Gotcha, I guess it makes sense really with the weight difference between a feather and a heavy everything is going to be strained that much more at 100kgs. Thats interesting I never realised thor had run a electric set up, terrorhurtz is the main inspiration behind what im planning as im sure many others before me - am I right in thinking john reid was the first to come up with the rack and pinion method? So simple but so effective.

I have been wondering about weight, specifically when it comes to weighing a robot that uses gas I assume its weighed with the bottle full? I have a standard 12oz paintball tank that im going to use, if anyone knows roughly what one weighs when full?

I may as well start my own thread at this rate lol
