Hello Matthias, further tests have shown the following: my old configuration Radiomaster TX16S radio with EdgeTx and with the old FrSky XSR receiver and S.Port sensors (FrSky MLVSS, SM Unisens-E) works again with the Spirit Pro when I downgrade the Spirit Pro to v3.6.2. Integration and telemetry work, but you have to disconnect the S.Port sensors when working with the LUA script. However, I won't be going down this route with the S.Port any more, as I can't use the new FrSky TW mini receiver with the TX16S anyway, but only with my new FrSky Tandem X20 Pro AW. This means that I will go down the FBUS route, but unfortunately I will also have to remove my two FrSky MLVSS and SM Unisens-E sensors from the helicopter (an older TRex 600). I'm replacing them with FBUS-compatible sensors from FrSky, a FLVS ADV, a Vari ADV and a VFAS100, all of which have already been ordered. I hope that with the Spirit GT everything will work as usual again. The next “construction site” will be my largest helicopter, a TRex 800 Pro DFC, in which I currently have a Spirit 2 installed, I will also convert everything there to FBUS, as I will also install a FrSky TW mini receiver there. I will report further

.
Best regards, Erwin
