Welcome to the board. You will have trouble and we will help you

The great thing about Heng long is the fact you can buy parts, and this is what elevates them out of the toy box. When they break you don't have to throw them away. You can rebuild them , better than stock. In a nutshell that is why they are still around.

If I were you I would wait for the Panther that is coming out in a few weeks. That should be a pretty sweet tank. If you want to buy something right away a PZ III or Stug are great because of all the metal upgrades available for them.
