It looks like the same nylon tracks and sprockets they are using on the Hooben ZTZ-99A I have. I haven't run my ZTZ outside yet so I can't comment on the durability, but the gearboxes in the ZTZ are really noisy. If they are the same tracks they are narrower than the HL and Tamiya tracks. Seeing that the ZTZ has track skirts like this one, the HL and Tamiya tracks won't fit it as they won't fit under the skirts of my ZTZ.
