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.  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.
