This the standard Revolution 121 motor attached to a Mitchell NC. It is specially 'tuned' for the Mitchell, because the Mitchell has a giant brass flywheel in it. Also, it is capable of reverse operation, because Mitchell cameras will happily run in reverse.
It has all the features of the Revolution Motor
Shutter speeds of 1/8, 1/4, 3/8, 1/2 second, and
Long-duration exposures from 1 second to 4 minutes.
Intervals from 1 second to 9 hours.
Auto-shutoff after desired number of frames exposed!
Delay-before-filming up to 24 hours.
Presets! Store favorite settings in permanent memory.
Chaining! Film the contents of multiple Presets.
It will also run at slow-sync speeds (maximum speed is dependent on voltage, but it generally at least 4fps and up to 8fps).
