i just got a jammin scrt10 that came with a losi digital servo. the losi servo feels really stiff, its hard to move it with my hand. i dont know if thats normal for that servo. i think im going to change the servo, im looking at a hitec 5625, it has 130 oz/in and clocks at .14 seconds. do you guys think that it has sufficent torque and speed? im trying to stay around 40 to 45 dollar price range.

No. I'd definitely want something with more oomph in a 4WD SC. I agree that one of Hitec's offerings will be your best bet in that price range. You can also find great used deals here on the forum.

That servo is adequate for what you want to use it in, it's just a tad slow.

130 is plenty for a 1/10th scale.

I don't agree with the above 2 posts, 4x4 SCTS are big and heavy, I would want more torque than that but in your price range it's gonna be hard to do.
XP 1015's are 200oz and .10 sec. but they're also about $80...

Adequate means that it will turn the wheels, is it a good choice? No, but it is cheap and may last for a while. I have one of these and use it for a dig servo on my Axial, it does that well.

The $ limit imposed by the OP means that he is bottom fishing and doesn't have the option of getting a decent servo, therefore the OP has opted for a marginal servo.

130 oz means that with a 1 inch servo horn, it will lift 130 oz or over 8 lbs. That is enouph to turn the wheels just fine.

When I started racing back in 1988, standard servo's had about 40 oz. The best servo you could buy was an airtronics 151 and they didn't even have 130 oz of torque.

I'll agree with that, yes it's adequate just not optimal. It may work perfectly fine for the OP.

At the same time back then we weren't trying to turn big heavy 4x4 trucks running 40mph though. I still have a couple Futuba 148's laying around.....somewhere

130oz. may be just fine for the OP

I love this servo. It costs a little more than the mentioned hitec servo but it's a great value for what it does. 166 oz. torque and .08 sec transit time.

grrr it won't let my post links yet, but the servo is a Spektrum S6040 and it's $79. They also make the S6030 which has 278 oz. torque and .15 sec transit time. I would go for the faster one though.

I am currently using an Align DS610 which has almost the exact same specs but can be had for around $50-$55 shipped. At least that's what I paid for one about a month ago on ebay. Works great.

I have the same servo in my Hyper 10SC, been in there for almost a year w/ about 30 races on it. No problems at all. The torque is perfect just wish I had a little more speed sometimes.

As I read down, I kept thinking that someone HAD to beat me to this!! lol

Savox servos are great; they're fast, strong and (at least the ones I use) have titanium gears. And they have several in your price range that I think would be a LOT stronger/faster than what you're currently using. Good luck!!
