RE: *** Ultra Sport Brotherhood ***
Alex, If you have another kit, then you have all you need to built you the peices for another wing without using that second kits parts. Just pull 1 of each rib out & make 2 of each of them out of bulk balsa planks. As for the notched leading & trailing edge, there not too hard to make. Or just buy those pre-shaped leading edges from a hobby shop & the trailing edge should be easy considering how much cutting, carving, & sanding these things take. Plywood braces & stuff are also easy to make & shape as needed. I would just try to keep the wing parts for your other kit available for that kit when that time comes. Sorry to hear of the loss, but all these do come with an experation date encoded within. We just don't know when that is. Good luck, Bill
