Application(s): industrial delta robot for educational purposes

Comments: Used with PC application in C# controlling the servo by an SD20 servo controller and i2c/USB from Robot Electronics UK
- Powerful low priced servo.
- The accuracy could be better for this application. Very small steps are not executed but delayed to a larger step.
- High surge current of 3 Amps and up.
- A bit noisy unsubtle movement

Comments: These are brilliant servos with fantastic speeds and tourqe for the money. I have been using them for a few years.
The only downside i have found is the plastic mounting lugs can crack if you over tighten the servo mount screw but this is rare.
