Description

This high-performance 99cc radial engine is designed with a 9-cylinder configuration, offering a realistic appearance and exceptional performance, making it ideal for scale model aircraft and enthusiast-grade projects. Built for precision and durability, the engine comes ready to run and includes essential components such as an exhaust collector ring, spark plugs, an electronic ignition system, and a solid engine mount.

Installation and operation are streamlined with user-friendly features like integrated choke and throttle bellcranks, allowing for smooth and efficient control. The engine’s construction reflects top-tier engineering standards, with its core components CNC-machined from aluminum or bar stock to ensure accuracy and repeatability. Both the cylinder heads and crankcases are made from aircraft-grade aluminum alloys, delivering strength while minimizing weight.

A heavy-duty double-bearing crankshaft enhances engine longevity and supports reliable high-RPM operation. The pistons are made from billet aluminum and paired with hardened steel rings, contributing to reduced friction and improved compression. The cylinder bores are hard-chromed and lapped to perfection, ensuring optimal wear resistance and performance. Internally, hardened steel cams ensure long-term dependability under demanding conditions.

Designed to run on commonly available 87–110 octane gasoline, the engine uses a 32:1 gas-to-oil mixture, making it suitable for a wide range of applications and climates. Whether for high-end RC models, museum-quality replicas, or functional scale aircraft, this radial engine delivers outstanding realism and reliable operation. Its robust design and attention to detail offer builders and hobbyists a professional-grade powerplant that balances historical authenticity with modern engineering advancements. Ready to bolt in and fire up, this engine provides a powerful and aesthetically accurate solution for those seeking the finest in miniature radial propulsion technology.
