Well guys and gals I had to glue a spacer 1/4 inch to the nose piece made it soft balsa, The spinner is two inch diameter. And will close a space. And maybe even help the balance situation. The top tank and engine cover will be a solid block of balsa. Like the Sterling Super Ringmaster. Getting close to finishing off this build. Last will be wrapping the lead out lines. Already plan on 58 foot lines. Thumb is healing but still have a ways to go. Slow process in your seventysAJ.
