Popis:	In this letter we discuss de Sitter vacua in maximal gauged supergravity in 4 dimensions. We show that, using the newly deformed theories introduced in arxiv:1209.0760, we can obtain de Sitter vacua with arbitrarily flat tachyonic directions in the SO(4,4)c models. Comment: 12 pages, 5 figures. v2 references added
