I would tend to agree with this, The 10A Sabertooth will hold out until you get a significant stall current for a while.Quote:

In my experience, the sabretooth 10a handles 2x 12v drills at 14.4 volts easily.
The only time I ever blew one was when I burnt out a motor at the same time with the help of Little Hitter. So, I think that the Sabertooth will do you fine,
and have better control than the electronize. This is just my opinion, and its all down to personal preference really.
id like to second what alex said , the sabertooth handles 2 14.4V over volted drill motors in my FW no problems , and it has good over current protection so its pretty hard to kill , one thing i would advise though is giving it some sort of heatsink as it can get quite toasty running on 14.4 V , it also has thermal protection which it has only ever stopped on once , the heat sink solved that.
Oh and argos drills are 10 quid each :D ( and i cna confirm they work just lovely with the sabertooth 10 A)
i second that they get hot, but dont blow unless you stall them for ages, or overvault them to stupid voltages they will be fine :)
oh and tom (muchalucha) can u come on msn, got some stuff to tell ya

Not all drill motors are created equally. Granted you may well be fine if you don't stall them etc but I would always recommend over rating everything in a machine. Any robot is only as strong as its weakest part, which I have found out on several occasions the hard way.
mainly now im looking at the sabertooth 10a, it seems to have everything i need, but just checking around as if i broke thats 50 quiid down the drain, buying two of the 14.4v drills from argos, as 4 would mean id need two speed controllers somebody said, but if you kno otherwise please let me know, most things are sorted and should have GIZMO, mostly likely to be its name after my cat, up and running by early 2010, thanks again for everyones help in this, ive really benifited from it, see you at some event somewhere :)
you can put 4 drills through a dual controller however you will definitaly kill the 10a sabertooth doing that
sorry to bring you down mate but iv already used the name gizmo for one of my feathers
thats fine mate wasn't sure anyway, think im going for a two wheeled invertible wedge shaped robot, some big tyres for traction, and may look over drills for more pushing power, as most robots use them, would need help on a speed controller to suit this though
to clarify , the sabertooth will handle 2 drills but not 4 , for 4 all i can recomend is the 40 A electronize's or my 30 A team thants speed controllers
