I was going to suggest a 12 to 16 oz. tank. You really don't want to carry more fuel than you are going to burn during the average flight. It is just extra weight that robs performance.

Gas engines get super fuel economy when compared to glow, as I'm sure you know. Couple that with flying at reduced throttle most of the time, except for ascents and you have an engine that actually burns very little fuel.
