Some odd prop behaviour where it can sometimes spin backwards depending on your airspeed when you cut the engine. Ground handling isn’t that great, and in the release version at least there was no rudder authority near centre, though I think a later update has resolved that one.
I’m sure there were a few other things, the worst of which I think has been resolved, where the the plane would try to roll opposite to the rudder, and even now in crosswind landings, where you are aileron into wind, and applying opposite rudder it feels like you actually need to do the opposite. I think the wing dihedral was increased, but maybe it needs a little more? Neither the 10 or 14 feel like that.
