This is a little-known plan for a really dandy looking 20 size trainer. The plan shows a 1/16″ balsa crutch, and 1/16″ balsa windshield and back window. I’ve reworked it to have lite ply tab and slot construction throughout the entire fuselage. The leading edges are 5/16″ dowel or arrow shaft. No specific dihedral angle is noted on the plan, so I’m including a 2 degree dihedral brace. Sounds good to me, but if you want more or less dihedral let me know.
