This is a launch pad for micro quad copters, such as Tiny Whoops.

If using on a slick surface, I recommend using anti-slip foam pad, such as you would for securing a lipo to a 5" mini quad or else it will slip easily.

I also recommend adding a thin line of hotglue to the lip (see photo) if you have issues with your micro falling off of the pad. I noticed this is more common when used on a slick surface, likely because carpet breaks up the propwash a bit
