On the kit plan , the front ( underwing ) 1/2 " Sht. is drawn SOLID , The line from the rear raked 1/2 ' underside DOES NOT continue forward to the underside of the underwing block .
DRAFTSMANS ERROR . ( Noteably the TRACERS , tracers being twerps incapeable of configureing drawings , usually )
Hence the 1/2 in. step , to a ' plan built ' giese Nobler / Top flite . If they used thinned PVA theyed probably spot it . Useing super glues probly the most mentally dysfunctioning .
