I use Radio south 1/4 scale hinges, and have found that they are superior to any other CA hinges on the market. I have tried Sig, GP (Both precut and cut your hinge material). The Radio South will not seperate from the mylar material like Sig and GP's will. I have experimented, and the only way I could break the Radio south's is with a vice grip, and then it still did not delaminate like the others.
