I had some troubles with mine as well but found that if you put the hinges in the fin first and then insert the bottom of the rudder at an angle to clear the fin you can insert the rest of the hinges a little easier, clear as mud? I am looking forward to your speed brake hinging, I have been thinking a lot about it since Paul mentioned the pitch/roll problem. I was thinking of moving the hinges as far outboard from the center as possible to give it that sturdier platform that will resist twisting in flight. I can imagine that it is going to take a bit of engineering to get it this way due to the curvature of the fuselage but hey, that is the fun stuff anyway!
