Description

The 5-cylinder radial engine, featuring a 300CC displacement, is designed to deliver both realistic appearance and outstanding performance, making it an excellent choice for scale model aircraft and detailed projects. Its classic 5-cylinder radial configuration ensures authentic aesthetics combined with smooth and reliable operation, meeting the demands of hobbyists and professionals aiming for precision and historical accuracy.

This engine comes fully assembled and ready to run, including essential components such as an exhaust collector ring, spark plugs, an advanced electronic ignition system, and a sturdy engine mount. The user-friendly choke and throttle bell cranks simplify installation and operation, providing ease of use and control for both beginners and experienced builders.

Manufactured with high precision, the engine’s components are CNC-machined from aluminum or bar stock to guarantee consistent quality and repeatable specifications. The cylinder heads and crankcases are crafted from aircraft-grade alloys, which provide a superior balance of strength and lightweight durability, essential for high-performance engines.

A heavy-duty double-bearing crankshaft enhances the engine’s durability and stability, allowing for reliable operation at high RPMs. The pistons, made from billet aluminum and paired with hardened steel rings, contribute to improved combustion efficiency and reduced friction. The hard-chromed and lapped cylinder bores increase wear resistance and maintain optimal performance over extended periods. Hardened steel cams ensure precise and long-lasting valve timing, critical for engine longevity and reliability.

Compatible with commonly available 87 to 110 octane gasoline, the engine requires a 32:1 gas-to-oil mixture for optimal lubrication and efficiency. This combination makes the engine versatile and suitable for various operating conditions. Overall, the 5-cylinder 300CC radial engine offers a professional-grade powerplant solution that expertly balances traditional radial design with modern engineering advancements, delivering exceptional performance and authentic scale realism.
