Yes, this Panther still has the stock transmission. I have a 3:1 mato gearbox for it, but I ordered the wrong one and am waiting on the right output shafts to arrive. With the 3:1 gears things will improve greatly. Of course I don't need to tell you that, as I think we both agree it is the single best improvement you can make on a Heng Long tank. Protects your board from being exposed to stalled motors and removes all the jerky movement. Sometime today I will post another video showing my old Panther with the lower gear ratio IMO forget the metal tub and a suspension pieces if you haven't upgraded the transmission to a 3:1 yet. OH ya they also help out on that cheesy heng long recoil, and you get a less pronouced Jerk
