Cheers mate that's cool I'll have a look. As for the time I have the equation for that somewhere at home. Cant use the batteries I have, there way too heavy. I'm gonna look into some other lead acid batteries but go for ones with as low amp hourage as I can afford to go as to save weight. My plans are far too complicated I think already for the weight limit. My dad is gonna show me how to cad It. He says we can find a weight and even stress test it (get me) and see where to go from there. Now I think I have all the info I need. (cheers guys!) hope to be fighting as soon as and hopefully with a good reliable machine! I'll try and make some sort of a build diaray along the way too.

Cheers guys
