In this size plane the glow engines work best. The plane is a little small for a gas engine. It can be done with a BME 44 cc (which would overpower this plane) however the performance would be better with one of the recommended 4 strokes or an OS 1.6 2S or a Moki. If you get another plane in the 82" + range then the gas becomes a really nice option which fly and present better.
