I don't have the electric version of the Long-EZ that they call the "Voyager", but I do have the yellow version of the glow powered model. Here is a link to an online CG calculator that I used to verify the given CG of the one I have, which turned out to be within just a few millimeters of the same spot.

I'd suggest you keep searching for the factory specification and verify it like I did with the calculator. Good Luck!
