Our Traxxas X-Maxx has gotten some good use. The internet thought it was slow at a impressive 35mph, so Traxxas released a conversion for those with the 6s version. The new conversion gives you an upgrade ESC, drive line and some other components to handle the power upgrade. For just $299 (plus 175 core charge) you can step up the new version of this amazing truck. Our review of the 8s conversion shows you the new power and the awesome bashing you can do with it.
