Just an anecdote: I have a Super Tiger .90 (15cc) converted to run on gasoline. The other day I was flying it and I did a bunch of aerobatics, then about 20 touch and go landings, and then a bunch more aerobatics. I don't know how long I flew, but it was a long time. My brother said "That thing has GOT to be getting low on fuel." (It has a 12 oz. tank, just because that's what came with the plane.) When I checked, I had only used half of the tank of gas. Quite a difference, (and savings) from Glow Fuel!!
