Default Choosing a servo

I am in the process of upgrading servos. I know digital is the way to go as it provides more 'holding power' I am just wondering between speed and torque, what is more important?

I am using this on a 1/10th scale Electric touring car. I have a KO301F receiver.

Whats a good servo out there now? I currently have the KO2173

For touring cars, speed is more important. I'm running a Futaba 9550 digital. Speed is .11 torque is 83 (I think) Car handles great.

Hi,


I'm answering my own previous post w/ this one but here it goes: I've made the decision of using KO2363 as my primary steering servo for all of my on roads. I've installed the KO2365 on my mtx4 as it is supposed to handle a greater "beating" yet still has the same specs and weight as the 2363. The 2363 is a digital, self centering, ics-compatible FET servo which is great if you're using a KO radio like the EX-10. The futaba s9550 is also a great servo. One of the racers at my LHS uses that one and it gets the job done from what i hear. I would've went that way myself but since I've got the coin to spare, I stay KO...Just personal preference. <<short version>> i'd say go with the KO 2363 or the futaba s9550. Good luck.

Looks like the 2363 has the same specs as my 2173 only it is digital.

I guess my question is coming form the same spec will i notice a difference with using a digital servo ? Im just trying to justify the cost.

The digital servo will track better. Numbers aren't accurate but a comparison would be that an analog servo looks for center 10 times a second. A digital servo looks for center 100 times per second. That means that a digital servo holds its line better.

I've had very good results with a KO 2123. It is very fast, very strong and can take lots of abuse without breaking. I've also had good luck with the Futaba 9541. That one is in my 6 year old son's car and he drives it hard, but it has had no problems.
