cc twin-cylinder gasoline engine delivering around 9 HP of performance. Equipped with electronic ignition and premium spark plugs, it’s built for serious RC fixed-wing aircraft that demand dependable starts, smooth throttle response, and high thrust. Whether you’re flying sport, scale or aerobatic models, the X-76cc-T brings modern convenience and strong engine dynamics to your build.
Usage
-
Ideal for large fixed-wing RC aircraft (wingspan approx. 2.4 m+ or heavier setups) where a 76 cc displacement is justified.
-
Includes electronic ignition and spark plugs for cleaner, more reliable engine starts — fewer hassles at the field.
-
Recommended propellers include sizes like 22×10, 23×8, 23×10, 24×8 (choose based on model weight and altitude).
-
Use a proper fuel / oil mix (typically 30 :1 gasoline to 2-stroke oil) and ensure the ignition supply voltage is in the 6-14 V range.
-
Ensure your airframe provides strong mounting (firewall, vibration isolation) and sufficient cooling airflow — this engine class generates significant heat and torque.
-
Perform a recommended break-in period before full throttle operation: moderate throttle, rich mixture, varying loads to ensure long-term reliability.
