if a blinker lies on a seam (like the aft ends of the nacelles or the blinker under the secondary. hull) that will be glued with styrene cement I will drill a hole thru a short piece of small diameter styrene rod and feed the fiber thru the hole. Then I take a small round file and make a half circle in each half of the kit part opposite each other where the tube will be glued in. That way the styrene cement is glued to the styrene tube and not the fiber. A small drop of CA is enough to hold the fiber in place inside the tube: 5 minute epoxy works too.Really great build! I'm working on the same model at the moment. I see we're both using fiber optics for the blinkers. I'm wondering how you're gluing seams together like the ones around the nacelles without melting the fibers. I've tried a lot of things and have yet to be able to use styrene glue with out the fiber breaking. I've been reduced to using 2 part 10min epoxy on those areas which I find has a little give and definitely doesn't leave a completely gapless bond.
