While on a search for other information today, I was reading up on super glue and was surprised to learn that nitromethane is a good solvent for dried CA glue.

Perhaps something you want to allow for when gluing in firewalls, motor mounts, etc, where raw nitro will come in contact with the bond line.

I sometimes use slow CA in the nose to do basic assembly, but the nose is always coated in epoxy and usually light fiberglass.

Back in the day of the dark side, I built a plane competely with the appropiate CA glues for the different portions of construction.  I was watching the video of how to do it during the construction.  When I sold the plane several years later the only thing needed was tightening of the moneykote.  DOC Holliday

Is that video still available?

Interesting, I butt glue with CA and nothing breaks (I never had Duco, Ambroid or Sigment pull loose on any joint either and that spans about 50 yrs). Pulling out of a CL wingover is mild in comparison to worst case RC so something tells me your glue was bad. I don't know what I do differently than anyone else with CA except for possibly using it heavily and always using a fresh batch. CA definitely has a short shelf life (longer if kept in the fridge) and there is major strength differences between brands. I don't use the cheap stuff. Were you using thick CA? My limited experience with thick showed it didn't penetrate or hold as well as thin...there is no thick CA on my bench anymore. If gap filling is needed I go to Duco/Sigment or worst case epoxy.

One of my 40 size rc full fuse ships (mid star 40 with 50 Fox) took a dive and broke the nose off in front of the wing. I joined the ragged edge back and glued with thin CA. While not a clean butt, it held fine and crashed hard again months later...this time it broke the nose off in another place and the CA joint didn't fail. That was a major turning point for me away from epoxy.
