I was wondering abuut which reciever, if any, that I should get for my Diatone Crusader Gt2 200. I am getting a Frsky Taranis x9D plus transmitter. I am also getting the Fatshark Diversity reciever for the Fatshark Dominator v3. Ut I noticed in some videos that A transmiter reciever is needed. Which options do I have and which ones are the best??
