Got the tracks in yesterday. I have attached photos of the box and tracks. After looking at them and testing how soft or hard they may be I think in general they will only serve as good static tracks or maybe for just running around as an RC, but not strong enough for RC tank battling. The issue is that they are probably 80% lead which means the steel wire they include to put them together will start to wear them out as it is harder than the tracks. Without attaching them to a running T38 or Hetzer it will be hard to test how quickly the wearing will occur? It will happen though. So that said, buy them at your own risk if planning on using them on a R/C T38 or Hetzer. The detail is really clean and crisp though. So if you plan on building a static T38 or Hetzer I would defiantly buy a set. Cost was $43 delivered to the U.S. from China. It only took 14 days to get here. The tracks in the Photos where there are seven put together are not pinned, but just pressed together.
