2001: The Polen Special set the FAI Class C-1.b (takeoff weight 500 to 1000 kg) speed record of 303.4 mph (488.3 km/h) for a 500 km (310 mi) circuit; the record still stands in 2022. (The Flying article says it flew 360 miles between Oshkosh and Monticello IA in 70 min 03 sec.) Pilot-owner Richard C. Keyt won the Blériot medal for the effort.
