FlightZoomer Companion 3 is the standard airborne part of FlightZoomer.
It runs on a smartphone which is attached to an RC aircraft or multicopter. The apps both transmits and receives data to and from the FlightZoomer Cockpit app.
This app differs from the FlightZoomer Sensorics app in that it not need a FlightZoomer relay server as intermediary agent to connect with the Cockpit app.
