No worries, @PJC! My apologies for adding confusion!
That’s quite wild! With no screen and an app, it sounds similar in concept to the Spektrum DXe. Just a lot smaller, and thus better for kids and travel. On a FU-RC related note, I realized that the casing looks very similar to a stock Syma controller (which I stumbled across this morning).
In my mind it’s really a double gateway. With the multi-protocol capability, you can access the world of FrSky, yet continue to fly DSMX without worry. IMO, that’s particularly valuable in a compact TX. Because when you travel, you don’t want to carry a second TX for a different protocol.
I suspect that I will eventually add a dedicated, full-size FrSky TX to my toolbox. However, my expectation is that I’ll keep around a full-size DSMX TX as well, if for nothing else than out-of-box compatibility and easiest setup with the fleet of Horizon/E-flite BNF toys, e.g. my UMX Radian (micro electric glider) and upcoming UMX Timber (micro BL bush plane).
