Interested to find out what kind of negative people mentioned with Futaba system as well.

Regarding the 4G marketing Futaba pushed out. Im pretty sure it just means the radio it self have cellular connection and has nothing to do with the frequency signal is transmitted from the tx to the rx. This mean the radio is most likely to have an Android system like the spektrum radio, for telemetry, data recording, live updates etc etc...i guess we have to wait and see
