The PT-60 was my first kit.

I asked my instructor about the washout. I was concerned about being able to get both wings the same. He told me to just keep the wings flat on the table and not try to build in the washout. He said the plane is so stable it's just not needed. I built them flat and the plane flew great.

I built the 'sport' wing with lower dihedral. The book called for 4 inches. When I started fitting everything it all lined up with about 3.5 inches so I stopped sanding and joined the wings with 3.5 inches.
