Review on Spektrum TX USB Programming Cable by Tim Knoepfle

The cable allowed me to get a serial number to register my As3x RX in my Blade 230s. That's all he did. My software is up to date, so there have been no updates since 07/06/16. The software is 4.23 and is the latest for now. I wish I knew this before spending money on a cable but you can't tell what the latest software is on the spectrum website without registering an RX and you can't register an RX without a serial number and you can no serial number received number without cable. A sneaky way to make more money from parts you may never need.
