Weight will be your biggest issue. The G38 is not a powerhouse, it is a bit dated and heavy. As far as the Fuji is concerned, no experience of my own but plenty of threads on it. As far as starting goes, make sure you have a spring starter or switch to electronis ignition. For what a G38 cost, for not a lot more you can get the new ZDZ Sportsman 40 w/elctronic ignition, battery, muffler, and prop. Not a bad deal when you add these to a G38. Zenoahs are great reliable engines (have a G62 w/C&H ignition on a Giant Stinger). Just becomes a matter of choice, application and budget. Good luck!
