This is not a reply...just another Idea. If I was going for a long distance run, I would place main fuel tank on C.G. Then use a small 2 oz hopper tank close to engine for consistant running. A pressure line from muffler or crankcase would pressurize main tank and shove fuel to small hopper tank. Then use a small carb off a .10 glow engine. Also it looks like Saito is going to have a smaller size ignition engine which may have great potential! Best regards, Capt,n
