Designed as a manned version of the Fi 157 radio-controlled drone, the Fi 158 was a low-winged monoplane built largely of wood, with retractable tailwheel undercarriage and twin fins and rudders, with the crew sat in tandem in an enclosed cabin. Limited flight testing was carried out before the prototype was destroyed in an air raid.
