RE: Let's talk about servos - Whatever is on your mind
As a General guide for such designations. These would be approximate strength I would use for torque for these designations
Standard Servo - 40 ounce/inch - Example, Hitec HS-311
Mini Servo - 25 ounce/inch - GWS Naro Max BB
Micro servo - 15 ounce/inch - Hitec HS-55/65
Sub micro servo - 7 ounce/inch - GWS Pico servo
These are not industry standards, they are my own interpertation of what these terms would mean in terms of servo strength.
