CONTROL LINE AEROBATICS WHEN THINK big competitive events such Nationals Team Trials Vintage Stunt Championships etc people usually come mind winners unusual performers However Id like express gratitude behalf Stunt community volunteers make competitions happen events running efficiently tribute dedication talent selflessness Warren Tiahrt Bruce Gifford JoAnn Keville Shareen Fancher Lila Lee superior cadre judgesled trained years Dave Cook Gary McClellanare few As reflect 1997 competition remember results reflect what flier did what expected same opportunity everyone else Celebrate competition its best its ever keeps getting better because dedicated volunteers read editorial Home Shop Machinist discussed longtime contributor died left legacy always trying extend himself projects similar experiences years ago Martin Baker MB-5 1977 design well beyond project ever attempted Rabe-type molded-shell fuselage dihedral wing shock gear never done things required make design fly major fixtures construct new techniques jigs accurate scalelike finish apply associated detailing Time required complete model estimated 800 hours above light Looking back 20 years Id say MB-5 made much competitive flier As result lierally being forced things correctlysuch accurate fuselage fully-sheeted jigged built-up wings ultralight weightI elevated building skills develop correct paint scheme involved proportioning markings because airplane stylized true Scale Mixing applying epoxy colors matter research aided Keith Trostle probably world expert MB-5 tutorial competitive Stunt construction
