Gasoline power for your .90-1.20 aircraft.

An investment in O.S. gasoline power quickly pays for itself in fast starts, higher power and more flights from your fuel budget.

For the many planes that use 2-stroke .91 or 4-stroke 1.20 glow engines, the GT22 — the third gasoline engine available from O.S. — is the perfect choice. It cranks out nearly 10% more power than other 2-stroke gas engines of similar size!

Throughout the GT22, the fit and finish are outstanding — always delivering the same high performance as when you first installed your brand new, hand-crafted, quality inspected O.S. engine.

  • Uses beam mounting, unlike most other gasoline engines, for easy installation in planes designed for glow power.
  • Pitts style muffler has been reinforced at seams, bends and mounting bolt locations for maximum strength.
  • Redesigned for even easier starting, the IG-02 electronic ignition system handles 4-6 cell NiCd/NiMH or 2-cell LiPo/LiFe batteries.
  • Rear-mounted Walbro carburetor is custom-designed for the GT22 — a choke rod guide has also been integrated into the crankcase for effortless setup.
  • Includes single prop nut with locking nut. Recommended prop sizes: 16x8, 16x10, 17x6, 17x8.
  • Produces nearly 10% more power than other similarly-sized 2-stroke gas engines
  • Electronic ignition system accepts NiCd, NiMH, LiPo or LiFe batteries
  • Uses the same beam mounting as most glow engines, allowing the GT22 to go in many aircraft designed for 1.2 cu. in. glow engines
  • Included Pitts muffler is built to last, with reinforced mounting bolt holes and webbing at high-stress point
Complete package includes engine, muffler, electronic ignition module, CM-6 spark plug, muffler gasket and bolts.
