CANARDS flying wings As can tell quick glance photos month going look two exotic breeds model designs Canards flying wings un questionably interesting look definitely attention grabbing something simply looks unique configurations offer advantages cant found conventional designs Im going discuss few ideas ories behind canard flying wing well take look few planes available incorporate ideas flying wing people flying wing mildly intriguing nice diversion ordinary some us also much Seeing fly makes heart beat just little faster thoughts available performance make head swim What makes models special answer dragor precisely lack drag Im saying flying wings pro duce no drag obviously some created skin friction theres induced drag airfoil just amount produce rela tively low true flying wing all-flying wing has no surface other wing itself means modeler has no concerns about about wing-to-fuselage stab-to-fuselage fin-to-fuselage jointsor about shape fuselage Factors prime concern designer low-drag conventional airplane become least true flying wing virtu ally nonexistent few examples modified flying wings incorporate vertical fins ever effects drag have considered overall design What about having insignificant amount drag produces such significant advan Annihilator Almost five years research development have gone canard Slope Racer prototype should exist end
