Those xbee controllers look sick, since the last update was jan 2013 I assume they wont see the light of day which is a shame.

Higgeh, thats what I was thinking like sticks for steering left trigger for throttle and right trigger to fire a weapon. I have to say I've not used standard transmitters a whole lot but in my head I feel like an xbox controller would be a much more efficient way of controlling a machine.

Interesting link as well I shall have a good look at this.
