Power 1501 Mg Servos

Can anyone tell me if these are continuous rotation servos?

They will only rotate 165 degrees according to the datasheet.

Thanks for the quick reply

You can modify them to be continuous though , it is fairly simple.

Unscrew the case , find the big pin on the main gear. Use a dremel to cut it off smooth to the gear. Put the top of the servo back together. Then the next step involves soldering a resistor in the bottom...

Ok, I have the pin removed. Where/how do I solder the resistor?

Here is one way which turns a servo into a gear motor but then must be powered by an h bridge....

This is the most common version of a servo mod and it utilizes the original controller to power the servo without an external h bridge like the first mod i showed you.



Lastly there is a version where the potentiometer in the servo shaft is cut , then you position the pot into the dead center known as dead band and glue it in place.

Also, you can be modified continues servos directly from Servocity.com. I highly
recommend them as one of the best places to get a nice mix of servos ar decent prices and always in stock.
