I Need a Good Steering Servo

The only problem with the heat sink cases is they weigh a lot.
For 1/10th sedan: If you are buying a new servo, try the Futaba S9452. If looking for a used one then look for the S9451. They are basically the same, but the 9452 is smaller and lighter.
The airtronics 94357 is a good servo also as well as its heat sink case version.
With a steering servo (lay down) I have always been concerned that with an aluminum case the heat sink might work against the servo. If it lays on the chassis, and the chassis warms up, the servo case might be a heat sink for the chassis instead of the other way around. All I know is I have never owned a heat sinked version of my servos and so far I have not had a failure. The futaba digitals are good servos, and the pricing at Tower Hobbies is very good compared to their competition.
Watch out for the coming S9551!!

I have had excellent results with the hitec HSC-5997TG for steering. It more torque than some of the others mentioned here at a sacrifice of a little speed. For steering, you need a servo with some decent torque numbers because all that front drivetrain spooled up to 60 mph diving into a sweep gets pretty hard to turn. I usually use a Hitec HS-6985HB for throttle with good results. this servo has the Karbonite gears. The only problem with the 6985 is it is evidently a pretty popular servo and is backordered alot.

Servo is not on your website right now. Through GP I have not seen it available, and it is 25% more money than the 9451/9452. Still might be the way to go in my future. Either way, I am waiting on the S9551. Less money, more torque, and 5-10 grams lighter. A touch slower though.

And whatever you do, dont fall for the digital servo high current draw myth. Most digital servo specs will bear this out. Testing I have done over the years shows that most analog sevrvos will draw around 1 amp cycling the throttle and steering. Digitals are usually around 1.3- 1.4 amps, yes more but a really insignifigant amount considering the current high capacity RX batteries now available. Benefits of digital far outweigh the additional .4 amp draw. One caviat to this......if any part of your linkage is binding digitals WILL draw signifigantly more current than analogs trying to move the binding. Yet you can be driving around oblivious to the linkage problems because the digitals torque does an excellent job of masking any binding in the linkage. If you run digitals and your linkage gets wadded in the middle of a race, your RX battery can get crowbarred into submission before race end and you will never notice any difference in steering.

Do you consider $100+ servo expensive or peace of mind ?

I don't know if you are asking me or not, but I think $100 is expensive if you are talking about a servo that performs like a 9452 or a 9551. The futaba digitals have proven to be a good servo so I think they set a new level of expectation. While I would expect a brushless servo to draw less power and the motor to last longer, neither of those things are issues to me at all. The brushless servos also seem to be quite a bit heavier than the 9452/9551 but will certainly lighten your wallet.

JR 8711 is the servo that would assure good steering.
