The mounting plate that came with the RSC 2 is less stable than I would like. It comes off too easily and is mostly plastic. It was the perfect replacement. While DJI says the RSC will accept 2 ARCA panels, none of mine will fit. But this one... is like a glove. And since my camera is in a cage with multiple 1/4" mounting holes on the bottom, I can attach this plate with a couple of screws (included!) for added stability and security. It is durable and very reliable.
