O.S. leads the way in advanced 4-stroke engine technology, and you’ll see for yourself when you mount the FSa-72II in your model! Sport flyers will enjoy greater performance, while scale pilots will experience more realistic flight. Plus, everyone will benefit from the FSa-72II’s deep, rich sound.

- Features the same mounting bolt pattern as the FL-70 and the FS-70 Ultimate for easy replacement.
- A reversible carb and narrower camshaft housing simplify installation.
