I used CA on the canopy I just did and it worked beautifully. But you have to be super careful to keep the fumes away from anything that will show. I tacked mine along the edge 1 tiny drop at a time, holding the canpoy tightly against the balsa and letting it wick in from the outside, constantly blowing the fumes away. I actually had a little fan setup to keep the air moving fast inside of the canopy. I started out on the extremeties and worked my way closer and closer, 1 tiny drop at a time until I had a drop about every 1/8" all the way around. Then I cut 1/2" wide strips of the ultracote I used and ironed it half on the canopy and half on the hatch to finish the edge.

I actually covered the hatch before I installed the canopy, and then cut a 1/8" strip of the covering away right along the edge where the canopy and hatch meet up all the way around the hatch. Actually, along the very front on top, I only cut away the thickess of the canopy so that bare wood would not show. I did this so that I could glue the hatch directly to the balsa and not the the ultracote. It came out very clean and seems to be there for good. No indications that it will ever come loose.

I know its a big plane, but the same principles apply.

Look here on page 2 of my building thread to see how I started and how it came out.
