More volts is better in your case, but it is still possible. How much weight do you have left? Belt drive is better for the disk motors.

im still disining the robot on paper (its my first one im desining by myself) i have not calculated the weigh jet, but im gonna do it soon...
and from the gold motors to my weels also beld or is it better to juse chain then?

I would stay away from chain drive. Specially in a feather, since chain is heavier then belt, and the motors tend to get less of a beating.
Now I know there are several robots out there with chain drive and perform very well and yadayadayada, but it is still better to have belt drive.
ok so its beter to juse belt drive everywhere...
i will take a look how the HTI motors will preform on 14.4 vols, and if it prefomes bad ill take 24 volts...
what is better to juse timing belts:

or this belts:
http://www.robotmarketplace.com/marketplace_timing.htmlhttp://www.robotmarketplace.com/marketplace_timing.html
and witch pitch do i need(if i take timingbelds)
a 0.080 Pitch or a 0.200 Pitch?
The smallet the pitch, the smaller the pullies can be. The smaller the pully, the lower the weight.
Also, why would you order a thing like that in the US, and paying lots of taxes and transport, when this is stuff you can find localy.
but will the smallest pitch be strong enought
(if i juse 2 belts) to power my +/-2 kilo disk?
wont the brake?
do you know a place where i can buy stuff like that in holland?
I dont know directly where to buy it in the Netherlands. As I live in Belgium.
But Inventor, Cavecrusher and a few others on the Dutch forum do.
http://www.conrad.nlwww.conrad.nl has drive belts.
So do http://www.rs-components.nlwww.rs-components.nl
will this beld not tear (if i juse 2 belts and 4 pulleys)powering a 2 kilo disk?:

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:
http://www.mnm-computers.nl/images/Batterijen/GP_AA2500.jpghttp://www.mnm-computers.nl/images/B.../GP_AA2500.jpg
and these sanyo cells:
http://www.accushop.at/images/3600HV.jpghttp://www.accushop.at/images/3600HV.jpg
(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.
Nimh is getting better and better in providing large currents, but is still a long way of from Nicad. However, i decided on going with Nimh simply because they are lighter.
Still the Sanyos i have manage to squeeze enough current for my feather and heavy.
But not the AAs, Sub cs.
