We study supersymmetric AdS
flux vacua of massive type-IIA supergravity on anisotropic G2 orientifolds. Depending on the value of the 
flux the seven-dimensional compact space can either have six small and one large dimension such that the “external” space is scale-separated and effectively four-dimensional, or all seven compact dimensions small and parametrically scale-separated from the three external ones. Within this setup we also discuss the Distance Conjecture (including appropriate D4-branes), and highlight that such vacua provide a non-trivial example of the so-called strong Spin-2 Conjecture.
