Default JR 3021 and 3121 servos

What is the difference between a 3021 and 3121 ?? Is the 3021 coreless like the 3121 ?. Is there any problem using either servo with 6 volts ( 5 cell Nicad ) unregulated ?? Looking to use either servo for throttle on my new pattern plane. Thanks....Ed.

They are both coreless and both would be fine on a 6 volt pack.
