I had to think for a while to decide where to put this, but since it is more a design question I thought I'd put it here.
I am working on the attachments for the wing spars to their corresponding fuselage ribs. I have drawn the 2mm (0.080") spar web to attach to the rib of the same thickness, via 2x 1mm (0.040") thick joiners riveted to each piece. The diagram shows only the wing side (and some of the main retracts, which I am in the process of at moving)
My questions is, will this be sufficient to support the wing and carry the plane on the main gear?
My reckoning is it will be, but I never discount the value of a second (or third etc.) opinion.
Next thing is to work on supports for the main gearin the wing. I am investigating this possibility to minimise CG shift, make the retracting mechanism easier to manage and give it a more stable base for taxiing.
