Everyone knows about how the FS-a series has revolutionized the engine industry. Now, the revolution continues with the 72FS-a! Pilots of .60-sized aircraft can now enjoy such benefits as a blow-by internal oil system, which re-circulates excess oil throughout the engine. It all adds up to a first-rate engine that sets new standards while maintaining traditional O.S. quality.

  • 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.
