Last night I looked at the leading edge of the wing. The original had a perforated sub-leading edge, that's why the tabs are there. The kit does not include this, although it does for the TE. I thought about cutting the tabs off, but then I would have just a butt edge from the sheeting to the LE. Today I'm going to get some 3/32 x 1/4 strip and put them above and below the tabs. That way, the sheeting has a "landing" to glue to, and the LE will have a more solid gluing surface, too.

CA sure makes building a lot more fun. This construction with Ambroid would have been a nightmare of pins, jigs, and weights.
