Hi! What type of connection is needed to connect the raspberry pi camera to Tower? Would radio telemetry do?
hi, you will need wifi connectivity for video. the telemetry radios are low bandwidth and only good for telemetry data.

Would doing so cost mobile data? Since it connects to the phone's mobile network right?
you will need to establish a wifi hotspot on your raspberrypi and connect to it with your phone or let the pi join a wifi network you are using at home or in the field.you dont need the phones mobile network for this.
