Paraborne Backplane

As production of the Daiichi Kosho Whisper, for which Paraborne acted as US distributor, came to a close, the company developed its own derivative design, replacing the Daiichi Kosho DK 472 engine with a Hirth powerplant of similar output.^[1][2]

The Backplane was designed to comply with the US FAR 103 Ultralight Vehicles rules. It features a paraglider-style high wing, single-place accommodation and a single 22 hp (16 kW) Hirth F-33 engine in pusher configuration. Original factory canopy options included the Ranger or the Seal designs. As is the case with all paramotors, takeoff and landing is accomplished on foot.^[1]

The aircraft was not a commercial success, production was halted and the company went out of business in about 2004.^[2]
