All my fuel is in the outboard wing panels only, 12.5 gallon each side. They start at the root and extend to the 36 inch rib at the end of the wing. They extend just 10 inches behind the forward spar. That puts them so close to the C.G. that my C.G. changes just one inch from full to empty tanks. If you are only looking for 6 or 7 gallon per side you could make them even narrower and longer and keep them right on the C.G. Install some good baffles to avoid slosh and you won't even know they are out there. Off net for the next three days. Have a good holiday............... Larry Flesner
