Spirit System

Hi, i read the manual but i am not sure which cable i really need for the most simple solution...

I have a spirit black edition, an frsky x4r receiver, a hobbywing V4 60A, and i want to have the telemetry of the Voltage of my lipo.

I think i only need the integration cable... is it true? or should i need the the telem uni cable too?

Thks.

Oups... sorry it is in bad section the question is for spirit heli not aero...

You can use external port of the receiver for measuring battery voltage. But you will need a voltage divider as the max voltage is limited.

Or if you want full Telemetry and Integration with Taranis, you will need FrSky integration cable and Telem UNI cable.
