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.
- Pitts style muffler has been reinforced at seam, bend and mounting bolt locations for strength.
- Redesigned for even easier starting, the IG-02 electronic ignition system handles 4-6 cell NiCd/NiMH or 2-cell LiPo/LiFe batteries.
- Includes single prop nut with locking nut.
- 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.
The GT22 Pitts muffler is built to last, with reinforced mounting bolt holes and webbing at high-stress points.
Complete package includes engine, muffler, electronic ignition module, CM-6 spark plug, muffler gasket and bolts.
