If you are a DIE HARD CA fan, go ahead with some Ca hinges. But along with many others i would recommend the robarts. Just drill a hole(bit and key included with the hinges, 12 buck at hobbytown and 15 hinges) and put some epoxy in it and stick it in. Prit-tea easy.........You arent going to run into trouble here. also if you go with any hinge but a clear peice of monocote or trim sealent on the TE and The control surface. Just in case it fails( you cant see it and its like insurance for you 200+ hour Kit) Good luck with the kit!
