The Winchester Skonkwerks Ultralight Research and Development Facility — let’s shorten that to Skonkwerks — represents a team from Larsen, Wisconsin. Skonkwerks honored Alberto Santos Dumont by first building a 23 Bis and later the 24 Bis. The group describes itself as a “loosely knit organization of friends, flyers, and fanatics… tinkerers, builders, and bullsh###rs. We are engineers, designers, and dreamers hanging out in a little hangar screwing stuff together and making it fly.”
Lee Fischer was the founder of this group of tinkerers that formed after he first showed a highly modified Robertson B1-RD. So much interest was shown in the Demoiselle style of aircraft that he decided to build a 23 Bis. At AirVenture 2015, his friend Mark Solper hinted that it would be “great project to build a pair of ‘evolved’ Demoiselles for a subsequent AirVenture.” This suggestion led to the 24 Bis
