I can take a pic. For right now, the spar goes into each wing section, and they then slide into the fuselage recesses an inch or so until fully seated. Then, you insert the 1/4-20 bolt into the wing from inside the fuselage. After you get all the servos and air tank, etc, inside the fuselage, it gets pretty crowded. I find it hard to get to the bolts to work them into the wings. It's possible, however.
