Just a point about Woodys comments. People have experienced some difficulties with the DX6i/BR6000 set up because it can lose its bind on occassions (disconnects from the tx). The DX6i does work very well with the AR500. As I understand, the BR6000 works well with the DX7.

By the way you can get the BECs and spped controller from http://www.technobots.co.uk
www.technobots.co.uk and the Spektrum from any good model shop.
