OS MAX GT 22 with Silencer

The O.S. GT 22 is another engine from the successful GT series which is characterised by low consumption with enormous power. The PD-08 fuel pump ensures a constant supply in all flight conditions and altitudes. The IG-02 ignition ensures quick starting and stable running behavior. The GT 22 is perfect for converting models in the 91 2-stroke or 120 4-stroke class of glow engines to a petrol engine. Unlike many other petrol engines it uses beam mounting for easy installation.

The rear mounted Walbro carburetor is designed for the GT22 with a choke rod guide integrated into the crankcase for easy setup.

Comes complete with IG-02 ignition system and Pitts Style Silencer.

Drops into the same bolt patter as the 65AX glow so makes petrol conversions a breeze!


A superb engine that will give years of trouble free life. It is after all an O.S.!
