Just noticed from tracstarr's post that he is gluing the Oratex to every cross and angle tube that the fabric touches. With PolyFiber in most cases you only glue the fabric around the edges of each piece (on the wings you do glue each rib). All that gluing seems unnecessary to me; it also seems that it would be very difficult to get even and consistent fabric tension over the whole panel. Is this really what Oratex requires?
