I got My ARCL to work, and it works just fine. I used a Motorola Radius P200 Low-Band handheld radio to trigger it. Here's a link to my video of it running.
It will run fine on 120V. The way the control panel was set up, you could adjust the voltage to the chopper from 120-240 volts. The higher the voltage, the higher the pitch.
^I agree 100% with Justin.^ You can see the mechanism and motor for the rotator system. All 5 here in Phoenix are the same kind as that one-40 horse 10/10 port rotating model.
