O.S. Engine OSMG1330 IL-300 Dia-Star Authentic Inline 4-Cylinder Engine  [OSMG1330]

Scale Authenticity and Usable Power in the IL-300 Dia-Star

Scale pilots seeking authentic engine detail will value the O.S. Engine IL-300 Dia-Star for its exposed rocker architecture and narrow inline profile. It reproduces classic looks while providing the performance needed for large-scale kits and restorations.

Traditional Looks Backed by Effective Mechanics

Each cylinder displaces 0.765 cu in, giving the IL-300 Dia-Star the torque and thrust required for heavier airframes. The inline configuration helps maintain correct scale lines and reduces the extent of cowling rework during installation.

Practical Setup for Serious Model Flying

With a single carburetor arrangement, the engine keeps tuning straightforward and maintenance manageable. The operational range of 1,800 to 8,000 RPM fits a variety of flying styles, and 20x10 or 22x8 props are recommended for balanced performance.

The O.S. Engine IL-300 Dia-Star is aimed at experienced hobbyists and restorers who prioritise period-correct presentation without giving up functional flight characteristics. It is a solid option for enhancing large-scale reproductions.
