This 1917 Sopwith Pup was built by Andrew from an (English) Flair Kit. Span 60 in. Power OS 91 4-stroke.
A robust and reliable performer, this Pup flew over 40 hours at the SAM 27 field. This is longer than some of them lasted in 1917.
The Pup was a pleasing airplane to fly -- light and maneuverable -- in fact the first decent airplane many pilots had ever flown in WWI.
