I am not sure if you are asking about Mattorro or Mato tanks.... Mattorro are no longer manufactured and are very rare now. Mato is the new kid on the block, and are in line with Heng Long tanks as well. Heng Long has come a long way from the scale-ish toys they started with - the Pan-Tiger comes to mind. But the newer the model, the closer to accurate scale they are. Mato being new has some issues, but are pretty good- I have one of their Shermans and it is nice (with the exception of the excessively fat cannon). But I gut everything and put in Heng Long RX-18 boards so my tanks are all compatible. I will leave more details on the inner workings to the more experienced members of this forum. But it might help if you explain what you want to do- build a shelf queen, have something to bomb around in the back yard, or compete with others in staged battles.
