Assymbly Wing Insertion Order Question

I doubt it Steve. Once the drag pins are located the wing is stable.

Agreed 100%. Now, for all of us that fly gliders that have pins
sticking out of the spar stub(s) (Glasflugel, Schempp-Hirth, Applebay,
DG?), how many of you have not once accidentally pushed one wing out
with the other while trying to assemble? Not me. That is how I found
out. Put the more stable wing in first and take it off last is my
motto.

As for Schempp Hirth and those side hinged canopies... The L-33
Blanik is that way, too. But with it, you have to put the left wing
on first if you want to use the retainer pin to hold the first wing in
when yo put the second wing on. And if the fuselage is not rolled
back clear of the trailer, the pilot gets to put the right wing on,
run around the front of the trailer, and over to the left side. Then,
open the canopy and use the assembly tool to pull the wing the rest of
the way home. At least, that is how it works with the one at our
field.

The foolproof answer is this. If you hang toilet paper
so that it pulls down in front, put the left wing in
first; if you hang it so that it pulls down behind,
put the right wing in first -- or vice versa. Have
any of you queried the manufacturer? Some toilet paper
hangers have done so!
