The gist is to start w/ the radius of the standard fairing just forward of the spar and extend the tangent point aft along the fuselage waterline until abeam of the flap trailing edge. My intention is to cut the supplied fairing just forward of the spar and increase the radius aft as shown in the pixs. I plan to have a lapped joint at the trailing edge of the wing (not the flap) and secure the new fairing aft of the wing to the fuselage, overlapping the flap; the fairing forward of the trailing edge of the wing would be glassed to the wing in the normal manner. I anticipate placing the rear pip pin w/ the use of a modified set of needle-nosed pliers thru the standard hole. I have not resolved the issue of trailering as the projection from the fuselage will create a conflict when the wings are stored alongside, though I am hopeful that the spar carriers on the trailer can be relocated to provide clearance and still stay within the overall width limitation (8 feet) for highway travel. Might this be: Much ado about nothing?...a promising development?...beyond the pale? Thoughtful comments would be appreciated...especially from anyone qualified to opine about the aerodynamics of such an installation. thanks, Fred -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
