other end place both ends over index finger Pull out now 4-stranded motor several times until looks nicely braided Install motor plane test glide over tall grass glide reasonable try few winds launch plane slightly nose down everything still OK try about 30 winder turns Fiat flies large left circle left glide properly trimmed will fly slightly nose-up attitude glide very well braided motor fly fun

Hutchinson continued page 45 quickly short useful lifetime Use about three coats nitrate dope clear epoxy final coat Give couple extra coats front portion stab since exhaust residue seems collect Fuselage Use metal straightedge cut Out sides add nose tail doublers Draw top view out piece 3/32 sheet dont cut out yet Pin bottom building board glue formers Hot Stuff works well fuselage construction Add sides check ing carefully alignment Sand fuselage assembly add top Build pylon gluing pylon core bottom ribs Add formers checking core truly vertical Add tip ribs sand cover 1/20 sheet fin built same way no central core needed Cut out two sides outline shown glue fin ribs side Hot Stuff Sand no rib edges stick out glue other side recommend epoxy finish like Hobbypoxy fuselage High-nitro fuels will destroy other finish very short time Cover fuselage tissue using nitrate dope better epoxy adhesion Apply couple coats nitrate lacquer sanding sealer two coats colored epoxy add additional coat epoxy front end Wet sand first coat #400 wet-or-dry sandpaper final coat #600 Rub out Dupont white polishFlying Dont too much hurry get out flying field Assemble model check thoroughly proper balance correct warps CG should shown plans balances tail-heavy move engine forward inserting additional plywood spacers between firewall engine mount engine should point straight ahead slightly left Hand glide model sure theres no stalling diving tendency Correct shimming front back stab pieces thin ply should definite glide circle right Run engine few times familiarize yourself pacifier fuel system make sure engine cutoff works first flight try 5-second run prop backwards engine running full bore probably wont tell much should get rid first flight jitters model does anything climb straight out shallow angle may have problems sharp turn may mean have misaligned rudder bent fuselage steep climb stage means have too much incidence now flights will made full power prop proper direction Reason hot free-flight pattern depends being trimmed certain speed various adjustments make deli cately balanced work against other properly maximum climb speed try work way up gradually power 11 find yourself undoing low speed adjust ments go along So bite bullet try full-power test fight about 3-second engine run model should climb straight Out steep angle Adjust thrust offset correct turning tendencies right launch Remove incidence model shows looping tendency short run has shallow climb angle nose begins tuck under add incidence shimming rear stab get going straight out no looping tendencies 3-second run increase engine run 2-second increments model tends go left longer engine runs add right rudder tab Use pieces 1/16 x balsa cut trailing edge section glued February 1980 125 ing compound Assemble complete model move pylon until ship balances indicated very slightly forward epoxy place
