A different twist - Zor referred to "all old timers"
Before ARF's everyone built. The ones that were in a hurry built their models "in a hurry" disregarding attention to details. They also used CA BECAUSE they were in a hurry. As a result the finished product reflected them being "in a hurry". Probably didn't last long.
Today, the fliers that are "in a hurry" buy RTF or ARF products. Those of us that build are NOT "in a hurry" and we pay attention to details whether we're using CA, AR, epoxy, hot glue, or any other adhesive. As a result, pilot error or an occasional radio hit (or other pilot hit) are the reasons that today's kit airplanes fall out of the sky NOT because CA was used.
Hope that that makes sense ... (it did when I typed it

)
After thought - the only airplane component failure that resulted in a lawn sale was my 1st plane - SIGKadet Sr. ARF - the wing collapsed just outside the "main spar doubler". Bob Nelson of SIGsaid that there were "build"problems with the wing and if I'd send it back SIGwould replace the plane. Oops - I field stripped all of the serviceable bits and tossed the rest in the field's dumpster. Arrrggggg - there is a lesson here ...
I referred to "old timers" as the fellows that had to build their model if they wished to fly before ARFs and RTFs were available.
Your second paragraph illustrates exactly the point I was making.
I certainly DIDNOT imply that models fall off of the sky because they were glued with CA.
I only referred to the results of a bad crash.
What you wrote does make sense to me.
No doubt there is a lesson from your Sig Kadet wing folding. However we do not really know the reason for the folding. It may have been poor glueing but it could also have been weak spar material or a covering that did not add strength to the frame.
