O.S. GT60 Aircraft Engine

GT60 Gasoline

MORE POWER for 50 cc class aircraft


The GT60 is everything 50 cc fliers want in a gasoline engine — durable, efficient, easy to operate and high performance. A liner-less cylinder makes the engine light, makes it cool faster and gives better exhaust-scavenging characteristics. Plus, its throttle times make the GT60 the choice for 3D flying, delivering power when you need it.
  • Quick-starting IG-02 electric ignition system uses 4-6 cell NiCds/NiMHs or 2-cell LiPos.
  • Rear-mounted Walbro® carburetor is custom-designed for the GT60.
  • Connecting rod features needle roller bearings at both ends.
  • Angled spark plug allows easy installation in tight spaces.
  • Recommended prop sizes: 22x8, 22x10, 23x8, 24x8, 24x10.
