First of all all of the above are good to certain aplications. I prefer CA on most balsa because of the speed and it will last as long as any glue. I use wood glue on large scale and major jobs for the cost factor and it does clean up nice. It also seems to work better when laminating 2 pieces together. (they hold better) with wood glue heat has no factor in strenth of structure and I've seen planes 20 years old that are as strong as the day they were built. Epoxy is my choice for tail feathers, firewalls, landing gear and wing blocks, or any other high strenth aplication. I prefer loner time CA such as 30 minute, the faster it sets the more brittle it becomes and with a plane I prefer a little streatch to it. One thing with epoxy that most people ignore is the heat factor that effects it. Once epoxy is heated up it will release or become weak, if you recover a plane it may cause structure problems in the future so be carefull. If recovering and not sure of strenth in joint you can simply heat up epoxy area and with a little work it will release, then clean up same way and rejoin. Hope this helps and this is my view and it may be wrong but it's worked for me over 16 years.
