Yes. Reset timmer, slow down to zero speed and turn hover mode on. There is 2 modes of altitude hold (switch near AP channel buttons): barometric and radar. Radar mode is good for terrain following, but bad for hovering over a place, which isn't parallel to horizon. Ka-50 will be unsteady, if you try to hover over something like steep slope of mountain with radar altitude mode on, because little drift will induce change in altitude (from ground) and Ka-50 will try to compensate and sometimes to overcompensate...
