sorry i have so many stupid questions.
2nd link doesn't work.
fixed it
I think the scooter motor will be more powerful but that's just a hunch. Both motors would need gearboxes though, with the scooter motor it would be fairly easy to have a reduction using chain and sprockets but for the Mikita motor you would probably need the matching gearbox. If I was you I would go for the Gimson motors or Argos value £12.50 cordless Drill motors for your first bot, they are very simple to use and ou don't need to worry about gearboxes.
For my first bot I tried to use windscreen wiper motors despite everyone advising otherwise and still haven't managed to finish it due to complications and difficulties only caused by the motors. But I have managed to make 3 robots using drill motors and robochallenge wheels, it's just so simple!
The Makita motor is the more powerfull, smaller, lighter but with a much higher RPM.
The scooter motor is large and heavy, but with the lower RPM easier to work .
Concerning batteries. you can't do much wrong with the vapextech one. But you'll need 2 of'm for the scooter motor, the Makita can work on the 8.4V of the first Vapextech pack.
any links for good drill motors?
are u after 12v or higher

ive used argos ones in my 4x4 robot and they are defiantly cheap and cheerful but for my second robot i found these http://www.ebay.co.uk/itm/BRAND-NEW-GEN ... 35b8213ae2
they work out about the same but you don't get any battery but most people don't use the drill packs and they are better build quality and a bit faster
the seller also has some more expensive and more powerful bare units
thats really helpful but will they power my robot
