The Rihn DR-107 One Design is an American aerobatic homebuilt aircraft that was designed by Dan Rihn and first flown in 1993. The aircraft is supplied by Aircraft Spruce & Specialty of Corona, California in the form of plans and a materials kit for amateur construction.[1] The DR-107 was designed as a low-cost one design aircraft for competition and sport basic to advanced aerobatics, including International Aerobatic Club Class One competitions. For this role it is stressed to +/-10g.[1] Design and developmentThe DR-107 is a monoplane that features a cantilever mid-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear with wheel pants and a single engine in tractor configuration.[1] The aircraft is predominantly made from wood, with some steel parts and doped aircraft fabric. Its {{convert|19.50|ft|m|1|abbr=on}} span wing employs a Wainfan 16% symmetrical airfoil and has a wing area of {{convert|75.55|sqft|m2|abbr=on}}. The wing has almost full-span ailerons that produce rolls of 360° per second. The wing has no flaps. Other features include a low-mounted cable-braced tailplane and a {{convert|24|in|cm|1|abbr=on}} wide cockpit.[1][2] The DR-107 can accept engines of {{convert|160|to|180|hp|kW|0|abbr=on}}. The standard engines used are the {{convert|180|hp|kW|0|abbr=on}} Lycoming O-360, modified with high compression pistons, an inverted oil system and fuel injection or the {{convert|160|hp|kW|0|abbr=on}} Lycoming AEIO-320 powerplant.[1] The aircraft has an empty weight of {{convert|740|lb|kg|abbr=on}} and a gross weight of {{convert|1150|lb|kg|abbr=on}}, giving a useful load of {{convert|410|lb|kg|abbr=on}}. With full fuel of {{convert|19|u.s.gal}} the payload is {{convert|296|lb|kg|abbr=on}}.[1] The designer estimates the construction time from the supplied materials kit as 2000 hours.[1] Operational historyBy 1998 the company reported that 355 kits had been sold and five aircraft were flying.[1] In November 2013 33 examples were registered in the United States with the Federal Aviation Administration, with another 11 previously registered and now removed.[3] Also in November 2013 there were two registered with Transport Canada and ten in the United Kingdom with the Civil Aviation Authority.[4][5] Specifications (DR-107){{Aircraft specs|ref=AeroCrafter and Lednicer[1][2] |prime units?=imp
