Hi Adrien, the cforce mini RF can be used as an AUX motor, which would allow you to motorise any other filter in a similar way. AUX mode can be used when the ALEXA 35 is the motor controller or the cforce mini RF is acting as a radio host. Control is available from the Hi-5 or ZMU-4 in a similar way to the Cinefade in VariND or Rota Pola mode. It's also possible to use both the Cinefade and an AUX motor simultaneously for 5-channel control.
