...I'm gainfully self-employed so the cost of neither the engine nor glow fuel is a big concern. Gas engines have many more benefits besides running cheaper fuel.: They run ALOT better, the tank can be placed at CG, and you don't get slop all over your airplane. I already have a DLE 20 in a Four Star 120 that I like. I'm looking at this engine for a smaller airplane that I already have with a glow engine in it that wouldn't be such a pain in the ass to drag to the field.

The only things giving me pause for this engine is that I'm betting that in 2 years there will be 10 engines in this size range, hopefully including one from OS... and that I've read mixed reviews on the engine. it seems like it's not quite 100% sorted out. I read where one guy got a carb that had a defective main needle seat. This, of course, is the kind of thing you don't have to worry about with an OS which makes them worth the extra $$$.
