The Anatomy of a Vortex
Connectors and Switches
1) USB connector ​ , used to configure the flight controller and upgrade the Vortex
firmware.
Note that to use the USB connector, a battery must be connected also. The Vortex
cannot be powered through the USB connector.
Please be careful not to put too much strain on this connector. It is a lightweight
surface-mount part, and if the quad is dragged around by the USB cord it may not
survive.

a spektrum receiver in bind mode.
Press and release after 1st beep to change video band, release after 2nd beep to
