The Graupner Clou kit from mid 60s, provided wood for both a 74.5 in wing (labeled "aerobatic wing") and an 99 ~ in. "thermal" wing. Many early American kits followed fit. I.e., Malibu 76". Monterey 100",Aquila 99.9", Drifter 72", Windrifter 99.8",Hobie Hawk 99", Windfree 99.25", Wanderer 76" &99", Todi 76" or 100" . And several followed form as well. :-) I am not sure just when the 2 meter class became codified. There was only one class at the first LSF contest (1971) - held at the Nelson glider ranch, Livermore, Ca. BTW, that same year, an early form of f3b was flown at the NBSS contest in Santa Rosa, Ca.
