You know there is misconception between a rigid bond and a good bond. Rigid bond will more than likely destroy an airframe upon light-moderate impact, whereas a good epoxy bond may snap out and absorb some of the impact.
A model like a BVM Bandit is so well designed that it would even survive on a good CA bond on most formers and bulkheads. The critical thing is how the load is distributed (design dependant).
On a model like a typical FEJ, where contact area is frequenly not even present, the possibility of a good bond using any glue is unlikely. I that case, I'd go for a rigid bond like Hysol, mixed with fibers. I think this is raron's case.
Sorry for the nerd intervention.
