ill go direct drive then, that makes it a lot more fun
how does one of those ninco stingers (nc-3 or nc-5) compare to an fa-130 motor (the little blue capped ones you get with the tamiya gearbox kits)?
they are supposed to have twice the torque of two fa-130s combined and im interested in using one in my 450g sozbot, to spin a 150g 90mm disk through a 2:1 belt reduction.
not sure what voltage they run at but i was planning a low voltage like 4.8-6v. reckon a ninco would fit the bill?
on a low voltage you might run into troubles. Stingers etc are designed to run at 14.8v iirc. So on 4.8v you are looking at 32% of there intended voltage.
The standard tamiya motors might be better.

ah that could be a problem, can any one recommend a high power motor that runs on ~4.8v and weighs about 50g max?
a BB280 (54 gr), or a 280 RACE(40 gr)
if your into home-built stuff, why not check:
http://homepages.enterprise.net/jayjay/cdrom_motors.htmhttp://homepages.enterprise.net/jayjay/cdrom_motors.htm
Brushless motor that gives approx. 5 amps, 24 grams, and almost costs nothing
(except the ESC )
If they can hold 280 gr on half throttle, they should be ok for ants.
EDIT: you can just adjust windings and thickness of wire to get the max. power on 4.8 v.
I used a motor out of a CD-Rom once, it was slightly different to the one in the link, the one I used was what moved the CD tray in and out, but when I put it into my rather over-weight super-antweight it seemed to provide a helluva lot more torque - or in this case, hitting power - than a standard hobby sized motor. I dont know how handy it would be for antweights but it could be powered off of a 9V battery which saved some space and weight compared to the 6V battery for the hobby motor. Its also quite flat compared to the hobby motor which was useful if the design was particularly slim. Hopefully theyll come in useful to someone
Ive made an ant with a harddisk motor once:

It was withing the weight limit, but no armour or anything. I have to update the micro because I speedhacked the servos and now its uncontrolable.
