Incorrect for the vertical the leading edge and spar were made from furring strips. The outer was door skins stapled and glued to the firing strips. The core was three cell cardboard glued inside cut into ribs. Then the door skins were pulled together over the ribs to form the trailing edge of the airfoil.
The HS was made from a furing strip going through the vertical that was stapled and glued as well. This formed the leading edge which in early ones dad put urethane foam and wrapped in glass
The entire crucifix was then filled in with Bondo sanded down until smooth and then painted the color. The customer wanted. Otherwise, it was the company colors of yellow with black trim. Later, he started making horizontal stabilizer of skins as well. The problem was trying to ship that thing it took up too much cubic space the shipping cost on it was more than the tail cost.
He wanted to find another way to make them so they could be shipped without the wings on them so they wouldn’t be so exorbitantly expensive to ship so he and Dick came up with the metal tail that was sold up until he went out of business. The nice thing about that is the wings came unassembled with the metal sticking through and all the customer had to do was slide it on and pop rivet it.
