Heat Seeker

seat Seeker sailplane everyone can built aileron airplane rudder controlled polyhedral can 114 122 inches wingspan versions sheeted over built-up wings stab sheeted over foam wanted design new model modem-looking lines didnt want go whole-hog high-tech also didnt want have plunk out 400 800 bucks new sailplane modelers still like build using traditional construction methods designed Heat Seeker around standard planform tried clean up much possible elected reduce Scooters airfoil thickness 12% 11% maintaining same mean camber MC left MC about 33% halfway between well-known S3021 5D7032 Its good past ten years change airfoils have placed first AMA Nats total five times cant too bad So far Heat Seeker has placed first SMT 1992 1993 LSF Championships flown John Gunsaullus plans show basic built-up wing tail surfaces completely sheeted would rather cut foam cores templates also shown first thing people notice light stab have ever flown free flight hand launched gliders have seen drawings HLGs magazines will notice small skinny fuselage gliders really get bounced around breaking Because stabs rudder built thin light less stress fuselage So decide build Heat Seeker dont use solid sheet save time Keep stabs rudder light possible spars stab primarily keep ribs falling over webs give place hold stab during installation removal use eight-inch-wide 1/16 wing sheeting Superior Aircraft hate splice narrow sheets together foam templates shown also 1/16 sheeting wish use thinner obechi will have modify templates have Chuck Andersons airfoil program can select airfoil Scoot 33 reduce 11% plot skin thickness desire number small details shown drawings because everyone has own way doing things instance cut small slot top fuselage have access wing screw-eye retainer hooks some modelers prefer tape wings fuselage try film-covered wing film will pull away sheeting eliminate problem wrap clear 3M tape around last May1994 31 Right Plug-in section receiver accessible nose cone
