Take a little extra time and look at this set of pictures closely. This step is pretty important. You'll also want to be very very careful when we start fitting the dihedral braces in each wing half. If the brace doesn't fit don't “force it”. All that will happen from that is that you'll wind up breaking the ribs. There really isn't a lot of explanation that goes in here. We need to make sure the dihedral braces fit into each wing half. If the gap between the rib and the spars is too tight use an emery board or your hobby knife to carefully open it up a little bit. We need to make sure that the braces will go completely into the wing half up to the centerline we drew on on each brace (picture #1). As with everything else we have done here, take you time and make sure that they all fit correctly before moving on. There isn't much to say about making these braces fit, but I can't stress enough how important it is that this step be done correctly. Plain and simple, these braces join the wing halves so we want them to be right.
