I didn't use a jig on my first build. On the second one I used the carbon wing joiner to make sure ply and balsa were lined up. Kept using the joiner to make sure it was square while I glued formers in place. One deviation from the instructions was that the rear fuselage was taped and not glued at this stage...OK, I did glue it but on both of mine it ended up being slightly banana shaped, so had to be split in order to attach the fuselage bottom before re-gluing.
Mike, Am I missing something or do we, or rather, do I need to enlarge the snake holes in PW4 and PW12 as they are smaller than the 2mm snake? The only reason I ask is that everything else seems to be cut at the right size!
Yes. They need enlarging. I used a 2.5mm drill which is a little too big and I secured them at the former behind the wing with epoxy after finding that CA would not hold them in place....no need to fix them at the former in front of the wing. When you pull the tail in you can stick them with CA or epoxy and the whole lot will be secure
