TBS Tango 2 Module Bay Add-on for ExpressLRS or Multiprotocol (elegant solution) 

Thanks man, I'm glad you like it :)

For multiprotocol I recommend TBS because it's very good quality. When you need ELRS then I bought HappyModel ExpressLRS 2.4GHz ES24TX Slim Pro TX. It works great and quality is nice.

Multiprotocol Module can't handle ELRS as far as I know. If you want ELRS in your tango 2 module bay addon you can buy BetaFPV ELRS Nano TX Module. As far as I can see on their official product page it supports tango 2. My only concern is the BetaFPV quality - it's very random to be honest. I would ask TBS via email if they have any plans to produce their own ELRS ;)

UPDATE after 7 months :P - I bought HappyModel ExpressLRS 2.4GHz ES24TX Slim Pro TX. It works like a harm with my Mobula 7 ELRS 1S and Tango 2 module bay add-on. If I'm not wrong even the ELRS developers suggests the HappyModel's module.

​@@rfly-fpvhi, what firmware version is Tango 2 on? I mean Freedom TX and Crsf version.

​@@SammyFiI just checked in TBS Agent Web: Freedom TX is on 2022-03-18 v1.34 and XF is on 2022-12-15 v6.19

@@rfly-fpv thx, but have you tested on older versions, 1.29 & 4.11?
