The Preiss RHJ-8 is a homebuilt side-by-side two-seat flapped glider. It is an evolution of the Preiss RHJ-7 developed from a Schreder HP-14. The wingspan was slightly increased, the tail changed to a T-configuration with high set stabilator, the undercarriage is partially retractable (modified by some builders to be fully retractable) and the large canopy swings open to the back with the help of an external strut.
