I"ll second the ca hinge hate! what junk. My wife got me a corsair with the ca hinges and when i landed from the first flight 2 aleron & 3 elevator hinges were torn in half. I am just getting back into this and went back to the old method of pinning my hinges. I used to use tooth picks cut flush with the stab/wing but now just use regular straight pins and have had no problems.
