Screw hole size Herelink Controller

Dear all,

I have issues finding the right screw size to mount the herelink controller on a custom made mount. The screw hole is located on the bottom just below the physical buttons. I have tried M6, which goes in a little but not far enough. Anyone have experience with this?

Kind regards,

Kevin

I am not sure there are official mounting screw holes in the case, maybe somewhere here Herelink Overview | CubePilot

What do you mean with official mounting screw hole? The RC controller has officially a hole for a screw mount. I checked already the herelink overview, there is nothing about this on that page.
