My irritation at the paint comment was mainly aimed at Andy for reusing something that wasnt funny or especially relevant in the first place :P I would raise some poitns but my brain is abotu dead at this time of day...

Mark: At a quick break down of your weapons still a 30kg flywheel is only ever viable as the only weapon by my reckoning - thats 30kg + probably up to 12 (?) further kilos for motors, gears mounts and so on, then you add in canisters rams and whatnot for the flipper and you are looking at approaching 60kg worth of weapons. Then you have 4 motors and tracks adding upwards of 30kg at an entirely uninformed guess: thats 90kg of robot and you havent even got a chassis or armour yet.
