Gustavo, the position of the c.g. at the wing root for a flying wing with a swept back wing will look odd, when compared with normal aircraft. Realize the manufacturer wants your airplane to fly well.
He won't mislead you.
The 10-5/8" distance from the nose to the c.g. is probably correct.. I have to say "probably" because I don't know the actual shape of the aircraft.
If you could measure the amount of sweepback in inches, then a more definite answer would be possible.

Gustavo, I went to the link you supplied:
http://www.proseth.com/eagle/mega/hot.htm
and downloaded this excellent image of the plane, and using normal c.g. geometry came up with the result in the attached image..
A 15% c.g. is quite reasonable for this type of plane..
.
But I believe this is an advanced airplane, probably a handfull for a beginner.
It should fly well though..
