i think you are on the rite tack looking at the small gassers.glow fuel is getting higher in price everyday and glow engines prices are going down.i have more than a few saitos,ys's and can't even get less than half the new price for them.i have a Fusion with a ys110 and a Mojo with a ys63 and love it,but hate to pay the pice for 30% fuel. when your looking at a big block glow i think your better off with a gasser.
