Digital servos

[kroony]

Hi all,
Just wondering a few things about the digital servos. From what I have heared, they are much smoother and have beter position control etc. Is that right?

Also, using the extra pulse width that the SSC-32 can provide, will the digital servos give 180 degree rotaion like the analogue servos?

I’m just wondering if it’s worth getting digital servos like the 5645’s instead of analogue like the standard 645 servos. And is there much of a benefit getting HSR-5990TG over a HS-5955TG as I would only run them at 6v anyway? Any help, or experiences with differences would be great.

Thanks

Edit: I found that they are capable of 140 degree rotation. But now wanted to ask if the HS-5955TG comes with a round servo horn like the other ones, as it is only pictured with the arm.

The Hitec digital servos can be opened up to 180 degrees using the programmer.

All of the digital servos perform much better than analog servos. The digital servos respond to a pulse range of 1100us to 1900uS. The 5955 is really considered a car servo. So it’s range is 140° until you change the end stops with the servo programmer. The 5990 on the other hand is a robot servo and has the 180° right out of the box. It also has position, current, and voltage data feedback. It will also shut down if it heats up too much, therefore saving its own life. Some applications may do better with digital servos. Bipeds of course, and arms if you’re wanting to lift heavier objects. I have not seen the need for digital servos in hexapods though. We include round servo horns for any Hitec servo that does not come with them. We also have aluminum ones available separately.
