Get a Taranis, and let the woman talk to you. She'll tell you all that stuff. You can even plug in headphones if you want to. My poor eyes have gotten so bad, I can't even see the little LED screen on most transmitters, without reading glasses, then have to take them back off, to see my quad, line of sight. Pain in the arse. Also have some Head Play, and one of the HK cheepee goggles, can't get either in focus enough to see right. Skyzones and Fatsharks still working for me, but I dunno for how long. Old age sucks! (66).
