I have a KO 2143 Servo in my XXX-S. This is my first Digital Servo and I really like the power and speed of it. I also have nailed the boards a couple of times with it and could have sworn on one of the hits that I totally screwed up the Servo but there was nothing wrong.

TFR- As long as the car will drive straight with that servo I don't see any reason to put a high end servo in that car- espescially considering its basically a pan car and you probably just drive it around for fun. Nearly all the manufacturers are using Futaba compatible plugs now if you ever get the urge to upgrade in the future though.

Well I don't know who actually makes the fastest servo, but the fastest that I have seen on paper is the Ko Propo 2015 with a transit time of .05. Of course that is FET boosted and rated at 7.2 volts where as most everyone else rates theirs at 6 volts. Actually if you hook the Ko servo up through your speedos FET wire it is only going to get 6 volts anyways. From what I have seen all the Speedo manufacturers only supply 6 volts through that wire, in order to get the 7.2 volts you would need to hook the servo up direct to your battery packs positive wire! I think the 2015 has at least 95 ounce/inches of torque, which is more than enough for most applications! Of course the amount of friction and binding in your steering setup will determine the servos actual speed and that is where the torque comes in! Either way if it is as fast as they claim, I guess it would be the record holder for speed! I have some older PS-1001 servos and two 2015's and I will say they are fast as hell and have great torque, I have one in my XX4 and it has more than enough power for that, and there is no lack of speed!

I run my F103RS with a 13T motor and a Futaba S148 (old version of 3003). Runs fine with no problems at all! Due to the lightest of these cars and the direct steering linkage you really don't need anything special, however, I would recommend you upgrade to the Tamiya high torque servo saver (white nylon). This will give you better leverage (faster transistion time) and less play in the linkage.

darkside if you want a great servo at a great price, depending where you live and it still would be worth it, Hobby People is having a labor day sale this weekend until monday. All Cirrus servos are 33% off! Get Cirrus's CS-65BB Coreless servo. It has a transit time of .12 and 121 oz. of torque. More than enough to steer a touring car. It has double ball bearing and uses a 9 pole coreless motor so it center very well. The normal price of this servo (already a bargain) is $47.99, but with 33% off its a steal at $32.15 maybe plus 5 dollar shipping depending or if you can go to one of the hobby peoples, they would add tax.

i currently have a futaba s9402 on my tc3. would upgrading to a digital servo such as the 9450 be worth the money?

Once again, thanks for the responses and keep them coming.

I don't know much about the digital servos. Do they have an additional wire that gets connected to the speedo, like the FET boosted servos?

Darkside, nope...The digital servos hook up just like regular servos...Difference is they are digital, so they're more precise. I haven't tried one yet, but when my JR wears out, I think it will be a good investment. porky's suggestion sounded like a very good deal though!

Speedo: Yeah the Cirrus servos are one of the brands that I have been considering. After listening to all the suggestions I have raised my standards from the .17sec range I was looking at, and will go for the fastest, highest torque servo I can afford when I'm ready to buy. I might even go for one of the digital units. I'll have to see what I decide on. There are some really good servos out there. Anybody ever use Mutilplex? I'm not that high on the bright red case, but are the servos good?

Are you sure it's 33% off cause it still says it's full price here. http://www.hobbypeople.net/gallery/444124.htm

You will notice very little difference between the 9402 and 9450 (if any at all!). The additional holding power of the 9450 will not be noticeable on a TC3. However, something like a KO 2143 or 2123 will be more noticeable because of the faster transistion speed.
