It's really simple, fly the ARFs as received from the factory or spend an hour with some med. CA or a little bit of epoxy making sure CRITICAL joints have a good bond. I just witnessed a very high end ARF landing hard and the entire firewall, motor cage and cowl FALL right off. We looked it over and found maybe 25 percent of the glue joints actually had wood to wood contact. The rest of the THIN CA simply wicked away leaving air to "hold" the parts together. We glued it back together with med. CA at the field and it flew 15 minutes later. It has to do with using thin CA to glue plywood, that is just not the stuff to use. Really, it only takes a little bit of time to do the re-glue. If you want to just fly it out of the box without extra gluing that's fine. We're not talking about adding much weight here! Maybe 1/4 oz. which my 4.5 lb models won't even sneeze at. As far as the C/F mat it's very thin but I feel it adds some strength to the root rib. May not be doing anything for me really. Peace of mind?????
