Review on Spektrum TX USB Programming Cable by Jose Muenzen

The latest 2021 update of the WIN program supposedly made it compatible with the new AR637T receiver which was designed for 'direct programming' from the transmitter. Despite the connection, however, it did not show any function. But to make matters worse, it behaved stupidly for old receivers like the AR636, which I previously successfully programmed. So I had to downgrade the software to an earlier version. Similar bad experience with my DX9 transmitter. I had to update the firmware to be able to "program directly" on the AR637. It worked. However, when I selected an older model with the AR7350 telemetry receiver, the transmitter found no telemetry data. What a failure. My advice to Spektrum: slow down the development of new things and apply better quality control.
