Ephil Engines 38CC S Engine

Description

This is a single-cylinder side-exhaust engine with a displacement of only 38 cc. The design and mounting method are different from other 30cc engines on the market. The engine body is light and compact, with the perfect size to deliver an excellent flying experience. It uses a Walbro carburetor and NSK bearings to provide better performance and stability.

As a gasoline engine specifically designed for fixed-wing remote-controlled aircraft, the 38cc engine boasts a concise design, excellent performance, and a smooth acceleration curve. It is a favored choice among hobbyists of small and medium-sized model airplanes.

Tech note: The prop bolt pattern on this engine is the same as most 55-70cc engines. Most pre-drilled props in the 19″ – 20″ are drilled for the smaller 30cc-40cc pattern. It is suggested users purchase undrilled props and drill them to the 55cc-70cc pattern.

• • Genuine Fuel Systems: Unlike many competitors that use replica carburetors, Ephil Engines uses authentic Walbro carburetors across their product line to prevent finicky tuning and ensure linear throttle response.
  • Optional Onboard Auto-Starters: Ephil was one of the first brands to make highly integrated electric starters popular. Starters can be bought pre-installed. They use a heavy-duty brushed motor paired with a one-way bearing to safely start the engine from your transmitter switch.
