Hey,
I like the idea of building with coroplast, but now I have a question. I found the Wonda plans, and that one turns my key. Looks like a good first coroplast plane, since all the rest of mine have been balsa or Depron. The plans say to run the internal channels (grain) from leading edge to trailing edge of the wings. Seems like the wing would be stronger, if the grain ran from root to tip. Am I missing something here?
