Hey Guy's
I thought I'd chime in on this subject.
I too have seen failures on the CA hinges and have chose not to use them.
I have been using Du-bro or Klett large scale size hinges.
I don't use the cotter pins or the pins that are flattend to retain them.
I remove these and use .047 music wire or the appropriate diameter as a continuous hinge pin thru all the hinges at once.
By bending the wire in a J configuration at the outboard end of the control surface
you can just press it in to the outside edge of the wing, horizontal or vertical and apply a
small drop of thin CA to retain it.
The nice thing with this set up, if by chance you do have a failure you can just pull the wire
out and the leading edge of the control surface and the trailing edge of the wing, vertical stab or horizontal is exposed and a lot easier to take the broken part out.
Good luck.
