The Preiss RHJ-8 is a homebuilt side-by-side two-seat flapped glider. It is an evolution of the Preiss RHJ-7, which was developed from a Schreder HP-14. First flown in 1970. The wingspan was slightly increased and the empennage was changed to a T-configuration, with the stabilator mounted atop the vertical stabilizer. The undercarriage is partially retractable (modified by some builders to be fully retractable) and the large canopy swings open to the rear.
