Difference between...
super cub has different cowl, mainly, as full size had a bigger engine. gas has been good to me- so far- and a lot cheaper to run! a guy at our field just got a new g-26, it runs great. it won't hover his h-9 edge 540, but it flies it all over the place, and hover is about the only thing it won't do. fugi is good, also, but after getting my g-62 powered stinger in the air, the zenoah made a believer outa me! it hovers that 17 pound thing at 1/3 throttle- on a 22-8!! and never misses a beat. also, zenoah has a long history of use. not that fuji is bad, though. saw one of those on a t.f. stinson a mo. ago, and it ran fine, too.
anyway, though, on a cub gas is hard to beat.
