Dan and Rachel Weseman, SPA/Panther people, are now testing their latest development in flying Corvairs, a 3.3 liter engine featuring one of their USA made billet crankshafts, with the stroke increased by .312″. This in combination with the same bore as a 3,000 cc Corvair yields 3.3 liters, or 200 cubic inches.
They test ran the engine a week before Oshkosh, and brought it to display in their booth. It brought a great deal of interest. If you would like to learn more, follow this link, it includes a video Rachel made of the engine on it’s first run:
Above, Dan and Rachel stand on either side of their 3.3 engine at Oshkosh. It was mounted on the front of Paul Salter’s Panther, which is 90% complete. SPA/Panther reached a milestone this week, as the first customer built Panther, built by Bob Woolley, went for a perfect test flight.
