Testing servo torque

[Espeefan]

If you've got some older servos, you might not find the specs online. In that case, you might have no choice but to test the torque yourself. I think the standard for measureing the torque is to use an arm that hooks to your strain gauge exactly 1" away from the center of the output shaft.

What's a good torque strength? That depends on what you want to use the servo for. For shifting a transmission, you don't need much. Just about any standard servo will handle that job. Even the cheapest ones can do it without a struggle. For steering, you'll need a little more torque.
