Description

The 7-cylinder 260CC radial engine is a high-performance powerplant designed to deliver both authentic visual appeal and exceptional functionality for scale model aircraft and advanced RC projects. Its classic 7-cylinder radial configuration offers a realistic, eye-catching design while ensuring smooth, balanced operation—a perfect match for hobbyists and professional builders seeking both performance and scale accuracy.

With a 260CC displacement, this engine provides powerful, reliable output suitable for a wide range of large-scale aviation applications. It comes fully equipped and ready to run, including an exhaust collector ring, spark plugs, an electronic ignition system, and a robust engine mount, significantly reducing setup time. Integrated choke and throttle bellcranks simplify installation and make engine control intuitive and efficient.

Crafted for precision, the engine components are CNC-machined from aluminum or bar stock, ensuring consistent performance and manufacturing accuracy. The cylinder heads and crankcases are built from aircraft-grade aluminum alloys, offering superior strength while keeping weight to a minimum—key for maintaining ideal aircraft balance and handling.

Durability is a core focus of the engine’s internal design. A heavy-duty double-bearing crankshaft enhances stability and supports high-RPM performance. Billet aluminum pistons are paired with hardened steel rings, promoting smoother operation, improved compression, and reduced internal wear. Hard-chromed and lapped cylinder bores further enhance wear resistance and efficiency. Internally, hardened steel cams ensure dependable valve timing, extending the engine’s service life under demanding conditions.

The engine runs efficiently on 87–110 octane gasoline using a 32:1 gas-to-oil mixture, making it adaptable to various environments and fuel types. Whether you’re building a museum-quality replica, a high-end RC aircraft, or a functional scale model, this engine delivers the perfect combination of realism, power, and modern engineering for serious aviation enthusiasts.
