They say that you can weaken CA joints by freezing them.

Of course, you may weaken the plastic parts that way, too.

If the plane is unusable in its glued state, you may as
well go ahead and experiment with the cold treatment.
Worst case, you break the pieces entirely and have to
buy spare parts.  But if you don't break the joint,
you have to buy spare parts.  

What have you got to lose?

I don't know if a commercial product like Bob Smith's Un-Cure will
damage plastic or not. It does say it will remove some paint on the
bottle instructions. The guys I know are using low temp glue guns to
build and repair their indoor foamies. It doesn't take much to make a
joint. A lot cheaper than gold CA too. Don't use a high temp glue/gun.

Debonders for CA will also affect most plastics.  Your option is usuall
only cutting the parts with a razor blade or razor saw and then bondin
them back together

Cant be done except by careful grinding.

All CA solvents attack nearly all plastics.
