What a lovely unit! Much lighter and more comfortable in the hands than the X12S, and with an all-new OS called EthOS, FRSky have gotten everything right with this I feel.
I flew a couple of smaller models with it at the weekend's PSSA meet, and everything worked as expected. I think I'll be programming some of the larger fleet into this one shortly, as the new Tandem receiver line and the more recent ACCESS receivers are very capable and make the most out of the radio's capabilities.
Only thing missing at the moment that I really want is a a tray adaptor, so I can secure it to my harness. I find the stability the harness provides a game changer, especially for a solo slope pilot when launching.
