This is a simple cover to protect the M-1 Volt’s pan encoder ring.

The magnetic material of the encoder ring is pretty soft and I’ve found that it’s really easy to catch it on the docking fork and damage it when you’re docking/undocking.

This is especially true when you’re flying a heavy package and the gimbal is pretty high up on the post.

This ring just slides over the post and sits on top of the Volt. It can either be left free to slide up and down with the gimbal or you can fix it to the Volt (double-sided tape is probably best).
