Hi, Check the set screw on the wheel that doesn't roll forward. It may be slipping on the drive shaft on the gear box. Mine was doing that when I got the tank. Hope this helps.

Might be one of the motor speed controllers has failed. Not really a repairable item, but if it is an RX18 board (it be in a black plastic box with a silver Heng Long sticker on the top) a replacement board isn't too expensive to replace.

hi i bought a heng long tiger recently the latest version i bought it faulty with the rx18 board ,this had exactly the same issue worked perfect in reverse but only one motor would move forward,took it apart and it was a faulty rx18 board a fraction of it had got hot and melted one of the motor connecters,
had it at a brgain price put in a new rx18 board in it and works perfect

Thanks Jack, Tankbear and n1ghtpony for the prompt replies. Will check the drive shaft on the gear box first before replacing a new rx18 board.
