Woohoo, we finally made it. We're actually getting to the steps where we get to join the wing halves. Yippee, yahoo.

With the W1 ribs set we need to cut off the excess leading edge, trailing edge, main spar, and rear spar. Just like when we cut off the excess at the wing tips we want to cut close, but not too close (picture #1 & #2). Leave a little excess and sand it down to where we want it to be. Carefully sand down everything flush with W1 (picture #3 & #4), be careful as you don't want to sand into W1 (picture #5). One quick step to do before we move on is to cut out for the aileron servo. The cutout is already scored, use a hobby knife to continue cutting down to the sheeting (picture #6). Once you have it cut down remove the material in the cutout area (picture #7).

Now we need to cut out the W1 rib in order to for the dihedral brace to be inserted. This is another area where we need to take our time and do it correctly. It would be easy to just take your knife and cut across the are to be remove, but this will usually result in the wood splintering or breaking and that's definitely not good. I prefer to use a straight edge to mark a line where we will cut (once again this falls into the “measure twice, cut once” area), by marking the line (picture #8) we know exactly where to cut and there is less chance of making a mistake. With the line marked use a razor saw and carefully cut the wood (picture #9), you want to avoid the wood splintering so take your time and cut slowly. Picture #10 shows the cutouts completed. Now we need to get the dihedral braces ready for joining the wing halves. Here is another place where we need to make an accurate measurement. Place the dihedral braces on the template in the manual to mark the centerline of the brace.
