CA is by far the best, strongest, quickest and easiest method of building. Use thin CA on balsa to balsa joints and thick on plywood. Use a combination on balsa to ply.

Hold the pieces in place, place a drop about every 1/4" - 1/2" along the joint line, and hold for about 15 seconds. On ply to balsa joints, use thin first and let it soak into the joint, then follow with thick.
