Product details

Install the O.S. FSa-56 Version II engine in your model aircraft and discover the advantages of O.S. 4-stroke technology. Benefits include higher performance for RC sport planes and a more realistic, rich, deep sound that enhances the experience for model builders.

Product Features
The popular FS56-a includes additional upgrades, making the engine even better. It offers more stable operation due to the blow-by oil discharge through the vent nipple on the back plate. The black rocker arm covers give the engine an impressive appearance. The F-4040 muffler can be positioned flexibly, allowing for ideal installation in the model. The engine fits easily and without modifications into any model for which the FS-56a is recommended. Weight without muffler is 377g.
