Default Throttle Servo Torque

Is there a minimum / maximum amount of torque that a throttle servo should have?

Thanks!

Ten years ago the top of the line servos had 100 oz of torque. They were good enough to win with. Now, anything around 150 is plenty. The idea that you need a servo with 300 oz for anything in a buggy is ridiculous. If you really want to spend some extra money go for it, but the servos you have will be fine.

Torque is not something you should be looking for or wanting in a throttle/brake servo, you want speed.

That argument is as old as Ford vs Chevy. It all depends on driver preference. Some drivers prefer a fast servo and some prefer a slower servo with more torque. A faster servo can make the car harder to control on really slick tracks. I personally prefer a slower servo with torque. It helps smooth out throttle respnse.

Also need to remember that your throttle servo also works your brakes. Do you want a 150oz servo struggling and over heating from using brakes? I know I use a lot of brake while racing and the more torque the less I have to worry about a servo failure. But that is just my opinion an something to think about when you find yourself scratching your head why you keep losing throttle servos.

That's not an "argument". I agree it's preference but I'd rather have a fast throttle brake and most racers do. Besides, any fast quality servo will have AMPLE torque and it would not even be a question.

Throttle/brake control from your finger fixes all that.

I like to stay above 250 and less than .12 speed for all my servos. I like my factor of safety to be higher rather than lower . Will a 150 oz servo work? Probably .... But will it likely fail quicker? Probably.

back in the day i ran a 8800S from JR.. which was 105oz at .08... fastest at it time.. i ran 2 in my Revo and they lasted over 5years.. the motor got worn out on both.. that worked great... wasn't in an 1/8 scale... but i'm sure they were no difference back then to now as cars has become lighter.

revo was 9.5 lbs when i raced it

Thank you for all the replys guys.

got_nitro ... I was more concerned with the power to properly stop the car.

I prefer fast servos on all my cars, I am new to nitro though.

Coming from electric I don't think there is a fast enough servo in the world to replicate the throttle response of an electric setup?

nitro is heavier than electric. for nitro its "a must" to have a big torque, makes brake easily and compensate the weight in turn, so you have a consistent feel.

The Savox SC 1258TG is a pretty popular servo & works fine for 1/8 buggy throttle/brake & thats only 166oz-in, speed is .08, something with that torque & speed would be plenty powerful enough for the job.
