Default RE: Building a built-up pattern stab and wing

Thanks Jeff.

No SFG's, I was thinking the wing kit would be a direct replacement for an existing wing. The last rib has holes for blind nuts that should line-up with the holes/screws for the tips from CA Models. Here’s the plan for the PassPort/Visa wing.

Anthony we've tried several plotters and all have the same issues, I think it could be the plans are 84" long and the distortion may be within the plotters tolerances.

The doublers will actually make contact with the skin after the glue for the doubler is set, I have a picture in the next group that shows the glue needs to be ground down flush with the ribs. I could have extended them to the shear webbing but 1) so far there has not been a failure that I know of in this area, 2) in foam wings there is usually less structure at the end of the tube than the built-up wings have so I did not think there would be a need, 3) this makes construction easier when installing the socket - some flexibility in make the rib holes larger if needed to get the exact dihedral and placement of the socket.
