GT22

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 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.
