Torque or Speed

[serpent 973]

I always thought that a high torque servo is for steering and a high speed servo is for throttle is this right?

Ralph Burch from team Serpent uses high torque for both his steering and throttle........so do I!

Most servos have both torque and speed. You really want both because steering want torque and speed to move the wheels, throttle to move it fast, and strong to apply brake.

serpent, generally speaking you are correct, but it depends on the situation. To have super high torque you will sacrifice some speed and vice versa. If the vehicle or the rims/tires are large and heavier, like on a monster truck, more steering torque is a big plus, but I personally wouldn't run that same servo on the throttle because it would produce a slower throttle response (but don't forget, you still need enough torque to pull the brake too). There are some servos in the middle ground with a decent amount of torque and respectible speed. With those you could run the same servo in both spots if you wanted to. On my off road cars (buggy and monster truck) I am running higher torque on the steering and higher speed on my throttle. On my on road car (super nitro) I went with the same 'middle ground' servo for both. This setup works great for me. Good Luck

Hey guys,
I plan on running a servo dedicated to disc break on a custom vehicle. I was wondering what a good amount of torque woud be for that servo. The car will weigh a little more than a nitro tc3

Thanks,

It depends on how you are going to operate the brake, I guess. If it's a "cam-type" like most nitro brakes, where the rod rotates against two plates and gives a little squeeze that is more than enough to stop the disc, even a standard servo would suffice. If the servo is going to do the actual squeezing in some way and function like an actual brake caliper, you may want to go to a higher torque, but an 89 oz/in should be sufficient.
