Manufacturer: Saito Engines


  • 10 X 4 prop at 10,500 rpm
  • Smaller case design for lighter weight
  • Nearly the same case size as a .30, but packs more power

As far as modelers are concerned, there’s no sound like the sweet sound of a SaitoTM engine. Saito’s latest wonder is the FA-40a, which shares nearly the same case size as the FA-30, but packs a whole lot more punch. All this power coupled with solid Saito craftsmanship and the standard 3-year warranty is sure to make this potent little 4-stroke one of the year’s most anticipated engines. As with most Saito engines, a special Golden Knight edition is available with a gloss black case and gold plated rocker covers.
