OTOH I can fly my Something Extra with the Saito 72 on it for about 20 minutes on an 8 or 10 ounce tank. I always have at least half a tank left when I land, and I don't putter around, I have it firewalled a lot.
If you have 1/4 of a 14 oz tank left after 5 minutes run of your 125 then you have burned 10 1/2 oz. or 2.1 oz per minute. If you have 1/2 tank of a 10 oz tank left after 20 minutes run with your 72, you have burned 5 oz or 1/4 oz. per minute. Big difference. Is this correct? Just wanted clarification, I have neither one. Thanks
