Having taken my cowling off and on about 15 times in the last couple months, the Phillips screws get chewed up pretty good. The Robby screws would be infinitely better I would think -- certainly cosmetically they would look better after many de-cowlings. Is the main reason because the Robertson screws are Canadian and the Phillips are US and the airplanes are US? Or is there a technical (or other) reason we don't use them? -Dico --e89a8fb2077056da0904cee3a638 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hi All,
