Ultra Sport builders, I need your opinions
I need some help here...
I will start covering the wing this weekend and after reflecting on the building of the wing before I start covering, I started thinking about the belly section of the wing.
The instructions show this section using crossed grain balsa blocks. I only did two pieces like that (LE and TE) while I switched the grain direction (straight) in the center section of the belly, see pictures.
I got thining how this cross grain blocks add strength to the whole wing structure or are just for filling in the space. In other words, is the fiberglass enough re-inforcement to hold stress in the wing on this model?
Thus, If cross grain will actually add strength, I will redo the center section of the wing's bottom.

Don't worry about it...like these guys said, the fiberglass tape is the real reinforcement.
In fact, on a lot of models the belly pans are simply ABS plastic.

WOW,
This is what I love about RCU. Lots of good people willing to help out and share experiences.
Yes, I did fiberglass the wing per instructions. So, I will be okay. Now, I can continue with my plans of covering the wing and be closer to maiden flight.
Thanks a buch guys.
