Hi all... I have a Vaterra Ford Fiesta RallyCross, equipped with a Spektrum SRS4200 transmitter with a Spektrum DX2E SPM2320 radio.

How can I add telemetry to my car such as signal strength, receiver voltage, temperature, speed etc? Do I need to change the radio to receive these data? I see that in my transmitter there's a "data" slot. Is there something that I can plug here and can use to transmit to an iPhone or save data?

thanks.
