Ed,

In most cases when you use CA type hinges you will get some surface movement at the hinge line since the hinges are not stiff. I have seen a jet loose its tail due to this surface movement, on a high speed pass we heard the flutter and .5 seconds later the tail came off. Flutter split the wood at the hinge line and the surface left the plane. There was NO slop in the linkage. I too use CA hinges on my giant scale planes but on my jets.....never!
