Ephil - 38cc Side exhaust - PRO - Gasoline Engine w/ E-Starter - X-38cc-S PRO
Unleash serious power with the EPHIL X-38cc-S Pro — a high-displacement 38 cc gasoline engine featuring an integrated electric starter, electronic ignition, and premium spark plug. Built for demanding RC fixed-wing pilots who want effortless starts and robust performance, this engine elevates your model’s capability. Just install, plug in, press start — and fly.
Usage Notes
- Suitable for larger RC fixed-wing craft where a 38 cc engine provides strong thrust and flight endurance.
- Electric starter + electronic ignition offer considerable convenience, especially for scale models or pilot setups where manual starting is inconvenient.
- Be sure to match the engine with an appropriate propeller size and power system given the 38 cc displacement — larger models will benefit.
- Ensure you provide proper fuel/oil mix, install adequate cooling airflow and ensure the battery/ignition system is compatible with the electric starter.
- As always, review the manufacturer’s break-in, operating and maintenance instructions before use.
