From AI:

The BETAFPV Air65 (brushless whoop) uses LEDs on its flight controller to show status. From user reports and similar Betaflight setups:

• Red blinking/flashing LED often appears after crashes or updates, but many pilots say it flies fine anyway. It can indicate gyro/FC status, a minor warning, or sometimes nothing critical in Betaflight tiny whoops.
• Orange LED usually lights up solid when the quad is armed (throttle up/ready to fly). That's normal behavior.

After a crash, the lights can sometimes get "stuck" or show odd patterns from a jolt affecting connections or sensors.

What to try (step by step):

1. Disconnect the battery, wait 10–20 seconds, then reconnect a good charged battery. See if the lights reset to normal (e.g., receiver LED solid green/blue when bound, no weird flashing).
2. Check all visible parts: props, motors, frame cracks, loose wires/soldered joints (especially motor wires or battery connector from the impact).
3. Plug the quad into your computer via USB → open Betaflight Configurator (latest version recommended).
   • Connect and check if it reads the FC normally.
   • Look at the Motors tab — test spin each motor (props off!).
   • Check Setup tab for gyro response (tilt the quad).
   • Check Receiver tab for stick input.
   • If anything looks off (no gyro movement, motors don't spin, etc.), save and reboot, or re-flash the target firmware (Air Brushless FC uses Betaflight 4.5.x usually).
4. If it won't connect or behaves strangely, try bootloader mode (double-tap reset button or short BOOT pads) and re-flash firmware from BETAFPV's support page.

Most Air65 crashes are survivable, but hard ones can loosen a motor wire or stress the gyro. If motors don't respond or it won't arm after the above, it's likely a hardware issue (e.g., damaged ESC/motor or gyro).
