One on the left is a GF-01 chassis, the one on the right is WR-02...
Interesting comparison, well done!
Indeed - a great comparison; is the track to same? Both look very similar yet I though the suspension arms on the GF-01 were longer.
Nice pair! Really not much in it!
There's not much in it at all, the chassis width is almost the same, the suspension arms are nearly identical, aside from the front because of the need for a drive shaft but it's no wider.
A bit of trimming to Willie's foot and the central tab under the body it sit's at the correct height (This could also be achieved by trimming the battery cover)
