Haven't thought about converting to glow. May be more power but the reason I went to gas was bigger planes and no glow mess to deal with. I am looking at the muffler issue and will be working on that in the future. The way it is now you need a round cowl plane to make it work. Only way I can see to make it work in an Extra or similar would be to put a snorkel style hood scoop on the cowl like a drag car. Might look cool but isn't too practical.
