MY fuel consumption depends on what I do. When I run my landmax (MP 7.5 based rally car) in the summer I'll run the thing for an hour straight in a parking lot. Then let it chill a bit while I break out my 1/8 buggy for a couple tanks. Then back to the Landmax for another hour. ITs just nice and relaxing for me to run long periods of time like that but with a .21 or lerger engine on all my Rc's doing the long runs I end up using almost a gallon in a day.
