Follow Focus Servo RIG

I needed a remote control system, both for the focus (follow focus) and for the zoom movement on different lenses mounted on the Z-CAM E2.
I tried to make it as economical as possible, by adopting two powerful mini servos, all connected to a receiver that will control a large gimbal.
The whole thing is mounted on 15mm SMALL RIG.
For the remote control it is possible to use a simple 2 channels, or as I intend to build a more complete programmable 10 channels, recycling a TURNIGY I10, the latter will be used both for the gimbal and for the remote controls of the lenses and the Z- CAM E2.
An O-ring must be mounted on the circumference of the wheel, which will come into contact with the lens.
