    I would use the 6mm chain from technobots. Its very light and would happily power the disc.

    no, for one they are Nimh and so cannot provide large currents and 2 they look a bit cheap and so will probably not do too well in combat.

    well the first set are AA batteries, and will not be able to supply enough current for your motors. The second battery appears to be a sub c cell. These are capable of higher discharge rates than the AA battery and are much more suited to combat robots. I beleive the second battery will be good enough for you to use as scorpion evil runs on 3700mA sub c nihm cells with astros.

    Two quotes from above;

    they are Nimh and so cannot provide large currents

    scorpion evil runs on 3700mA sub c nihm cells with astros.

    Who is right? Im betting that Nimh can provide large currents.
