You can look at servo torque all day on paper, but we thought we'd give you a visual understanding what some of those specs end up looking like compared to other servos side by side.

Fun video. I am assuming there is not, but is there a standard employed across different brands in length of moment for gauging these specs?

Well assuming you did not sleep through math and science classes, if you even bothered to take classes, use 12:1 to visualize.

Foot Pounds is easier to visualize. It takes 12 inch-ounces to equal 1 ft-lb. So if that servo arm is 1 foot long 12 inch pounds will lift 1 pound.

Cool video though.

12 oz in is .0625 ft lbs

So lets say with 44oz-in servos I can expect 44oz at 1 inch from the rotational axis, perpendicular to the arm?

You are right, had a brain fart of inch pounds to foot pounds. Left a step out of factoring out 16 ounces. My bad. That is why I am an electrical engineer and not mechanical.

Hell, I'm a journeyman machinist and just learned that. Don't tell my peers.

Well heck lets make a deal. You delete your post, and I will delete my post.

lol nah, this post made my morning.
