With several swept wing planes, I have found the geometric calcs to place the CG aft of ideal, or flyable in some cases, for that matter. For whatever reasons unknown, it would seem the inner wing area has more effect on stability and determines the CG than the outer area. A chuck glider using the same wing as the finished plane produced the same results once for me. With the added weight, the finished plane wanted a CG much further forward. In summary, while rearward sweep moves the CG rearward, it is not as much as would be expected.

I like that site. It even gives the stall speed.
Is it pretty accurate w/o swept wings?

The c/g calc gives a pretty good starting spot. I usually set up my plane accouding to that to start with. I usually leave the prop off and run around the yard making vroom- vroom noises and tossing the plane around for a few glides. By moveing the battery around and looking at the glide path a man can get a real good idea of how many pieces the plane will break into on the test crash.
