O.k., You are talking swept wing I see. The way I do them, might not be considered conventional but it works. When you do the body wrap take a piece of thread and bend it in half to make a loop. On the one wrap of body material where you want your legs to be, wrap the loop of thread under the body material and insert the rubber leg. When done with one or two wraps pull the thread and rubber back toward you. Now you have swept legs. Of course you have to do this on both sides of the body at the same time, so I guess I should of said two loops of thread(LOL). Hope this works for you.
