Why not use the Plastic?
 

Everyone who has owned an Associated B4 will probably of heard/know that you use the plastic chassis not the graphite one.

So why does the X6/X6 Squared use a graphite chassis? Can you not use the plastic chassis that comes on the X60 if your thinking of upgrading to the Squared set-up?

The X60 chassis is approx an inch longer than the X6 Squared, so not reccomended to use that.

After extensive testing we have found the buggy far more consistent with the graphite chassis, but the truck seemed to prefer the extra flex of the plastic one.

We are looking at the possability of a plastic chassis as a tuning part for the Squared but this will only be released if we feel it is a worthwhile option to have once we have fully tested it at several tracks all around the globe.
