To configure Falco the easiest way is via your goggles or FPV monitor. However, if you have an old non-osd board or what ever other reason you can use the Falco Companion to run the setup and change features. The Companion runs on the computer and you use your RC transmitter to navigate the menus. To initially install FalcoX plug your board into the computer and then open the configurator linked below and click, update. Once it is complete power the ship and turn on the radio. Make sure you have the receiver bound to the radio, or the setup will not work.
The configurator can be found at this link.
