The design for the horizontal tail surface is based upon the conventional tail design option for the stock Cruiser aircraft with some Vision aircraft thrown in. While the vertical tail surface needed to be enlarged, the horizontal surface was reasonably sized after the 24" aft fuselage extension was included. Both of the tail surfaces differ from the Cruiser conventional tail option in that they use the NACA 0010-64 airfoil. This is a variation on the very common NACA 0010 that shifts the point of maximum thickness aft so a deeper spar can be used to provide greater strength.

3) The design for the mold that will form the horizontal tail is based on using a wooden frame to support a sheet of Formica type counter top laminate. The concept should be rigid enough to allow for vacuum bagging without distortion. If needed additional wooden reinforcement will be added to the underside of the mold form. This single mold will be used to form the bottom skin and after it has been removed, it will be used to form the top skin and place all of the ribs and spars in place. The connections between the HS aft spar and the elevator spar can be made during construction and after it has all been removed from the mold, the built in cut lines will be followed to separate the two parts. With a little bit of finishing the HT will be ready for mounting. This construction technique is simpler than what the Vision plans call for and should result in a part with minimal weight.
