Its probably in this thread but I will repeat what I said regarding the shear webs or I-beams..

I initially was concerened about the grain orientation in the instructions. I called Jeff and he assured me that the loads placed on a fun fly wont be enough to matter..

My webs dont run the full lenght of the bay because I used the supplied 3" wood for the webs. The bays are wider than that. I butted them up against the inner rib, and the top and bottom spars..

The design has no spars than cross the wing centerline but that doesnt matter because the sheeting goes all the way across on the top and bottom.

This wing will not fold if the plane is flown with the recommended engines and flown within its envelope. (which is pretty wide)
