First the question on shaping the wing tips;
Ya know, I didn't really have a good way of doing that. I found that as a bit of a sticking point too. The plans don't really show it, so I just sort of guessed. The supplied wing tip is made of balsa sheet, laser cut to its rounded shape. It slides into a notch in the main spar, inbetween the TE sandwich construction and on top of the LE dowel. I used epoxy for where it touched the cedar LE dowel, and Titebond 2 everywhere else it touched.
I sanded (used a razor saw for the ruff angel on the dowel) the dowel, spars, and TE to match the taper the wing tip would provide to the covering. I'm not sure if this was the right thing to do with the TE sandwich construction, but its what I did. I rounded the corner of the LE dowel. I hope the pictures help.
Also, I think the forward spars were meant to be cut flush with the last rib. Instead, I added pieces of balsa between the forward spars and the wing tip piece.
This information, along with the photos, are very helpful. Now I have a better idea of how to shape the wing tips. The covering is looking good so far, I see you have yet to put the stars on the main wing. From what I recall, you were going to cover it in white first, then overlay the red design to make the white brighter. However, I see you decided to start with the red first, at least on the main wing. Although a little darker, it's probably an easier method.
Meanwhile, I should be back on track with mine fairly soon. But, I also have yet to finish a Lanier Citabria project.
