Hey, i was wondering what kind of run times you guys are getting with ur ryobis on ggl? i will be running a 16oz tank and spinning a JXF 16-8 prop. i was kinda thinking of sticking this engine in a big 'ol tiger moth or something like that. the reason im wondering about run times is our club has a cross country rally once a year and it takes about an hour to complete it. i think that with a nice slow flying plane, i could do the flight without stopping for fuel
