Hi!
I'm new to the Nitro RC scene, so I don't know what to do. The back wheels on my 4WD Tamiya TGS are not working- is this because they are rubbing, or more intricate than that?
I can see that the back wheels are slightly rubbing on the back screws of the Chassis, but I don't know if this is the main reason. There is a small squeaking sound, and instead of drifting, which it should, it has understeer. Please help!
Thanks

Remove all the wheels and turn the front wheels to see if the rear wheels turn. If they dont check your rear gearbox. This is a start.

As i say, im new to this hobby, so could you give me a clue of how to fix it?

I suggest read the manual, this is the only way you will learn. You will have to open the car up.
