From what I understand, when CA cooks off it does not lose weight. CA is not a water based glue, and it does not work by evaporation. with 2oz CA in one wing panel alone, that is 4oz for the wings, and another 2 to 4oz for the fuselage. Not only is the weight racking up, but also the expense at 3 to 4 dollars an ounce. That would also mean even on a glow plane that you would have to go with the largest engine just to get off the ground. If weight wasn't such an issue even with glow/gasoline models, they would be designed with pine, oak and other woods that are much cheaper to obtain and sturdier than balsa and lite-ply,

Accelerator is used to speed up the curing process of CA. a side affect is that it gets harder, and boils up leaving a nasty looking mess. The only time I usually use accelerator is when joining balsa to plywood, or to plastics. Thin CA alone when joining to plywood can take a few minutes. Also if you get medium or thick CA on your skin, don't use accelerator. It will get hot enough to blister.
