07/31/2009. Remarks by Walter van Tilborg: "Ken Long completed his original designed single-seat SR-10JKL in 1994 after work had started five years earlier. The aircraft was a scaled-down replica of the Stinson SR-10 and was powered by a 46 hp Rotax 503 two-stroke engine. The official first flight date was June 18, 1994, but it had already left the runway (during high-speed trials) a couple of days earlier on June 12."
