Funny, that DR1 I was playing with was blown up to 1/4 scale from a Guillows kit! I think it had some problems in design. No biggie, it was given to me, then I in turn gave it away. I am currently getting ready to buld a new DR1 as I lost mine due to radio failure a couple of years ago. I am going to make it more scale, but I will leave the airfoil alone as it will be a throw around model, and I like the way they fly stock.
I think you can cheat a little on your wing, and there are certainly ways to have the wires made to stay in place for transport. Things like having the wings slide on tubes to a center section over the fuselage, leaving most of the rigging in place. Also, the stretchy necklace material you can get from the crafts store make good rigging as well. Not functional, but easy to attach and detach for the look.
