I believe I just came across an error in the manual. I wonder if anyone else has noticed this yet. On page 12-06, Figure 2 it shows connecting the torque tube support bracket to rib W-1010-R. It also shows a flap hinge bracket attaching to that same rib. The rib does have a drill pattern that matches the flap hinge bracket, but on all other drawings there doesn't seem to be any flap hinge brackets attached to that rib. I'm guessing that's an error in the drawing and this rib should not have the flap hinge bracket. Also the wing kit only came with two flap hinge brackets per wing which show attached to ribs W-1011-L & R.
I've sent an email to Van's to confirm if this in fact an error in the manual and will post what I find out.
By the way, the wing kit isn't quite as easy as expected. The wing ribs are the same ones that are used in the RV-10, so they are not drilled to full size. At least the skin holes are drilled full size so still no match drilling required. The manual just indicates to drill all the wing ribs prior to assembly.
