Wow. I am nothing less than conflicted about all these opinions! So I think here's my plan: I'm going to try again with nylon hinges, using hinge glue which I bought tonight from my hobby store, and seal the gaps with Ultracote per KenRC's method. It's just a trainer and I'm a newbie, no aerobatics planned for this summer. If and/or when I have an aileron disconnect due to hinges, I guess I'll form an opinion after CSI-ing the wreckage. LOL.

Meanwhile I think I'll worry more about learning gentle turns and landing my tame trainer with the help of an instructor. Thanks for everyone's opinions!
