A big performance boost for 40-size planes!
Ushering in a new era in O.S. 4-stroke technology: the FS-56-a. It's the first in the alpha 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.
