RE: 1/2A trainer anyone?
Yes it's a mini Kadet.
I drew an optional fin and the rib layout. I'm just going off of pictures, so I may not have the fin exact. I still have to draw the spar and LE cutouts on the ribs etc. I was going to go with a Clark Y airfoil, but I decided to use an airfoil that could be built flat on the workbench.
