Swearingen SX-300

An high-performance homebuilt aircraft featuring two seats and developed by Ed Swearingen of San Antonio, Texas during the 1980s. The aircraft was offered as a kit, but the kit was not a comprehensive kit like contemporary designs and its construction was beyond the abilities of the average amateur aircraft builder. The plane featured a 300 horsepower (220 kW) six cylinder engine. Plans have been made to revive the plane and offer it as a quick-build kit, but there is no current kit being offered.
