• 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

• 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

• 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 Arming Disable Flags

• 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.
