RE: Choices, Choices!
Heavy:
I'd not be so fast to jump on the Leopard 2A6. Why, because of reported problems like the new composite used for the suspension cracking in places. The idler-adjuster is also reported to be poor (like most of the Tamiya's) and there are already replacement parts for a lot of the stock items.
Icy:
Its all a matter of how much dinero you want to dump into it.
Drive it like a hot-rod and the parts will not last all that long. You want a hot-rod thats dirt-cheap, get the new Hen-Long Tiger 1 or Pershing with the Smoke & Sound. The MTG guys say the new S&S units can take more abuse (hot-rodding) than the Tamiya without breaking, and their speed controllers are better (about 8 steps vs the older ones having 3)
Do your research before you buy, and you'll be much happier with the results.
