I am a happy Spektrum DX9 user and probably would not change, but I am totally impressed with the Taranis specs especially for the sub $200 price.
Is it as good as it appears to be on paper?
I also have a T9x which for an entry priced tx does really well.
The Taranis is not just streets ahead, it is whole continents ahead.
I don't have any idea of the capabilities of some of the higher end TXs and I am still learning what the Taranis can do.
The OpenTX firmware along with the Frsky hardware make for one powerful and very capable tx.
So many customisable switches, dials and functions, although at the cost of time to learn the program.
I have yet to discover it's full capabilities, in fact it is probably capable of way more than I will ever need.
Needless to say I am very happy with my purchase.
