<div style="margin: 0in 0in 10pt"><span style="line-height: 115%; font-size: 9pt">Well, Igot the top of the wing sheeted, using the thick CA method up front and the Titebond II iron-on method on the trailing edge. I think both methods are equally well suited. The substrate would fail before the joint on both, and the thick CA is positionable enough.The CAdoes grab pretty quick, but I think it could be pulled apart if you needed to if you stayed inside 20 seconds or so. The iron-on method is very good, but takes a lot of time waiting an hour for the glue to dry. I will reserve that method for larger, more critical sheeting.

This photo shows the servo bed design for mounting the twin servos in the lower wing. Ichose to move them on out an additional rib from the location where the bell crank is on the plan. I am not sure if was necessary, but I would rather have the aerilon activated closer to the center rather than offset to one side.

Also, note that the servo is rotated slightly to make the pushrod to line up perpendicular to the hinge. Subtle, but with the swept wing and the ribs running straight along the axis of the fuse,rotating the servo keeps the pushrod moving axially only, preventing bending of the control horn on the aerilon.

I don't know if that makes things more clear or muddies the water...



That is not a good angle to explain why I turned the servo slightly. I will get a shot tomorrow from a birds eye view, which will make my point much more clear. </span></div>
