i think radioshack removed xmods website, but you can still buy xmods parts at Atomicmods.com or Xmodsinternational.com
ALL OF THEM.
In a nutshell, yes. They are returning as "Xmods Street"
no, Sorry.
eBay.
u can normally buy them at radioshak
Xmods for video games can be difficult to come by, as they require customization of either physical components of a game system or of the game code itself. Most Xmods can be found by visiting online gamer forums, but these are technically illegal modifications to copyrighted hardware and/or software. Proceed with caution.
Any, Xmods are fun out of the box and can be competitive with a few aftermarket upgrades
You can find them online (they don't sell them in stores anymore). Usually you will find them at ebay.com, xmodsinternational.com, or atomicmods.com
Well I don't have the certain amount but just get a subaru xmod (any color) and paint it yellow. :)
Some of the easiest upgrades are thing such as a 6 cell upgrade, Lithium Ion, and Lithium Polymer. They increase voltage, hence speed. Another is upgrading the motor. A more powerful motor equals faster Xmods. After that, it's free game (i.e. brushless systems and hobbygrade ESC's) eat loads of pie
There is no definite time when RadioShack releases their new Xmods. All there is to do is wait for RadioShack to put them onto the shelves.
