Walnut Scale is what I have heard referrers to models under 19 inch wing span. I know that Dumas Model's uses the term to describe their models. Anyway I like the term Walnut Scale so I decided to go ahead and borrow it. Although still a small model the wing loading allows for the use of some decent wood sizes.
This build I decided to go "Full Circle" and go to where I started; Yeap the good ole Guillows 500 Series. With the benefit of hindsight; I wish I had started with the 900 Series kits. I decided to take the learning curve I have acquired and apply it to a 500 Series kit build. I decided to go back to where I left off and that would be kit 508 the Rufe built as a Zero.
