GT22 Gasoline Engine

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 .60-.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 gasoline 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 for easy installation in planes designed for glow power.
  • 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.
