The 16oz. Du-Bro tank is a perfect fit! I will add in in some padding material for the tank to sit on & it's ready to go. Notice the hole for the engine mounting bolt just forward of the tank. The Du-Bro piece is perfect here as the notched front of the tank clears the bolt area like it was made for it. In this pic you can also see where I added a few strips of triangle shaped balsa stock to give a little more deck tie in area.
