Wings,.... Obviously pop all the parts out for the wing, the jig tabs go down and there are only 3 ribs that have long tabs, those face up and are used for support when flipped over. When setting the spars down, look down them before pinnin them down, they most likely will have a crown to them, make sure you put the bows opposite each other, in other words, place bolth so the bow faces in the wing on bolth sides or away from the wing on bolth sides. I set mine so the crown faces away from the wing on bolth sides. Like this ( ) or you can do them like this ) (, but it will promote lifting at the tips, never set them in so they face like this ((/ )), your wing will set like a bananna. You can use CA to glue the ribs, I still use wood glue, so I have time to line everything up, if a rib feels like it's too tight, don't froce it, sand the spar groove till it fits snug but not splitting the rib. If you are going to use wood glue and not CA, you'll have to think around the issue of holding the spars tight, I use masking tape slipped under the spar and pulled snug around the top it's a cheap clamp to tension the spars into the ribs. Finally, make sure they are all square, lined up and all jig tabs are touching the plans tightly. Now when it's all set in place you can chack to see how flat the wing is by putting a straight edge down the trailing and leading edge matching the wings sweep to see if any ribs are too low or high. When happy, walk away and let it setup. Applying the wood glue takes the most time but has the advantage of letting you adjust parts before it's too late. So all in all it took me about 45 minutes to get it all set and lined up, now I have time to sit back for about 1/2 hour and relax, answer some posts and then go to the next step, or I can look ahead and set up the wing sheeting so when I need it, it'll be done, preassembly is the key when using slow cureing adheasives. Keep looking ahead to see what can be done while the glue is drying so you don't find yourself waiting for that to dry down the road before you can put it on the plane.
