The Dragonfly was designed by Harry Grogan for the AMA A-1 Towline Glider rules in 1972.  At that time the rules specified a minimum weight of 145 gms. (5.1 oz.), a maximum total projected area of 279 sq.in, and a 50 meter towline.  In the late 1970’s, AMA adopted the FAI rules for F1H.  This increased the minimum weight to 220 gms. (7.75 oz.).  That made a huge difference.  Modern F1H models are complicated carbon fiber reinforced circle tow bunters.  Today the Dragonfly is not really competitive in F1H but great as a vintage TLG and for the popular Hi-Start event.  Model has a 48 1/2″ span and 274 sq. in. area.  Flying weight of our model is 161 grams (5.7 oz.) including tracker, and it loves thermals.  Contest record includes a 2nd place in the 1974 USFFC, 3rd at the 1975 NATS, and 3rd at the 1978 USFFC in A-1 glider.  Model also took 1st place in F1H at the 1996 King Orange Internationals.
