As you probably already know, the Jumper T18 has a built-in multi-protocol module that supports R9, DSM2/X, FrSKY, SFHSS, FlySky, FlySky AFHDS2A and more. Since your drone is the Taycan25, you probably don't need anything long range. Many FrSky receivers other than older stock are shipping with ACCESS protocols loaded and the FrSky firmware is a bit of a mess with all the versions and compatibility issues right now, so I'd probably avoid them. Basically it boils down to what ecosystem you wantto buy into. You could use one of the supported protocols in the Multi-protocol module, or go and buy into TBS crossfire, Tracer or Immersion RC Ghost... all of which need an external TX module, but offer a more mature ecosystem and a rock solid control link with great range. They will all do the job.
