==== No USB Connection / FC not recognized ====
  * Make sure the LED's on your flight controller light up once you plug the USB cable in
  * Check the USB port for damage, dirt or coating that prevents connection
  * When using USB-C to USB-C or USB-C to microUSB cable, try to use USB-A to USB-C or USB-A to microUSB cable
  * Install the correct drivers using the ImpulseRC driver fixer
  * Make sure you have no short on your FC and the polarity of all soldered devices is correct
  * If only one red led lights up, the FC is in DFU mode. Try to reconnect the cable

==== Enter DFU Mode ====
  * In the newer Betaflight Configurators you can access DFU mode by pressing the Button "Activate Boot Loader / DFU" in the setup tab
  * Else you can write dfu into the CLI and confirm by pressing enter
  * Also you can press the boot button while plugin in your USB cable to the fc
  * Once in DFU mode the red led of the FC should light up solid and Betaflight Configurator recognizes the FC in DFU mode
  * If that is not the case install the correct drivers with the ImpulseRC driver fixer


==== I can not arm my quad ====
  * There are a lot of things that can prevent a quad from arming
  * First remove the propellers and or use a smoke stopper
  * Plug in the usb cable and connect to betaflight
  * Power on your transmitter that should already be bound to your RX
  * Power up your quad using a power supply or matching LiPo battery
  * Now go to the setup tab in Betaflight configurator and try to arm your quad using the assigned arm switch
  * You now should see some "Arming disabled flags" pop up in the info section at the right side of your screen.

  * Proceed here if you don't see any arming flags
  * Check if you get any receiver input --> Section Receiver
  * Check if your modes are set correct --> Section Modes


  * Proceed here if you see any arming flags
  * Remember the Arming Disable Flag that you are getting and have a look at this table [[https://betaflight.com/docs/wiki/guides/current/arming-sequence-and-safety#description-of-arming-prevention-flags|Arming Disable Flags]]





==== I get no receiver input ====
  * Make sure your transmitter is powered on
  * Make sure your receiver is powered on. Depending on the model you have to power up your quad and usb power is not enough to power the receiver.
  * Make sure your transmitter is bound to your receiver.
  * Check that the output map of your receiver matches your desired link protocol and wiring.
  * Check the wiring on your FC. For this look up a pinout of your receiver and FC. Make sure RX and TX are crossed. So receiver RX --> FC TX and receiver TX --> FC TX. Also remember the UART number of this port.
  * Go into the ports tab in the Betaflight Configurator and make sure you select "Serial RX" on the port you solderd your RX on.
  * To check connection go to the "Receiver Tab" in Betaflight configurator and see if the bars move with your input.
  * Make sure to select the correct Receiver Mode and Serial Receiver Provider for your receiver. Most new receivers use Serial and CRSF.
