TBS Multi-bind is great. I use a Radiomaster TX16S as my daily driver but also have a Tango 2 for when I'm traveling light. Almost all my quads have TBS crossfire and I was excited for multi-bind. It allows you to bind two radios to the same TBS RX so I can grab either my Radiomaster or Tango 2 and my quads work without the need to rebind. It is a bit of work to setup, but the effort is well worth it. I dumped my FrSky so I only use ACCES for some tiny whoops and I'm not familiar with their capabilities around multi-bind.
