Very rare type! The Bora had a tragic ending.
I have done quite a bit of research on the Bora for my new website as it is loosely related to KARI's later efforts with the FireFly, a joint effort with U.S. company Proxy Aviation Systems. It was quite a challenge because most sources were in Korean and very scarce as the Bora is an unpleasant episode that few Korean sites wish to dwell upon...
The KARI FireFly was developed by the Korean Aerospace Research Institute, from a Velocity XL fuselage with shorter wings, no winglets, twin fins on separate tail booms, using both local and US parts. The FireFly was used as a demonstrator at Velocity's plant in Florida, then flown on a South American/South Pole exploration flight.
KARI simultaneously worked on an alternate design, an original Korean prototype named the Bora (Greek for "northern wind"). Developed with Korean ultralight manufacturer Sung Jun Motoravia, the Bora had similar overall configuration but with cranked forward swept wings and joined tail fins (pi-tail). It crashed fatally in 2004 during its test flight, killing its two pilots, both respected veterans in their field. Investigations showed that the pi-tail was structurally weak and entered into deep vibration during flight. This probably caused the composite structure to break in flight, although it is also possible that the aircraft simply stalled as a consequence of deep vibration and the pilots couldn't recover it.
The last picture shows both the FireFly and the Bora for comparison purposes.
