WACO 10-550 fast aerobatic selflaunching sailplane Its design launch weight 42 oz generates wing loading 12 oz/sq ft design has clocked initial rate climb 4500 feet per minute using Casio altimeter

keep ducking away cutting edge resorted stiffening CyA glue shaving off razor blade worked Note also sanding KeyIa/epoxy doesnt give itch way sanding fiberglass does just wear off soft little fibers Keviar roll off skin pesky fibers made sneeze tells use face mask So after rough-sanding away fuse lage blemishes time some Sig Epoxolite didnt like wing-to-fuselage fit built fillet out Epoxolite Epoxolite first mixed like butter An hour later becomes stiff enough can wet finger smooth surface until becomes like glass Wait another two hours will rubbery can minor surgery sharp knife scissors Wait another three hours will hard week-old bagel can saw file grind Dremel tool generally treat like wood Next something done about rough surfaces Keviar cloth came through epoxy after sandpapering Keviar cloth very coarse compared fiberglass know its because catches skin run finger over tried Squadron Green Putty filler didnt work very well Fellow SEFLI Silent Electric Fliers Long Island club member Steve Anthony put wise idea wipe acetone softens epoxy enough give Green Putty pretty good grip Frank told Cyanoacrylate CyA adhesive loves Kevlar skin recommended Bob Smith Industries Super-Gold CyA talked about September 92 issue adhesive made structural installations extrathick gap-filling odorless Maxi-Cure variety 10- 25-second-hardening worked great Inspiration Use gap-filling CyA glue filler spread smooth possible using glue bottle nozzle squeegee let cure Spraying hardener just makes lumps must grind off afterward also dissolves blue foam under Keviar few hours later sleeping Grinding down hardened CyA No 400 wet/dry sandpaper used wet hard work resorted scraping off high spots file used singleedge razor blade held perpendicular surface made short work lumps Wet sanding No 400 emery cloth produced very tough smooth surface similar Plexiglass stops bullets know treatment quick inexpensive light Bob Smith CyA bottle marked /2 ounce 142 grams verified weighing
