Subsequently HTC was renamed Tri-R Technologies and the composite kit plane was marketed to the homebuilt constructor. A tailwheel version, the KIS TR-1C (initially known as the KIS TD), was introduced in 1992, while kit deliveries started in 1993. It could be fitted with an 80 to 150 hp engine, and for storage, the wings could be detached easily. The first tail wheel aircraft was built in the USA in 1993 by Chuck Harrison with an O-235 engine The aircraft of Ken McCormick (flown June 1993) had a Subaru Legacy EJ22 engine and was the first to carry the TR-1C designation. The four-seat KIS Cruiser TR-4 was also developed.
In 2001 the Pulsar Aircraft Company (formed in 1999) acquired the design and production rights of Tri-R, while the latter still produced the composite parts. The two-seat KIS TR-1 was re-designated Pulsar 150, while the KIS Cruiser became the Pulsar Super Cruiser. In 2005 all aircraft production was transferred to Ilopango, El Salvador.
To celebrate a century of powered flight, Ray Clagg and Nick Ridden flew KIS Cruiser G-BYZD from Netherthorpe, UK, to Oshkosh (via Iceland) in July 2003, the first British homebuilt to cross the Atlantic. Unfortunately G-BYZD was consumed by fire on July 4, 2008, after it crash-landed near Near Upfield Farm, Whitson, UK, due to power loss on takeoff. Pilot and passenger escaped injuries.
G-OKMA was built by Keith Miller of Coventry, UK, and powered by a Continental IO-240-B1B the aircraft flew for the first time on August 8, 2008, after 7 years 5 months and 5 days of part-time work. By December 31, 2012 the two-seater had flown 470 hours.
