just FYI, i've received some new items from X-Power including
Ceramic Ball Bearings,
Ceramic Diff Balls and
Slick Tires. i've tried both bearings and diff balls, they are very much "tuner's" optional parts. i say that because you won't see a huge difference in performance, but they're just an improvement on existing items. the tires are thicker and should last longer. due to import restrictions, i've only got 3 of the
Travel Charger so pick that up quickly if its on your 'wanted' list. currently X-Power products are available only
