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.

A development of the Preiss RHJ-8 (itself a T-tailed, larger span, improved version of the RHJ-7), the RHJ-9 is similar to its predecessors, but with a larger span wing. The wing has foam ribs bonded to the aluminum spar and skins. It first flew in 1978.
