Hi Crius,
I have had no problem with the tracks on mine. I am in Maine, my property is a couple acres of woods and meadow. So there is a lot of stuff (branches, vines, long grass, etc) to get pulled into the tracks. Nothing has broken, the tank runs great and has never thrown a track. The track is wearing well but remember all the plant material means it is running in a “soft”, though grabby, environment. Likely a more abrasive environment (sand, gravel and rocks) would abrade them more.
I have seen posts showing that the extended track ends sometimes break. Looking at lots of photos of the real thing, that happened in rl too. Also it seems the IDF used to remove every 4th or 5th track link end for some kind of maintenance access. The ends simply provide more ground contact and are not part of the functional structure.
I believe there are metal track sets available but the only review I have read indicated a tendency for them to de-track. At present I have no intention to replace the track it came with; following the principle of “ if it aint broke, dont fix it.
By the way, if you get one, make sure to mount the idler wheels in the correct position. They can be angled up or down. One of the two, down if my memory serves, will cause the inner track ends to catch on the idler support, which would likely break some ends off.
Hope you have a chance to get one, it’s a great model of a great tank.
