I would say use them. As long as you make sure you cut a little of the covering away from the hinge point and make sure you saturate the hinge on both side with Thin CA you should be alright. I've used plasitc hinges and robart hinges before in the past and don't like to use them. I have had bad CA hinges before but it was because of what they where made of in my older kits. The glue did not pentrate it at all. With the CA hinges being fiberous and the wood being fiberous you should have a good bond that will last. The guys in my club use CA hinges on their giant stingers with G62s and fly 3-d with them and never had a hinge failure. I did see a H9 Ultra Stick fly and have the ailerions rip out but after landing (yes he did save it) and on inspection it was found the Hinges never broke, The surrounding wood was way to soft and weak and that's what broke free. This just my opinion....LOL I'm building my TCraft now and I'm using the CA hinges that came with it. I have a ZDZ 40 for power.
