ET-20 trainer by Bob Martin


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.
