It seems every time I use straight push with manual stop, when I do stop it, the wing walker walks way past the rear of the plane. I do not get the set park brake message until he's back there, then I have to wait for him to come all the way back up before I can depart.
Also, maybe unrelated (or maybe it is) but, it also seems when letting it run it's course, wether it's all the way to the limit, or left or right (not stopping manual), the walker seems to stop walking too soon, and the tug pushes me about 50 - 75 yards away from him.
This is p3dv4 (4.2) with the iFly 737. Haven't tried other aircraft yet (because there aren't any, lol)
