Brian Coughlin flew his Fokker D.VIII replica equipped with an original 160-hp rotary Gnome engine at Old Rhinebek Aerodrome last weekend. Coughlin built the aircraft in the early 1990s before selling it to Kermit Weeks’ Fantasy of Flight. He purchased the aircraft back in July of this year and equipped it with an overhauled Gnome engine and period instruments.
The unique sound of the rotary engine can be heard in this short video..
