since wee lad Early influences obviously focus Lee Hines Sweepette 20 Tony Slaters 18m Slarmi Aeromodeller Plans Ser vicelong fuselage underslung fin think Ive taken chuck gliders model event ever attended flew CL Combat always something fly run around after between competition flights Typically England always blowing half gale usually entered chuck glider just too windy fly anything else background prefer large models have flown some 24 x 5 wings stability turbulence pri marily visibility air down wind after landing long flights windy day dont believe lose too much altitude using larger model especially since have superior glide find large gliders likely glide way out trouble make mistake An 18-in model typically puts ground quicker sackful spanners miss core thermal Ive always preferred weighty models its rough weather Personally think heavier model throws better Nothing worse almost ripping off arm overthrowing real lightweight England always used drop-off weights dethermalize DT no prob lembut California thermals play keeps lost several models tried manner tip-up tails hinge methods could never get really con sistent flights think pop-up tails never seat exactly same twice Also use potentially dangerous trim setup right launch washin inboard right-hand panel model gliding left may sound like spiral dive waiting happen its great trim ming throw part climbjust like Power model rolling left turning right glide just like Rubber model trimmed fly right/left using side thrust against warp Any stalls poor trim turbulence tend wing-over wind transition smooth glide still giving chance good flight best models using warp tail tilt give left glide have always needed just touch right rudder hold glide open opposite rudder comes stronger model tightens-up strong lift prevents spinning-in see aliens things differently As Chuckies finely-tuned mi nute adjustments stabilizer rud der naturally keen find DT method would leave surfaces firmly placehence pop-up wing surprised effective type DT Chucky no doubt saved model flyaway several times during US FF Champs typically DTing 240 300 min flight despite chasing motorbike some big thermals model specked-out overhead perhaps 1000 ft DT model looks though has self-destructed wing remaining horizontal nose dropping 450 sticking tail high air conveniently out harms way hits ground pop-up wing brought model down out thermals faster mouthful roofing nails Stan Stoy immediately spotted further benefit nomadic jet-setting Chucky flier Simply removing hinge pin wing comes off making model very transportable suitcase Just drop Hot Stuff gives temporary pinfixing days flying arrival youre looking history particular model hold tight built Wednesday evening flew hour Thursday night US FF
