There are many ways to enjoy the hobby/sport of R/C model airplanes. One of these is to enjoy the experience of flying the replica of a full size aircraft. However, there is more to the flying experience than just the airplane. A replica engine completes the experience. In the past, O.S. Engines developed scale type horizontally opposed and radial engines intended for the scale type airplane.
Now, 70 years after O.S. Engines was founded, O.S. is introducing a new engine for scale modelers - the IL-300 Dia-Star. The IL-300 is a four-cylinder inline engine that reproduces the type of engine widely used in the early 1900s - the dawn of true-to-life aircraft. This engine which embodies the strong spirit of the late Mr. Shigeo Ogawa, the founder of O.S. Engines, has the perfect style and appearance to reproduce the elegance of the full size aircraft in a scale model. From the inline four cylinders to the open push rods and rocker arms, the feeling of realism has been carries out. And even with the engine's scale appearance, every effort has been taken to maintain a high level of performance.
