bhI U Windy Urtnowski & Joe Adamusko Joe Adamusko have shared love Spitfires years spring 1995 committed what ultimately Spitfire Project Little did realize just all-consuming project would become people would contribute significantly final outcome Bob Martens created finest sets drawings CL Stunter did drawings actual parts templates used construct original two Spitfire models Ed Gallagher instrumental composite material work expert machining spinner male molds backplates Ron Kieffer anodizing George Venturini vacuumforming canopies done Dave Midgley As design evolving went back forth almost endlessly Joe drew up plans postman commented increase mail spring Joe massaged drawings made changes eventually arrived design see didnt come easily cheaply quickly result exactly what minds eyes beginning airfoil pure Patternmaster Big Jim Greenaway designer Pattemmaster has gift fine wing design help feedback instrumental finalizing aspects Spitfires areas force arrangements wanted
