[1][2] 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.
[1] The aircraft was not a commercial success, production was halted and the company went out of business in about 2004.
