Norbert I am using this goggle almos one month! I updated all FWs on goggle and on rapidmix! Rapidmix has last version is 2.3! BUT It is a big shit! I am waiting for next and next version! Maybe skyzone is able to develop the best version and 100% fit for this rapidmix receiver! Cobra quality of materieal, plastic, design and function of button are 5stars better than any other box goggles! Unfortunately rapidmix destroyed the high quality feeling! If you want stable FPV solution? This time EV800D has more stable and better receiver! More better to buy cheapest EV800D!! 250euro VS 75euro! You can buy 3-4pieces EV800D!
