The most power in its class.


Gasoline power for your .90-1.20 aircraft.


An investment in O.S. gasoline power quickly pays for itself in easy starts, higher power, and more fl ights from your fuel budget. For the many planes that use 2-stroke .90-.91 or 4-stroke 1.20 glow engines, the beam-mounted GT22 is the perfect gas engine choice.


Along with a custom-designed Walbro carburetor — and time-saving, integrated choke rod guide — the GT22 features an electronic ignition system that accepts NiCd, NiMH, LiPo or LiFe batteries. Turn it on, fl ip the prop, and your GT22 is ready to crank out nearly 10% more power than other 2-stroke gas engines of similar size.


Strategic reinforcements give the included Pitts muffl er exceptional strength. Throughout the GT22, the fi t and fi nish are exceptional — always delivering the same high performance as when you fi rst installed your brand new, hand-crafted, quality inspected O.S. engine.
