Thanks,

I am wondering if perhaps my thin CA is getting useless, it really, really does not seem to want to grip things, except my fingers, I tried to CA sheeting to the LE on one side, and it would just not hold, even with tight contact. Interesting. I had to wood glue and t-pin the whole sheet to the LE.

Also, with no rib jig tabs on the upper surface, when I sheet the bottom, I am woried about inducing some sort of warp, think that is a valid concern?

Wing seems incredibly light and well, weak. I cannot imagine it taking all the stress induced 3d stuff, I mean 1/4 inch BALSA main wing spars? Man. Even half of it being doubled to 1/2 by 1/4 seems really weak. And no rear spar, is a good amount of flex there.
