Hello i am new here. I have just got a HL Tank 1/24 T-90.

When i tried it it wouldn't run forward, When i press forward only the wheels on the right side(seen from front) move and the tank just spins around in circles to the right.

It runs perfect backward and can turn without problems. But when i drive forward it only goes around in circles.

I opened it up and went over it checking everything but i can't seem to find out what is wrong.

Can anyone help me or does anyone have any ideas on what is causing this ?

Can it be the controller/sender ?

Any help here would be nice

Thanks[]
