I have used Wellbond, Elmers and Titebond II with equal success on all of the woods.  In cases where extra strength is necessary like firewalls, I use epoxy.  I use epoxy on wing halves, tail feathers and some structual repairs like doublers.

Right now one can get 4 fluid ounces of Elmers at Walmart for $0.40 in the school supplies section.  Works well on wood especially balsa.

I only use CA in non stress locations, fine cracks and the like when repair wing surfaces.  It is okay but just not as shock resistant as Aliphalatic glues like Elmers or Titebonds.  Wellbond fits in that category.
