• control box can be removed from motor unit and connected via a 6' cable
• digital direct drive motor - no brushes to wear out, no gears to break down!

The above is a music video shot with a Revolution Motor for the Bolex.
You can see a photo of the setup here on the photos page.

The Revolution breaks down into three parts. The motor pod, the base plate, and the control box.

The motor pod has the motor, the drive coupling, and the motor driver box. The motor pod attaches to the base plate with a thumbscrew.

The control box plugs into the motor driver box, and can either sit on the base plate (attached with two thumbscrews), or it can be used remotely.

Two control box cables are included, one short, and one long.

Backwards running! Backwind the film to your start point, and film another pass

Here we have an external light controlled by the motor.
