On further checking my old files, I came up with the following - remembering that the Tripehound was to be one of my pet projects 10 or more years ago when the Shuttleworth Museum got their flying reproduction. However, Pete McDermott beat me to it and built a 1/4 scale version of it (think about it - a 25% scale version of a 100% reproduction !) so I lost interest. However, by that time, I had gathered together some info and I offer it to you here :-

* Mike Booth's 1/4 scale construction plan - either from Mike Booth or Mick Reeves in UK
*Windsock DataFile 22 - Sopwith Triplane
*Windsock International, Vol 6, No 4, Jul/Aug 1990 - about the Shuttleworth repro and description of Pete McDermott's 1/4 scale World Champs winning model with his flying notes
*Rand McNally's "World Aircraft Origins - WW1", Angelucci & Matricardi
*Ian Allan's "Vintage Aircraft of the World", Gordon Riley

Enjoy ! MalcolmL
