  We report on a first study towards the use of stabilised Wilson fermions in
heavy flavour physics. In particular, we are interested in fixing the charm
quark mass via various physical observables and to inspect cut-off effects
arising from different choices. This is done on large-volume OpenLat ensembles
with periodic boundary conditions. Two different ways of fixing the charm quark
mass are explored, namely using the mass of the $D$- and $\eta_{\rm c}$-meson
as physical inputs. We furthermore give an update on our determination of the
non-singlet axial current improvement coefficient $c_{\rm A}$.
