Try checking the DnR Military Jeep. It is a crapon, but the aiming works nicely.
I do believe the only issue with it is a missing .dsq or .dts that crashes clients when spawned. Had the same issue with one of my playertypes.
Srsly.
You did not get what i am trying to do here.
I am trying to make it aim on itself, not by a player.
Player can aim it quite well actually. ;P
