I've seen more pilot and radio problems crash more planes than any type of glue joint. If you look at crashed planes most of the broke pieces are ofsingle wood partsand not the glue joints. Now if its a weight thing Aliphatic glue is lighter than CA.
That being said I just built an LT-40 over the winter and used slow CA on the main spar <span style="color: #ff6600">and it's rock solid</span>.
I respect your opinion of being "rock solid" but it remains just an opinion ___does it not ?
Weight wise ___I cannot see any advantage of saving on glue.
I built an 10 1/2 lbs model and used less than 4 weight oz of glue and that is with double glueing and making fillets at all glued joints.
