Maximum Muscle – Minimum Mess!

O.S. FS110-a Ringed Four Stroke Engines

The FS110-a doesn't compromise on performance, delivering 12.5% more power than the FS-91SII in the same space! Engine blow-by is trapped and re-used to lubricate the working parts inside – meaning there are no more messy cowls or leaks to clean up. What's left is a first-rate engine that sets new standards and exceeds all expectations.

  • Also available in a Pumped version
  • The adjustable F-5040 muffler can be rotated 360° and moved in or out for a perfect fit.
  • Features the same mounting bolt pattern as the FS-91SII 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.
