What servo are you using?
 

what servo are you using, how much you got it for, and what do you think of it? im planning on getting one for a reasonable price, so please post your setup.

RE: What servo are you using?
 

in my buggy i use the KO Propo PDS-2366 for steering and the KO Propo PDS-2365 for throtle they were $125 each and they are awesome. best servo's i've owned.

RE: What servo are you using?
 

I've just got a sanwa/airtronics 94359Z (ERG-VZ). I've only used it twice since I put it in but I am impressed. MUCH surer steering and all metal geared. I'm using it in anger later today so I'll give you a little more feedback then. It wasn't cheap though $92

RE: What servo are you using?
 

for my steering i use a futaba s9351 which is about 110$ and for my throttle a hitec hs-5625 mg get the job done just fine. goes for about $55

RE: What servo are you using?
 

darthablls have you ever put the 5625 in your steering? how is it?

RE: What servo are you using?
 

I have been running the same servos in several of my vehicles and they are the best...

RE: What servo are you using?
 

I'm using a Hobbico CS-70 in my Hyper 8. I'ts only $35 and it runs great.

4.6v- 106.7 oz

6.0v-133.3 oz

I use a KO Propo PDS-2344FET for steering and a JR Z590 for throttle. Any servo from this list should work great for steering duties:

There are alot of good servos that you can use as a throttle servo as they don't get as much stress put on them as a steering servo does. Anything w/ 85+oz torque, .15 or faster reaction, and metal gears would do fine. Stronger and faster is a bonus, but not as critical as your steering servo.

RE: What servo are you using?
 

I am running Jr-650 for Stearing 142 oz $50 and JR-590 89 oz for Throttle $39. When I get some extra Money I will probibly go with either the Airtronics or maybe the Kopropos. In the Mayhem ST we are running 590 Throttle and JR z9000T for Stearing $114.

RE: What servo are you using?
 

Airtronics 359Z($90) and 360Z($90) in my buggy and Hitec 5945($80) and 925($55) in my GT.

RE: What servo are you using?
 

I run ACE DS1211 on throttle and brake and DS1015 on steering, awsome combo IMO

RE: What servo are you using?
 

Futaba S3305 for $35. Servos don't help you go any faster so its pointless to spend $100+ on a servo. I'm racing just as fast with this S3305 on steering and throttle/brake then I would be with a digital servo. If you have the cash to spend the digital servos are nice to have just because of their speed without losing any torque but they don't help you drive any faster at all.

RE: What servo are you using?
 

This is exactly what allows them to make you drive faster. They provide the same (or better) torque, but allow you the ability to make faster corrections and direction changes. You still haven't tried one yet since we had this discussion last time. I can tell, because you would have changed your mind already.

EDIT: That is not just digital servos, but coreless units overall.

RE: What servo are you using?
 

I have tried digital servos on other cars and I did borrow one from someone at one point. I deffinatly loved how responcive it was but it didn't help me drive quicker lap times at all. The only reasons I could see for getting a coreless digital servo is to avoid over drivers easier even though it will only give you maybe an extra inch and just the fact that its faster but in my opinion its not worth the $65+ difference. I'd much rather put the cash into tires, glow plugs, fuel, and engines.

RE: What servo are you using?
 

If it could help you avoid another car, could it not also help you make quicker corrections to your racing line? Anyway, agree to disagree I suppose.

RE: What servo are you using?
 

Actually when I get loose 80% of the time I'll still over correct even with a slow servo. Either way its still not worth the price difference. If I had pleanty of money to spend sure why not buy them along with a factory racing engine, tires for every single race, and all of the other best equipment that money can buy.

RE: What servo are you using?
 

5645mg steering

RE: What servo are you using?
 

Note my avatar: I drive a crappy buggy (which was used and abused before I bought it), with a worn out OS RG, my last set of tires only got replaced because I wore a hole through them, and I drive on a track we don't bother to water anymore because of how rough it has gotten.

Despite that the difference in handling due to my servo (and absolutely nothing else) is blatantly obvious. I can drive deeper into corners, and my car is quicker to react to corrections made when bombing through the rough stuff. And, unlike any of the cheap servos I had previously, it still manages to re-center itself while going down the straights after a couple weeks of use(no more holding the wheel to one side to go straight). I am not saying it because I am high and mighty and think everyone should kick in for a Nomadio equipped, Mr Ninja powered, Inferno SP2. I am saying to get a good servo because my cheap ***** tried it and it worked better than I ever could have hoped.

RE: What servo are you using?
 

I know what your saying but I've never had a problem with the S3305 centering itself or lacking on torque. Its a little slow but its still enough to have quick enough reactions to keep up with the quick desitions you need to make. I have had one fail on be but I think moisture got in there which burnt it out otherwise the S3305 has been bullet proof and 90% of the racers at my local track use them.

RE: What servo are you using?
 

nope haven't tried it don't think i ever will as it looks a whole lot slower then my futaba. and it think it has something like 70 oz-inches less torque. works fine for braking and throttle though.

RE: What servo are you using?
 

I use an Ace 1013 for my steering 180in/oz and .09sec. it cost me $109 aus (about $80us). I am very happy with it and plan on getting another one to put in my other buggy.

RE: What servo are you using?
 

Perhaps Futaba servos just are a cut above the Hitec, JR, and Blue Birds that I have tried. How long do you actually get out of one of your S3305s though before replacement, and how many hours/week do you drive?

I have been hearing lots of people say they liked their Ace servos. I am thinking about getting one for my throttle servo since you can usually find a good deal on one of their high end units on e-bay from time to time.

RE: What servo are you using?
 

What is the minimum torque and speed you recommend for a 1/8 buggy for racing? I am not talking about just getting by!
Thanks

RE: What servo are you using?
 

Super Dave and I struggle on this one, but I would say (in order of importance):

- coreless motor
- metal gears
- 150 in/oz or more for torque
- .15 or faster reaction time

I did some math, if you take your average 8.5lb buggy, and convert that to ounces you get 136. That means that if the servo directly supports the weight of the vehicle, anything less than that couldn't support your car. My guess is that there is some leverage involved in the steering system to reduce that load, but then you have to add for speed. F=MA if you remember from physics class, so the force required is equal to the mass of an object multiplied by its acceleration. Acceleration in this case is angular, as in how tightly you are trying to turn. The more torque available, the more your servo can hold its position at speed when you crank the wheel.

Servos are always a trade off between torque and speed (they have internal gear ratios just like your buggy that determine which that model will be). But some of the high end units from Airtronics, KO Propo and ACE are pushing 180+ torque and .10 or faster transit times. The difference between .20 for an average servo and .10 seems small, but if you look at it the difference is half. That means that your wheels will be able to steer twice as quick from side to side, and with the torque backing it up, they will stay pointed where you want. You can see how that translates to better response from what your fingers just did, to what your car is about to do.

I guess what I am saying is that if you are shopping for a servo, they all look the same, but you will be shocked at what one of the more expensive ones can do compared to your stock unit. I was anyway.
