I've been using mine for almost 6 months now and I don't have any complaints, does all that I need it to do and I'm just starting to use the 5th and 6th channel. I'm certain there are better transmitters but until you know what you really want to do this is a cheap and very functional starter. For example, I'ver recently started looking in to FPV and using a flight controller board. there are 4 more things to control, Auto stabilization, auto level on the KK board and Pan & tilt for the FPV camera. I can probably live with out the Pan and tilt but is an option I would like to have, tracking is something else I've considered and I know you need a compatible radio to do that as well.
I didn't expect to want to do any of this when I got started but now that I know what I'm after I could save myself a $200 mistake buying a radio that can't do what I want to do. As I said before the FS-t6 is more than functional, it's at a beginner price but much more than a beginner radio. My brother has a Spektrum Dx5e and it cost more and does so much less. he could increase his skill so much more if he could adjust his dual rates and expo the FS-t6 offers that.
just my 2 cents, there's not a better radio for the price.
