GT22

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.

• Produces nearly 10% more power than other similarly-sized 2-stroke gas engines
