Ephil - 76cc Twin - PRO - Gasoline Engine w/ E-Starter - X-76cc-T PRO
Unleash top-tier power with the EPHIL X-76cc T Pro — a 76 cc twin-cylinder gasoline engine designed for serious RC fixed-wing builds. With approximately 9 HP of output and an integrated electric starter plus electronic ignition, this engine combines high performance, precision manufacturing and modern convenience. Whether you’re flying large scale sport, aerobatic or scale models, the X-76cc T Pro delivers smooth starts, refined throttle response and impressive thrust in the 70 cc class. Mount it, hit start, and fly with confidence.
Usage
-
Ideal for large fixed-wing RC aircraft where a twin-cylinder 76 cc engine is justified (e.g., wingspans 2.5 m + / heavier build weights).
-
The built-in electric starter and electronic ignition mean fewer hassles at the field — quick, reliable starts without rope-flipping. (source)
-
Recommended propeller sizes include 22×10, 23×8, 23×10, 24×8 — select according to the model’s weight, wing loading and altitude. (source)
-
Use the correct fuel/oil mixture (typically 30 :1) and ensure ignition supply is within the required voltage range (6-14 V).
-
Make sure your airframe is prepared: proper firewall mounting, sufficient cooling airflow and vibration isolation are key for engines of this size.
-
Before full throttle flight, perform a proper break-in period: moderate throttle usage, rich mixture, gradual load increase to maximize longevity and ensure smooth operation.
-
Because it’s a twin-cylinder opposed engine, expect less vibration compared to single-cylinders—still check all mounting bolts and connections for security.
