I've spent a good couple of hours staring at this thing and looking at some of the photos on this thread. It appears to me that the tube is built into a pair of spars that go out to about the fourth rib though the tube only goes to the third rib. I was not impressed with the glue job for the tube so I got out a long brush and some 30 minute epoxy and now it is firmly attached. If this structure fails either the tube will break or the wood will fail. It looks to me as though it was glue joint failure that caused Big G's crash. What bothers me is that throughout this thread the wings that did fail apparently did so because of the incorrect shear webbing. With that fixed these planes seemed to stay together and I know of at least one pattern flier who simply wore his airplane out with an OS 160. I earlier thought that these kits might be new old stock from 6 or 8 years ago but now I wonder if they aren't recently made and that a few shortcuts might have occurred in the building process. I'm waiting for a remote glow driver to get here and plan to fly this weekend. I'll be keeping a close eye on these wings and if something starts to fail maybe I'll catch it before it becomes catastrophic.
