Weskel,
I'm sure Crazyherb will chime in with his expertise, but he has shared this information with me previously as I have hounded him numerous times asking for his assistance when building my Giant Delta and He has always come through. Try the c/g calculator at this site:

I think it is 18%-20% M.A.C. that we want with these Deltas
Crazyherb and Everyone,
It sure would be neat to incorporate a plug in wing scheme to this design. I know that it's not too difficult to add aluminum wing tubes and phenolic tubes to our balsa wings as we build them to make plug in wings, but how would one make plug-in wings for a delta wing of this size. I have been trying to come up with some ideas, but none of them are setting off sparks in my head. Here is a couple of ideas that maybe some of you can work with or maybe they will spark a different idea in your head.
1. Wooden dowel sliding into arrow shafts. Would the arrow shafts be stationary in the main/middle wing and the outer wings have the wooden dowel glued into them? How to make so the outer wings don't fly off during flight?
2. Phenolic wing tubes with aluminum tubes going into them. Maybe similar to above or more like a standard wing?
3. Aluminum "C" channel. You can get this at Home Depot/Lowes. I haven't visioned up an idea with this material yet, but everytime I look at this piece that I have here from my SPAD days I can't help but think that it's doable somehow.
4. 1/8" by 1" by 48" aluminum slapped on the bottom and top of the wing with bolts going vertically through the wing every 8 inches. The bolts could go through wooden dowel inserted vertically in the wing so as to prevent crushing when the bolts are tightened.
5. Same as #4 but with wood instead of the aluminum. The wood would have to be a thicker dimension though to get the same strength. Maybe the wing could be routed so that the wood would sit flush with the top and bottom of the wing when all bolted down. There would have to be two, maybe three of these "sandwiches" on the wing in order for it to work. OR.....maybe just one, with a couple of dowels going into the wing and fuselage/midlde wing to keep the whole wing at one incidence. You wouldn't want the two outer panels to shift like giant full flying elevators!! ha, ha.
Well, that's all I can think of right now. Someone take one of these ideas and wring it out, twist it, work it, come up with something we can use to make these Giant Delta's have removable wings. It would help out greatly with storing them and hauling them. I am fine with hauling my Giant Delta in my pickup, it mostly my H20 Delta that I need removable wings for. But, if we could come up with a solution for removable wings on these Delta's, I could bring more than one to the field!! Ha, ha.
