Wow, thanks for the tip, I had no idea such a TX existed. $100 is a bit expensive compared to the plane it's supposed to controll, but I really like the idea of one TX to "rule them all".
It does DSMX, (and is cheaper than a similar Spektrum) as well as AFHDS2, (FlySky) and the Eachine protocol for their little indoor stabilised pocket rockets.
I bought mine to make it so that I only needed a single transmitter and I can buy any BNF and know my transmitter will operate it.
For me it is going to be a great boost to what I can buy and fly as well as now being able to test fly any plane I am requested to, (I still teach flying , build for others and help newbies out with setup and test flying).
great times ahead!
have fun!
