Barnsleybot:

it's a thwackbot, it runs a metre long axe, 2 gimpsons, 3.5ah 12v nimh and 2 50 amp boat escs. made from hdpe with an ally treadplate lid. all safety stuff installed (link, powerlight, failsafes). one of the 50 amp escs is stuck in forward, i'll include a spare though. weighs only around 10kg so you could really beef up the armour/components if you want to.

looking for around £100, w/o radio gear. postage would be about £10
