Im gonna get in trouble for this, but, IMO, the hinges will serve you better if you place them in the garbage can and get some Dubro hinges or something else.
I just put a new 4* in last weekend due to ca hinge failure, the ones which came with the kit. The hinges, 5 of them broke into on the elevator.
I wouldnt listen to anyone regarding ca hinge failure prior to the crash, I thought if anything went wrong it was due to improper installation.
If and when you completely disregard this advice, you must inspect the hinges prior to EVERY flight, dont do as I did and become complacent because theyre ok every time you check, sure as you do, youll miss the one chance you get, maybe, to save your plane.
I installed ca's on 5 other planes with no problems, now, I find out another club member just had the same problem.
