I think there is one close to that small. RCS SV 17 (17cc) is about equivalent to a 0.91 c.i. glow engine.

I prefer gas to glow-fuel. There is still an oil to be mixed (they are both two-stroke) but the gasoline & Husquvarna oil is still 1/4 the cost of glow-fuel ("Nitro", though some contains no nitromethane). The Walbro carbs used in gassers are much more complicated than any glow carb and can be cranky (especially with ethanol creaping into our gasoline). But you spotted the big difference. Gas engines are large and heavy and require lots of model to lift them.

You can convert small glow engines to diesel. That may be an option.

I still fly glow engines most often. Mostly because the slammer .40 and .60 size models are easier to transport and faster to rig (my gassers are 1/5th and 1/4 scale biplanes).
