Clive,

Should be ok. My problem was that I was using 20 nicad cells which never gave a voltage higher than 25V (should be within the controller limits) but they say you shouldn't use more than 18 cells and then there was the fact I was overvolting. You could always jst take the safe route and use the 12V gold motors.

Having sold hundreds of the Dimension Engineering controllers, only about four have failed of which two were from Gary. I never advise on suitability of using drill motors unless the spec can be produced for them. Over volting drill motors is an added unknown and is at your own risk really. 24V Gold's should be fine, I'm not comfortable using 12V Gold's though as it is a bit borderline.

Lol not sure if I should be proud of that or not :blush:

I guess it is some sort of claim to fame.

Thanks guys.

i have 3 sabertooths, never had a problem running 2 x speed 700's, or 4 drills on 18v, had a duff one once which was faulty from new, but apart from that i think they are a great controller, dimension's after sales was also brilliant when i had the faulty one, they sent me a replacement without wanting the old one back. (brought mine from gimson robotics, before it closed down) i would recommend getting one from technobots as you get the discount? also they take a while to arrive when ordering direct from dimension.
i think 24v is the max you should put through them though, also obviously you want the 25a not 10a.

Thanks for all the feedback guys, it looks like i will be saving some money for a Sabertooth.

Hi I've just fitted the new sabertooth speed controller to Tron and sometimes its ok then the thing goes crazy
It is connected to 14.4v batteries running 2* 9.6v motors per channel. Spectrum dx6 radio switches no 1 and5 down as per instructions.
Normally it works well then it will go mad I loose all control and if I turn off the Tx then it still moves with no reaction to anything I remove the link and replace then it is ok again. I have noticed just before the problem starts the red led flashes fault then the fun starts any idea.
Also when wiring the Rx into the speed controller do you put two 5v power lines and two 0volt lines from the two channels or just one I€™ve tried both dosen't seem to make any difference.

So you are running 4x 9.6V drills overvolted to 14V off the sabretooth?

There might well be another problem with your setup but that sounds like what happened with my sabretooth before it let out the magic smoke. I would drop two of the motors and try one on each channel and see if you still have the problem.

If you are running 4 drills, you are running it at its limits.

Just one.
