Telemetry

Telemetry - Allows you to see information about the drone on the remote, by making two-way communication between the remote and the receiver.

Frankly, for someone who will fly with glasses, it is not important to see the distance, position, battery status on the remote, but if there is, why not use such a feature...

Unfortunately, you chose the wrong controller brand for the racing FPV drone I also made. However, I can say that it is a very good control system if you are going to use it for imaging or helicopter or airplane purposes.

I'm thinking of buying a second control system Frsky X9D, as I've spent a lot of time with this control system and now I'm nervous. Do it with SMart port, telemetry etc. go late..
