For what it's worth, here's my experience with CA hinges. I've had them on a GP 1.20-sized Super Sportster, the Midwest At-6 (84" WS), and the Midwest Extra (80" WS). All had over 100 flights. On all three I just inserted the hinge and applied CA to both sides. Didn't have any failures. I'm putting together the GP Wagstaff Extra and am using the CA hinges. This time I thought I would try putting a thin line using a white crayon at the center line of the hinge. After applying the CA it does seem that the hinge is left more flexible. Haven't flown the plane yet but I don't have any reason to belief the bond is any less secure because the area with the crayon is very narrow. Just my .02.
