The best fit we can make does not have perfect full area contact. A 1/8" square balsa (0.125" x 0.125") will have on one side a gap of 0.0022" if only one (1) degree out of perfect angle. That gap has to be filled with cured glue, not with air.
A crashed landing will survive much better if glued with anything else besides CA because only the covering is holding the airframe together in reality.
You wrote "anything else" _ _ _ this anything else has to be good satisfactory glue for the application.
I never wrote that only the covering is holding the airframe together in reality. I wrote that I read that from someone who wrote it. There might have been some exageration in that writing.
Personally I much prefer to use some brand of wood glue that has a good proportion of solids left after curing, that is not creating any nasty human reaction (vapor inhalation) that allows time for positioning pieces and result I believe in much stronger joints particularlly when filleted properly.
Thank you for that informative information Zor I will use this to my advantage on my next build..

Bob,
You will soon see the gluing of the Kadet Senior that I am beginning to build the wings.
