Testing servo torque

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.

Thank you for your help. Joe
