In 45 years of building scratch, kits, and ARFs, I have never had a plane fall apart in the air, under any circumstances. As they say, different stroke for different folks. I'll stick with what I have been doing, but that is not to say that other methods would work as well. On ARFs, I concentrate on the firewall, wing mounting structure, and landing gear mounts, with a little time spent on overall construction.
Also, no glue will ''soak into'' already glued joints. You are looking for joints with little or no glue, keeping the added glue to a minimum. CA is brittle and makes poor fillets.
Agree for the most part.
Re: ARF glue joints, many times these have joints, especially in the plywood fuselage structure, where glue is applied to one side of a joint, leaving the other side only partly glued. Adding CA to these joints does complete the joint process. Also, thin CA can wick quite nicely into joints through the surface pores of the wood, especially where the all to common ARF glue (I don't know what it really is) just sort of sits on top of the wood. I can't think of any other kind of glue that can wick into existing joints like CA can.
