GT-33 Gas Engine
Second in the line of O.S. gasoline engines — but second to none in quality and performance!
When it comes to gasoline aircraft engines, the GT-33 is in a class of its own. It has the muscle to swing larger props, and it stands out for many other reasons, too. The GT-33 runs more quietly than comparable engines while exceeding their output, and it starts easily with electronic ignition that accepts many battery types. Once again O.S. has produced a gas powerhouse for the serious pilot!
- Produces 10% more power than any other engine in its class!
- Electronic ignition system offers fast, easy starting — and accepts LiFe, LiPo, NiCd and NiMH power.
- Rear-mounted Walbro® carb and intake simplify mounting and installation.
- O.S. E-5030 muffler effectively controls exhaust noise without compromising performance.
- Includes Rcexl spark plug.
