In 1966 Preiss converted a Schreder HP-14 into a 2-place ship with side-by-side seating (two sets of rudder pedals and a center control stick with a bar that swings from one side to the other) and a fixed landing wheel. The design used standard HP-14 wings with a 2-ft center section added in the fuselage.
