Ok thanks Garfie, not to concerned about competing with this bot,b it of a back to front build, as doing big as I can for cost , I'll add up the weight once I know all the comoonents, but happy to strip it down at a later date to match a weight class, this one is more a learning curve, in a little bit fortunate I work a t a go kart centre so plenty of spare materials and a chap that will do my welding.
