If you have the Fly more combo or purchased the ND filter set separately, do the back of the filters have 2 magnetic sensor looking spots? I noticed this when I pulled the camera filter frame off. No effect in the Fly app to detect if its off or on but curious if the ND filter set has these too.

Yes, the filters that came with the fly more kit have that "metal" spot. It is a "wear point" . The spring loaded projection sits in that to hold it in place once twisted on

Thanks! I figured it was a wear point to keep it on.
