Fear not - despite rumors you may or may not have heard, the MT4 is NOT being discontinued.05.29.12LaTuFu in the forums just spoke with a representative of Thunder Tiger USA about rumors that the MT4 has been discontinued, and was told The MT4 isn't going anywhere. He was told that the MT4 is a huge seller right now, and that Thunder Tiger is upgrading the radio system in the RTR kit, so it will be getting a completely new part number. That is why some shops are seeing that they are not able to order the old part number. So don't freak out; the truck will be on shelves soon
