Sabertooth 2x25a Problems??

[webby]

Thinking of buying a Sabertooth 2x25a for a project, when asking around at GSL people were saying they kept breaking? Would anyone recomend these?

I found them very easy to set up, haven't had any problems apart from connecting battery wrong way round after which dimension engineering replaced it free of charge apart from postage

cool, thats very kind of them too lol

I wouldn't bother. I managed to fry two of em in quick succession a while back on regular drill motors. They don't have a 25a continuous rating or anywhere near that. Get some botbitz or reprogram a couple turnigy 85a

Ok, what controller would you recommend for wheelchair motors?

[typhoon_driver]

You were looking at using one on wheelchair motors?! It would have certainly blown.

What is the application?

[webby]

On YouTube ect they use 2x25 for the controller

I definatly wouldn't use a sabertooth for wheelchair motors- they're good if not pushed close to their limits.

I'll ask again, what is the application?

The robot will weigh around 100kg but is
Not a heavyweight.

That leaves a few options, Mr Cryptic...

1) it's a house bot
2) it's a walker
3) you're entering superheavyweights somewhere, despite being under weight
or 4) it's non combat

Gary is trying to help you, but the question is what are you trying to achieve with the motor? What kind of strain will it be under, and what kind of performance are you looking for?

I'm assuming this will be the drive for what used to be the Robo Challenge house-bot?
I've never used a Sabretooth but have heard mixed reviews (although their customer service is excellent); I would tend to opt for a Scorpion XL/XXL, they seem to be a bit more robust for robot combat applications.

BUT, yeah don't use either for wheelchair motors. Get some heavier duty controllers. BotBitz 85s/self-programmed Turnigy 85s, as Gary suggested, are pretty sturdy and low-cost for the size of application.

Great thanks, forgot about scorpions
