This is my first build and I have the new Pixhawk Mini, the Taranis Pro and an X8R receiver on a QAV400.
With this setup the only telemetry I have available on Taranis at this point (with no sensors) are the signal strength (RSSI) and the controller's voltage. Now from what I read I gathered that in order to have more variables, like, quad voltage, current etc. I need to add sensors on the quad. I have two questions in this regards:
1) What are the typical sensors mounted on a quad that is intended for general flying and maybe some video capture? For example is current and GPS data really important on the RC itself? I can always monitor this data on a ground station via a USB telemetry module, no?
2) Given that some of this data, for example GPS data is already available in PixHawk, isn't there a clean and easy way of how to pass this data from PixHawk to my X8R and to my Taranis? Why do people buy sesnors and replicate what's already available in the micro-controller itself?
I'm new to all this but I'm trying to learn. Thanks.
