capabilities Construction notes Since Cassutt conforms precepts profile construction wont go great amount detail put thing together some areas need touched upon wing heart airplane Regard less fuselage constructed profile built-up foam whatever plane will fly well wing built word wise sufficient Ribs can stack-sawn 3/32 balsa two separate stacks Lightening holes lead-out holes should

trailing edge cap strip 1/16 trailing edge pieces both need doublers splice joint strength Begin construction pinning bottom TE piece over plan gluing ribs place used Goldbergs Jet instead aliphatic resin frequently use put entire wing together less 30 minutes ribs set place glue top TE piece poking pin holes through rib location squirting drop Jet through pin hole Spars next favorite method ensuring warp-free wing pin bottom spar plan setbut dont glue ribs over glue top spar top spar firmly anchored place turn wing over treat bottom spar same fashion Now add LE TE cap strip way getting adequate pressure LE notched rib assembly like cut six 4-in sticks spruce can use popsicle sticks dont want waste wood space vertically equally behind wing spars Use several rubberbands Loop around
