I have just gone through the same process, DX6i user for a couple of years - no problem with it but the dollar rate is so good at the mo I thought time to to future proof!
Agonised over spending that much on something that doesn't actually fly?
Obvious choice was DX8 but the more I looked the more glitches, recalls and strange happenings are apperent on every forum! Anyway other options - JR too expensive, Futaba seem to keep changing their mind about operating system & confusing (FASST, FHSS &GDNOWS). Oh DX8 no glider setup.
Then looked at Hitec - nothing bad on any forum I could find, High spec more than I need, good price. So what if I have to buy a few new rcvrs off to the States in a month so that will fix that.
Hopefully I have made a good (right) choice time will tell.
TH were the cheapest so have pushed the button. Hopefully it will arrive before I go Statesideor my wife will findout!!!!
