Yeah you can get them here. They are called the Tamiya M-03M. I have the Tamiya M-03 with the Mini Cooper S shell which is the short wheel base version. The M-03M is the medium wheel base and the M-03L is the long wheel base. Their little rockets with upgraded motors and they are really cheap. I run a 17 turn double and Electronic Speed Controller in mine with Tamiya FF-02 Front Shocks. Their only let down is the stock tyres. Pick up a set of HPI RS4 Mini tyres and your all set. Here is one thats available on Ebay.

The best way to get an RC Swift is to buy the Mini Cooper S version and get one of these Swift Shells.
http://www.abchobby.com/abcframe/infram ... swift.html It's a better looking shell in my opinion and it comes with light buckets so you can add LED's for head lights and tail lights. LED lighting harnesses can also be bought from the same company.
