After I glued the horizontal & vertical stabilizers together I realized that it was a flimsy arrangement. The vertical stab is nearly 12″ tall with no other means of support other than the glue joint. I saw a few YouTube videos of other 200% Jupiter Ducks that had struts on both the tail surfaces and wing tips. So i came up with this way of adding struts to the tail. Used coffee stirrers and BBQ skewers. The large black triangles pictured hold the vertical stab at right angles to the horizontal stab while the glue dries. How did it work? Way better!
