Thanks for the kind words Ed! In mine I used a 7.5mm hollow wound carbon spar. The info from Radical R/C where I got it:

Hollow Rod. 7.5mm (.295") OD x 6.15mm (.243") ID x .803 meter (31.625") Length. These rods are wound (not pull-truded) and represent an exceptional value. Very stiff, very light (17.2g). Perfect for boom's for DLG and other types of pod and boom models.
It's a little stiffer than the 5mm pultruded rod I have in the Peace Drone's wing. It seems plenty strong for my intentions, but I'd definitely run struts if I were going to haul a few pounds in it... lol I'm just looking to drop some parachutes out the back later once the flight testing is all done!
