I wouldn't go with anything less than 180 oz/in of torque, metal gears, and a coreless motor. Speed is good, but strength is better when it comes to steering and braking. Unless you have previous experience with digital servos in a nitro car I'd stick with analog as they can take much more abuse than digital without burning up.

there are some good ones. whats your use. bashing/racing?
whats your budget? 100.00 for both or 100.00 each?
whats it going into?
one or 2 steering servos in your rig.

what kind of brake setups?

like noted above there are some minimum specs you should look into for the steering and then again for the throatle/brake servo.

steering usualy torque. i recomment 200 plus in/oz for steering and not slower than .16ms speeds.

thrt/brk i recommend not less than about 200 plus In/os for a rock solid brakeing ability, but as fast as possible of a servo, under .13 is better imo, for the troatle response of it.

Personally for steering i mostl use th JR Z9000T servo. 322 in/oz of torque at 6v, and .15 speed. also actually pretty good for thrt/brake too.
but for a good TB i recomment the JR Z9000S , about 220 in/oz of torque, but has about a .13 speed. both are Ti Geared, digital, dual BB, and run about 115.00 each.

right now I have JR9000T for thr/brk and for steering I'm using Ace 1015. This is set up in my truggy and buggy. I love the steering speed of the Ace. It seems to have plenty of nuts for the truggy. I have placed well when racing with this set up. But I need the speed to make up for my slow brain and overshooting the corners. LOL

those are all great servos..

But 200 oz for a buggy in steering is a little steep.. yes the theory more is better. but the way his post is worded seems like he was looking for a baseline..

I would say nothing under .15 on throttle.. and you want atleast 100 oz.. to clamp the brakes..

Steering.. I would say nothing over .16 and atleast 125 oz.. should do you well..
But if your a smooth driver you may be able to get away with a slower steering servo... if it has more torque..

I wish you luck..

Personally I have had good luck with FUtaba JR.. and the Ace servos.. Hi tec,,, ( works in a pinch..) but are usually sold off for something else had a few go bad with endpoints set properly...

I've got a pair of air 358's in my CEN buggy, and an Ace 1015 for steering and Ace 1313 for throttle/brake in my MBX5. I also have a pair of 358's in my old T maxx race truck, and I used the Air 358's for both when I ran truggy.

For 10th scale I've always used HiTec 645MG for steering in both nitro and electric, and HiTec 625MG for throttle/brake in 10th gas trucks. I've only got one 625, but I've got several 645's as I used to run electric buggy and truck as well as 10th gas so I needed more steering servos than I did throttle/brake units. All these 10th scale servos are at least 3 years old (some are much older than that), as it's been that long since I ran any 10th scale and all of them are still working just fine.
