Your welcome. Yes the Vertex is all 3mm Depron.
Sorry about not posting the C.G.s I wasn't sure where they where going to end up when I drew the plans.
Vertex C.G. is 11" FORWARD of the elevon hinge line. Please play with this position as it is the only C.G. location I have used on it so far. I will play with it as well of course. 
Vertigo C.G. is 5.25" BACK from the root LE. Again, this is a preliminary position and I encourage you to play with it and report back to us.

I built a couple of Vertex's and I have a comment on the CG location. From my tests the CG as it's located on the DXF makes the plane very nose heavy.
 I've built two. One is a 50% plan size glider and one is a 75% plan size with elevons (no rudder). I have not flown the powered one yet, but from glide tests on the unpowered 1/2 size I can say this: CG is 47.5% of the distance from the elevon hinge line to the nose. So slightly less than half way from back to front excluding elevons
