I also know that it IS possible to assmble an ASG-29 with a "miss"
similar to this. I got to help remove a wing, get it right, and put the
pins back in on the grid at a contest. The driver went in the fuselage,
but missed the cup in the fuselage.

The moral of my comment was that just because there are automatic hookups
doesn't mean they will always hook up. I am pretty sure I can get the
wings on my Austria and miss one of its auto hookups. On SH and
Glasflugel stuff, if a control surface is held full travel one way, this
will very likely happen. So, when I am helping my friend with his
Mosquito, I make sure I get the aileron near neutral as we are sliding the
wings home (he has a mid-aileron leading edge dolly that is held in place
with a loop of big bore surgical tubing that can set teh aileron against
the up stop.)

I am also quite aware of how shots are made and assembled for a piece like
that shown on "How it's made." Ever notice how many shots in "The Boy
Who Flew With Condors" have the registration number on the 1-26
backwards? And how many times his hair parts first on the left, then on
the right and back to the left in one flight? Some of us don't have to
worry about combing our hair back and forth during a flight! :-) I
remember discussions about "Why did the towplane break right when the
glider released?" Because the film was flipped around!
