BPA pattern hinges?
 

What hinges are people using mostly? CA? Robart, or the old fashioned pin hinges? I think Goldberg still makes the pins, but I have not used them in a while. Wings are foam core, and do not want to risk CA-ing the foam away.
I also want minimal gap to seal.

I was toying with making the leading edge of say the rudder round, and making a concave post. Keeping turbulence out of the hinge joint. Thoughts? or just go with the 45 Bevel?

Thanks!

Full size DuBro pin hinges and hinges countersunk for zero gap fit.

Sounds like a winner to me, Thanks!

I used to be a fan of Kraft nylon hinges (no pins). I still would be, if someone made them available. I haven't checked lately.

I have nothing against CA hingest for .60 sized models of the SPA type that we are flying. Yes, you have to keep a careful eye on them, but I haven't had one fail as yet. Were this question directed at BPA type models, which it turns out to have been :), I would probably not recommend CA hinges. Just me, I suppose.

I like pinned hinges, recessed for zero gap.

I would too if I could build a straight wing that never warps, but all of my wings eventually warp, making a bind when pinned hinges are used.
