problem with Virus

[zipperone]

Hi,

I own a Ansmann Virus 1/8 buggy. Its got about 8 tanks on it and was doing fine until recently.

The buggy starts fine but does not move when the clutch engages.

The front and the rear wheels spin in the opposite directions when I lift the buggy off the ground but obviously no movement when i put the buggy back on the ground

I rebuilt the centre diff and added 3K oil , still the same.

What am I doing wrong?

Please help

Thanks

You put one of your diffs in backwards or upside down.
