I've been flying a Futaba 14SG for over 10 years now and looking at making a move. After looking around I decided to give the FrSky Tandem X18S a try.
I have not seen any drift on mine as of yet. all the newer versions come with Hall Effect gimbals now as well.I really liked the one I played with 2 years ago but that was when they were having the Gimbal drift issue. I looked at getting the Mark II version but got one of those mental blocks that I can't get over due to the Gimbals.
Currently there is no sim like companion however Ethos Suite has indications that it is coming. Suite has made updating the radio and it's components very simple as well as getting custom pictures sized correctly for the radio.I think Frsky is going to release an x20s special edition in red next month and I think I may get it. I was told there is a sim you could use to setup models like the companion app but I can’t find it.
