Ushering in a new era in O.S. 4-stroke technology: the 56FS. It's the first in the "" Series, with the latest advancements for boosting your plane's performance.
- Mounts with no-mod ease in the same space as the FS-52.
- In addition to less noise, the muffler features a multi-positional manifold with a rubber O-ring that helps prevent oil leakage.
- A newly designed lubrication system eliminates the need for crankcase ventilation.
- The 40NA carburetor is equipped with a venturi that reduces the chance of fuel leaking out onto the cowl, while also creating more positive air/fuel flow.
It's like giving your 40-size plane a new lease on life!
