I am almost finished with covering Bad Axe. Here I am sticking on the tissue strip stiffeners I use on just about every non scale plane I build. Particularly if the design is a little floppy, like most embryo wings. tomorrow, I will apply a set of the strips that go in the opposite direction in each rib bay. Than I will pin down the wing with any warps I want set, and shrink the strips. Then cover in the usual way. It stiffens the wing by a very large factor, and makes the wing much less likely to develop unwanted warps with a tiny weight gain. Too little to fret about.
Try this, you will like it.

OK, this just might be 'tip of the year!'   (roll it into next year)

http://scienceguyorg.blogspot.com/2017/03/bad-axe-embryo-thermals-do-not-care.html  Is my build report on the Bad Axe, I think too light of longerons were used causing me trouble with covering the fuselage. This is wood you provide, not in the kit.

Still a good looking model and nicely designed...I used to make that mistake in choosing too light a wood for longerons so i started to look for rock hard 1/16" sheet
and strip it...the only problem with that is the ability to place the razor blade at the right angle...I know this is against common practice but soft 3/32" square in place of 1/16" squares works out pretty well with a slight weight gain but at around 20 grams you can still use 4 x 1/8" braided with a carved 8" prop...

Using 3/32" might be worth a try if I build another one.
