The twin-engine Fokker T.V (T-5) was drawn-up from 3-views in an obscure aviation magazine in 1976. The tri-motor Stinson 'U' was drawn-up from Wylam 3-views in 1989. Easy to do. Just a ruler, some pencils and a large sheet of paper. The Fokker was mainly 1/4" sheet (fuselage, wing & nacelles) with 1/8" sheet tail group. Nacelles were faced with 1/32" ply. Cox TD power. The Stinson spanned 50", had a 1/2" balsa fuselage (WAY too heavy), built-up tail surfaces, sliced-rib wing construction, and three Cox reed-valve .049s. Ideas for that one were sketched-out aboard a TWA L-1011 enroute from LAX to Boston. Both models were featured as construction articles in the now-defunct 'Model Builder' magazine.
