HELLO Slope Soaring enthusiasts last column started fairly long introduction months column going jump right meat subject discuss some information about models construction techniques designs have forwarded Slope Soaring enthusiasts first genfleman drop line Englishman Mr Graham Woods long-time Soaring devotee obviously very good builder enclosed picture Slope aerobatic ship included some very clever construction detail want share First model composite creation built various composite materials wrapped around fuselage produced cottage industry Viking Models Vikings owner Jerry Slates master craftsman comes composite molded construction Jerry turns out extremely high-quality product very reasonably priced Smoothy fuselage just high quality both fiberglass new aramid fiber called Spectra Allied Signal Corporation product touted being significantly stronger lighter Kevlar So Smoothy fuselage durable yet quite light Next Graham builds all-composite wing foam-cored wing graphite cloth fiberglass bonded epoxy resin Graham says wing uses 125 gin2 369 oz/sq yd 41 twill carbon veil 25 gin2 74 oz/sq yd E-glass epoxy-glass no spars say uses process putting lightweight E-glass Mylar transfer sheet first top lays lamination 37-oz woven graphite fiber cloth after uses squeegee system impregnate cloth resin veil acts eliminate pattern may show through weave carbon helps reduce pinholes can occur vacuum-bagging After process applying cloths resin Mylar transfer sheets complete sheets applied foam core vacuum-bagged down Note Graham does use spar vacuum bag arent familiar process used apply pressure Mylar result pressure hold composites resin foam core epoxy resin cures after resin cures wing removed vacuum bag Mylar transfer sheets pealed composites process yields super-smooth finish both light strong As aside Graham goes say about 5G wings bend little Im careful pulling out loops pylon turns Ill just bet dont bend very much Graham doesnt tell elevator rudder
