There's nothing wrong with CA hinges. In fact, on a 40 size plane they are probably one of the better choices for hinging when we discuss them in context of the beginner's forum here. IMHO they are easier to install properly than the Hayes hinges you listed above. But if you choose the Hayes hinges, there is nothing wrong with them and will work for what you need them do do. The choice is yours, but if I were choosing between the two hinges in this installation I would choose the CA hinges.
