I don’t have a Taranis, but I did some testing of FrSky FASST receivers along with my other Futaba FASST receivers using my Futaba 12FG. They have worked out well, so recently upgraded my old Futaba 9C with a FrSky telemetry module and FrSky D receivers.
I bought all my FrSky stuff from Aloft Hobbies and I’m very pleased with their service. From my past experience with radio gear, I think the retailer of the equipment can have a huge positive impact on your satisfaction with your radio. Aloft Hobbies makes it a great experience.
