The Firefly is a development of the Fournier RF6B. The RF6B first flew in March 1974, and Fournier built 45 RF6B100s powered by 75kW (100-hp) Rolls-Royce Continental O200 flat fours through to the early 1980s. In 1980 Fournier flew a more powerful development of the RF6B, the 87kW (116-hp) Lycoming O235 powered RF6B120. It was this aircraft that formed the basis for Slingsby’s T.67 Firefly.
