The BJ-1b Duster is a development of the earlier 41.5 ft. span BJ-1 Dynamite (designed by Ben Jansson and Hank Thor). Approximately 400 sets of plans and 150 component kits have been sold to homebuilders. The Duster is entirely skinned in plywood. In accordance with former OSTIV rules it has terminal-velocity-limiting dive brakes (216 kph/ 116 kt./ 134 mph. The Duster has been built in Canada and 10 other countries, and is type-certified in New Zealand. It is relatively simple to build but the 2.13 m./ 7 ft fixed center section provides a challenge for trailer design.
