Steering Servo: How much torque is enough?
Hey fellas!
So I saw this video the other day where a guy has this jig set up with a scale and an amp meter and he tests several servos to see if they meet the advertised specs. One of the servos he tested pulled 559.5 oz-in at 5.7 volts but it drew 7.28 amps! It got me thinking though how much is too much, 559 seems like way overkill. And most ESCs only have a 2amp or so BEC built in. So I guess what I was thinking is how much torque do you really need for the various applications? Maybe some of you with more knowledge and experience than me could chime in with your opinions. For example how much torque for a 4wd short course truck or a touring car or a rock crawler. I think it would be nice just to get the information out on a thread so down the road if someone tries doing a Google search (like I did before posting this thread) they will be able to have a good reference. Cause servos are expensive. Thanks guys.
