I've been thinking about purchasing the new fatshark HD goggles when they become available. I currently have the DJI 5.8 MHZ transmitter/receiver http://www.bhphotovideo.com/c/product/998680-REG/dji_cp_al_000001_5_8gzhz_video_kit.html Will the goggles be compatible? Does anyone know what all would be needed to make them work with my phantom 2? I'm guessing: Goggles Antenna 5.8mhz receiver battery diopter (bad eyes) Thanks in advance for your help. One more question - what is the "Head Tracker" and how does it work?
