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. I also set it up for 2 degrees of dihedral per side, since no specific number is noted on the plan. Sounds good to me, but if you want more dihedral let me know.
