O.S. FS-95V Ringed 4-Stroke Engine for Airplane

The FS-95V has the multi-cylinder look, deeper sound and 4-stroke power that will perfectly complement your next scale project!

  • A bold new head design with individual valve covers and machined aluminum pushrod guides give the FS-95V a classic appearance.
  • Larger displacement than the FS-91, but lighter in weight — yet the FS-95V mounts in the same bolt pattern.
  • Delivers famous O.S. performance, with low amplitude sound that's ideal for scale planes


  • Broad power band for a wide variety of airplanes including models designed for .60 2-stroke and .90 4-stroke engines
  • Redesigned cylinder head to match angled valve layout for steady power at all times and a perfect balance between high combustion and efficient cooling
  • Redesigned "Jet Stream" muffler with unique shape for more authentic four stroke sound
  • Same mounting dimensions, drive hub position and linkage position as the O.S. FS-91 Surpass II, 61FX, 65LA, 75AX, 95AX and FS-110
