Model IV Folded Wing Attach Point

[t j]

It is in the first picture...the red one. It is under the fabric. You need to cut the fabric out of the tube. It is a 5/16" inside diameter cross tube. You need the lock back braces. One end of each brace attaches to that tube with a long 5/16 bolt and the other end to the lift strut attachment on the wing with a pin.

There is a tube right at the black mark and that was what I thought was the attach point, but I see there are different options out there?
