Lol man i'm too bussy to make a tutorial on animating plus i dont have xsi mod tool so i don't know how to use it, you should ask minilogoguy who seems to know how to animate things in xsi mod tool, he may teach you. Anyway I have the juggernaut half weighted i believe, i don't know why i stopped on animating it, probably because i left modelling for a long time i can finish it since its only one animation (moving wheels) but i'd send you the .glm with the animations and you'd have to put it ingame and all that annoying work, you decide.
And yep, thats the mod .
