Terrence,
I know for a fact that the main spar is significantly beefier in the 3 series than the 235. Not sure on the outer spars but I would imagine the same is true.
My 235 came with the 320 spars (purchased by previous builder) and I have seen other 235's under construction and they appear to be the same dimensionally  but with more carbon. I would guess in the neighborhood of 25-30% more material. That being said, I would have had no issues about using the original spars if that is what I ended up with. I do not believe you could ever break the thing unless you hit something with it.
These wings are ridiculously strong.

Scott,

Well,let me ask this:  what are the differences between the structure of the 200's wings and that of the 300s.  Mainly things like the wing spars caps, and the landing gear support structure in the wing.  Ws that changed? 

 

Thanks,  Terrence
