will a belt whit a pitch of 2.5 mm be enough if (i juse 2) to power my 2 kg disk?
wont they tear

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

would this batterys be good for an accu?

let me know

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.

what is the differends between these batterys:

and these sanyo cells:

(accept for the capacity)

why cant i juse AA baterys?

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.

ok,
tanks 4 the info

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.
