Description

The 5-cylinder radial engine with a 260CC displacement is designed to provide a realistic appearance and exceptional performance, making it an ideal choice for scale model aircraft and precision projects. Its classic 5-cylinder radial configuration offers smooth operation and authentic aesthetics, appealing to hobbyists and professionals alike.

This engine is delivered ready to run, complete with essential components such as an exhaust collector ring, spark plugs, electronic ignition system, and a sturdy engine mount. The inclusion of user-friendly choke and throttle bellcranks ensures easy installation and straightforward operation, allowing users to focus on flying rather than complex setup.

Precision manufacturing is a key feature of this engine. All major components are CNC-machined from aluminum or bar stock, ensuring consistent, repeatable specifications for reliability and performance. The cylinder heads and crankcases are crafted from aircraft-grade alloys, providing an excellent balance of strength and lightweight durability, which is critical for high-performance engines.

Durability and smooth operation are further enhanced by the heavy-duty double-bearing crankshaft, which provides stability and long-lasting performance even at high RPMs. The pistons are made from billet aluminum and paired with hardened steel rings to reduce friction and improve combustion efficiency. The cylinder bores are hard-chromed and carefully lapped to enhance wear resistance and maintain optimal performance over time. Hardened steel cams contribute to precise valve timing and long-term reliability.

Designed to operate on commonly available 87 to 110 octane gasoline, this engine requires a 32:1 gas-to-oil mixture for optimal lubrication and efficiency, making it versatile across various conditions. Overall, the 5-cylinder 260CC radial engine combines traditional radial design with modern engineering excellence, delivering outstanding realism, reliability, and performance for scale model enthusiasts.
