Default RE: Building the Yak 54 - 79"

Hey 1fish, keep up the good work, we want to see this done before it gets warm. One note on the wing build: you mention turning over the rib angle guide? This is not correct actually. Remember even though you are building both wings over the same plan (this is possible because the wings are quad tapered and completely symetrical) the ribs will ALWAYS tilt toward the tip ribs. If you think about it it makes sense because the tip rib is smaller than the root rib. So given a wing laid flat on your board, the ribs lean toward the tip. When the wing panels are put flat against the fuselage side, the ribs are all vertical and the tip rib would be suspended off the table.

Yes but if you are building one upside down, (the right panel) and one right side up (the left one) you need to angle the tops of the left wing and inversly the bottoms (relative to the plans, the top when you turn the wing over) of the right wing. Correct?
