As George said, the article is available on the AMA website. The fuselage was built in two pieces because the wing is so thick. The wing was built, covered, etc. and the front end glued on, then the rear end. the top was either sheeted or planked. Today, I would mold a top. The plans were drawn by Frank Beatty and are a work of art.
The first one was crashed due to a line break. The wing and flaps survived (suggests that the wing is overbuilt). I still have the second one. Unfortunately, I painted it with unplasticized Aerogloss and it needs a complete recover job. Wingspan is 36 in, weight around 11 -12 oz. TD 049 on pressure. Flew it on 42 ft 008 lines. I don't fly hourglasses very well, but I flew a 40-pointer with the first airplane. Of course, I was alone at the field at the time.
