Yea I have just motors and all the gears that came out the chuck heads, one if them was he of those £14 from b&q so might just go grab another one off those and take that apart, for wheels I might just make my own and for armor im not sure where to get HDPE from, and the flipper system I'm making my own, I'm doing trials with 2 liter pop bottles and push bike pumps as rams.
