For me, I'm going to go either folded or not, don't really want to do half and half personally. I've still got some time to decide!
Dale, it can be a tricky fit, but with care it isn't too difficult to line up properly. The last one I built was a few years ago, so I don't recall any specific tips unfortunately, but the last two I've built have turned out nice and even. The first two I built? Not so much. I think you'll be alright. It's not so much getting it tight, but making sure the top and the bottom are both tight and more importantly level with the inboard section of the wing. If you focus too much on the top, the bottom will be out of whack, either being slightly too high or not tight.
Vic, unfortunately doing it partially folded could be rather difficult, and I think could compromise the strength pretty badly. Glad your parts came in, looking forward to seeing how you tackle it!
