I want a good servo, sumthing that will hold up. Qualities iam looking for:
1) Steel geared, and what not
2) High speed/high torque
3) i dunno if i can use digital ones with my radio, if so then id prefer a digital one
4) resonably priced

Any suggestions?
IMHO, to match your MX-3S i suggest:
1. digital and coreless motor servo -- High speed response, good holding torque, slightly noisy on idle
2. torque should be around 8-9kg/cm for on-road use

these are the servos : Sanwa ERG-VX or WRX (digital 0.06-0.07sec/60 deg, 8.0-8.1kg/cm), Futaba S9451 or Hitec 5925
I'm using ERG-VX with JR-XS3 then set the response parameter from N to F (Fast response)

if you look for cheaper one, I suggest Sanwa VB (analog 0.1sec/60 deg, 13kg/cm) should be more than enough for on-road..

Actually, if your digital servo is "slightly noisy" at the centre position, (Without any load) That is not a good thing, It means the servo motor is constantly hunting for the "centre", and over a long period of time a flatspot will develop. The solution would be to program a slightly wider deadband at the centre position.

Hope I'm not opening pandora's box with the above statement.

Ok from your suggestions, i like the S9451 so far. But what about the one i found? is a S9404 and the person that has it atm says he used it for racing with a VERY similar setup. Is this one any good? I looked it up and it seem great. Metal gears, coreless motor, ball bearings, .11sec / 60 deg, 5.7 kg torque. How about this one? i really dont want to spend money if i dont have to. Iam not going to be racing, its pure going to be parking lot basher.

I use a Futaba S9451 along with some other guys at my track and they always work perfect.

Its actually a Heli tail rotor servo, it has 2 ball bearings, metal geared, 3.5kg torque, and 60degree transit time of [email protected] Not only is it strong and fast, but its super super smooth and has very little resistance when the servo isnt on.

They're not cheap, but any other servo i've had is crap by comparison.
3.5kg isn't enough, you'll strip gears every day of the week

on general, most decent high speed servos are like 7kg+ but a lot are around 9 now, then the high torque servos are around 13kg.

I'm agree with raving-monkey..
I think 5.7 kg/cm of torque is at the edge,
but again its depend on your kind of tyre, track grip level and temperature, if low grip ashpalt 6kg/cm it maybe enough, but when grip level increase you might still feel little laziness on steering response,

Its worthed to invest decent servo for your car, will save you unnecessary broken parts cost on crash or entangled with other car on race or bashing coz you will help you keep precise racing line.
You might need test S3003 against low profile S9451 on your car, setup and equipment, and you will notice how different your car response to your command

Ghostfit,
I will set some percentage of steering deadband this weekend, thanks..

Pound for Pound, I think the Futaba S9550 is the best servo.
0.11 sec/60 deg @ 6V
6.0 kg/cm @ 6V

all this, not to mention its low profile, so you gain valuable chassis space.

It will set you back about $65 USD from Champ R/C

Best out there IMO

in my opinion, a servo that WORKS is the best servo. I've had some servos do some breaking on me. That's what I get for smacking it into a wall :P

Joking aside,
I personally love my Futaba S3152 digital (I think that's the number). Digital servos are quite expensive, but definitely more precise. Not needed if you're a basher. This servo, though, is plastic geared. But if you're on a budget, this would be the way to go. It put a slight tend in my pocket, but it's been super precise, even after a few corner dot jumps :P

AND, Surikarn used it when he won the ISTC world championships in 2002 and Rheinard used it in 2004 at the world championships, which he won.
