fuel consumption

how fast does .12 or .15 consumes fuel? compared to a .21?

At about half. When we race my .21 mono (technically my boat, but my son races it), we use about 6-8 oz. of fuel depending on conditions. On my .12 boats, I'm using 4 oz. tanks and have enough to complete a race according to what I've figured. My .45 will use generally 8-10 oz. if that gives you any indication. This includes warm-up laps and one lap at the end of a race. A friend of mine said to figure that use should hold enough fuel for at least 10 laps on a race course but then again I am using racing conditions as a source.

thanks!! that gives me an idea... looks like it's approx. 20-30% increase in fuel consumption.
