The tool seller at my local car boot sale had Nutool 30v cordless drills with charger and two battery packs for £30 each.

The challenge 24v drills at argos are half price are they any good?

[ewan]

Drills

Yeah, but having two back-to-back in a feather takes up a load of space.

hmmm how much space? How about 14.4v or 18v?

[ewan]

Drills

Well, more space than 12, 14.4 and 18v drills which all usually have the same motor (550) and gearbox.

wonder if anyone can give me a hand.

I was hoping to use a drill motor but because of space that may not be possible. I am looking ideally for a motor thats 5cm in length with the same power and weight of a drill motor (just over 200g). The diameter does not matter. It will be used to spin a 2kg disc so something that is more torque than rpm would also be good.

I doubt there is anything out there but thats why I am asking you guys!

Depends on your budget - have you looked into an Astro Gary? For a spinning disc an Astro is one of the most popular at the moment.

Maybe a mini ev with a drill gearbox on it ?

budget = cheap

The mini ev is availible in some Euro cars powering the fan motors or heater fans .

Id advise against using the Mini EV at 24v, or even 18v under too much load, ive blown a couple that way. Id be very surprised if you could get anything very cheap which is that small and that light. Cobalt flight motors or brushless motors, maybe, but thatd be a costly alternative. Id go for thingaps on a BIG reduction, friction maybe, if I had the dosh (http://www.robotcombat.com/images/TG3200_series.pdf)

You might want to look at HTI Replacement motors here http://www.robotcombat.com/marketplace_motorsmisc.htmlhttp://www.robotcombat.com/marketplace_motorsmisc.html cheap, but youd have to pay the postage from the US

A few of these maybe? (three might just do) http://www.distel.co.uk/asps/details.asp?ID=38018PT18&ER=0.5475&CY=USD&AP=32.88http://www.distel.co.uk/asps/details...Y=USD&AP=32.88

something like this but a bit bigger would be ideal

Julian, those are the ones we use. We remade the gearbox and its smaller than the 18V ones and fits entirely inside the wheel.
