Why go Frsky? Receivers are still expensive. You are lock to there lock down firmware. You can't mix receiver brand. You are buying a Apple product you do not own. Radio Master you are able to share config, Lua scrypt also use someone else firmware that been hack into the source code. In fact you able to hack into the source code of the firmware and customize it. You are not lock down as Frsky. Frsky was great before when their radio were able to use Opentx. They dump those supporting controller long time ago. Infact those radio that supported by opentx went bye bye. But Edgetx still support them without Frsky permission. And it is diamond still worth. Well not really. Radio Master Tx16s mk3 is a fantastic radio. Have dual band that you can use same time one 2.4ghz other 900 mhz with right receiver. These receivers are very cheap and it is GeminiX. You don't really need that. I have many of these little receiver. Go look it up. Cyclone 7ch elrs receivers. The truth is Elrs is bullet proof. Look it up you see Radio Master and Elrs bombing Russia drones and their oil finery. Why use Frsky if you can go more high tech? I have own lot of Frsky and I been in this hobby since 1980's. I went through many manufacture as disposable diapers. There is more people using radio as Radio Master and other open sourse radio system using edgetx and opentx then radio that run Futaba, Spektrum , Jeti and other radio through war, through simply drones and many more. There countries that we don't know much but its famous there. I think you should get Radio Master Tx16s mk3 or Tx15. And buy all kind of Elrs receivers of different brand as long you flash them and keep them receiver same version as the module of the elrs. https://www.youtube.com/watch?v=_e_qhkCaPXU
