Thanks Uncle Tony.
As for my turnbuckles, I use 0.5 mm brass tubing and Maxima Chameleon 2lb test monofilament. I picked up this technique from Des' website. The illustration I made below shows two different methods of attaching the turnbuckles to the wing, or fuselage for that matter.
Up until my Dr.I build, I was attaching my turnbuckles as per the illustration on the right side, using a long and short piece of tubing and gluing the tail of the eyelet in the wing. On my Dr.I, I used the technique as illustrated on the left side. Albatros1234 suggested it to me and it offers two advantages.
In the first place, it eliminates the short piece of tubing. Secondly, by connecting to an eyelet, the turnbuckle is free to rotate to line up perfectly with the rigging, as opposed to having to bend the tail of the eyelet to make the turnbuckle line up. Sometimes I had difficulty getting the turnbuckle to line up perfectly as I didn't get the eyelet bent at the correct angle. Albatros1234's method is virtually fool proof.
I can say that as it worked for me!
Cheers,
