Start with 0 on the stab and adjust from there. Since the wing can't be adjusted, just set the stab between -.25 to -.5* relative to the wing and start from there. I met Chuchat, the designer of the Beam and have seen him fly both the older version and the version you have. He flies it pretty well so it should be a ok plane.
