  We discuss flux compactifications of IIA string theory on G2 holonomy spaces
with O2/O6-planes to three dimensions and find two classes of solutions: 1)
No-scale Minkowski vacua from NSNS 3-form fluxes and RR 4-form fluxes. 2) By
adding Romans mass we find AdS$_3$ vacua for which the AdS scale can be
decoupled completely from the KK scale while the solution is at tunable weak
coupling and large volume. For the AdS$_3$ vacuum we only have a proper 3D
description (i.e. smeared orientifold description) of the solution like the 4D
analogue of IIA moduli stabilization from fluxes and O6-planes. This 3D
description reveals that moduli with non-compact moduli spaces can be
stabilized at the classical level. For both types of vacua we can have
supersymmetry or not.
