The Tradition Continues...

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.
  • The adjustable F-5030 muffler can be rotated 360° and moved in or out for a perfect fit. Rich, deep sound is an added benefit.
  • 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.
  • Tighter tolerances and updated engineering reduce maintenance and ease set-up.
  • Delivers more performance power to sport pilots and more realistic flight to scale pilots.
