Gulp SR Re-build

This really qualifies as a "Re-build" but with the time I spent it felt more like a full build, (note to myself.....never again)
I started with an older SR that I picked up second, no make that third or forth hand. Regardless, I got it from Adrian "codezilla" and it was a great deal, pretty much RTF. First thing I noticed when I picked it up is it was completely covered in Solar-tex and was, well I think the best description is "baggy". I did my best to tighten it up but it still had a lot of sags in the covering and the elevons had a quarter inch play up & down , not good on a plank.

Anyhow, after a few weeks of trying to make the best of it I gave in and started ripping the cover off. When I was done, I could hardly believe my eyes, 7.5 ounces in covering and a fuse that was slightly beyond repair.

Got together with Steve Drake and he set me up with a new fuse / tail and elevons. I started by filling the old servo pockets with EPP (they were under the fuse and drove torque rods). I then put in new servo pockets and potted the servos. Then I fixed the outboard end of the elevon. Added some uni in an attempt to strengthen, but doubt it did much. Also added uni to the drag spar.
Did some plywood inserts at the control horn attachment points and at the ends of the elevons.
