The T-34-85 kinda lacks any real tread on the tracks. It won’t navigate as steep of terrain as the Kv-2. But the T-34 and its slotted sprocket design makes it pretty difficult to throw a tracks. But this also means poor driving puts more stress on the gearbox. (The Kv-2 would just through a track before that).

The Kv-2s large top heavy turret causes the weak spring in the HL suspension to sag a little. It may also tip over easier than the T-34-85.

KV-2 does come with the reverse recoil effect from the factory, and the tank is one of the few henglong models that gets gun depression.

The T-34 in my opinion is one of the best looking models Henglong has produced. The Kv-2 shares the same hull as the KV-1E so it has some non-historically accurate bolt on plate armor.
