The EPHIL X-40cc-T Pro brings refined twin-cylinder power to your RC aircraft efforts — with a 40 cc (2.44 cu in) displacement, electric starter included, premium spark plugs and electronic ignition all built-in. It’s engineered for high-thrust, low-vibration performance, making it an ideal upgrade for serious sport, scale or aerobatic models. One button start, smooth acceleration, and consistent reliability — mount it, fire it up, and fly with confidence.

Usage

Recommended for large fixed-wing aircraft (approx. 2 m+ wingspan, heavier models) where 4-5HP class power is needed.
The built-in electric starter makes engine activation fast and safe — no manual prop-flipping required
Ideal propeller size range: 20×8, 20×10, 19×8, 19×10 (adjust to aircraft design and altitude)
Ensure your airframe provides strong mounting, appropriate cooling airflow, and vibration isolation given the twin-cylinder design.
Use a gasoline + 2-stroke oil mix (30 : 1) and ensure your ignition supply is within the 6-14 V range for reliable startup.
Before full-throttle operation, complete a proper break-in sequence (varied throttle loads, rich mixture) to maximize longevity.
