I build my depron planes with foam safe CA glue, accelerator, and 5 min epoxy. Epoxy for the main wing to fuse, and fin to wing. Everything else is CA. IF your CA is fresh, you do not need accelerator. If you like things in a hurry, spray a little bit of the accelerator on your finger and rub the surface that is to be glued. Put CA on the other and press together. Instant bond. ( do not use too much accelerator as it will melt the foam.) Using this method it takes about 1 hour to cut out out, about two hours to frame up. 1 hour to mount all radio stuff and you are flying. Painting is another story. You can take as long as you want. My seccond arrow took about 18 hours altogether( two days). I used regular packing tape for the hinges. Check this constuction thred out for some pictures.http://www.rcgroups.com/forums/showthread.php?t=302411
