Did they cut the stab as a diamond? Can't tell by the photos. I buiilt one back in 74 or 75 and still have the plans and instructions for it. Yep, it was heavy.... Flew very fast and when I sold it, the new owner creamed it on the first flight! It will be interesting to follow the build and all up weight. I am working on enlarging the plans for a all balsa Nutcracker.
