THE ARMING DIAGNOSTIC / BETAFLIGHT
A warning is
a useful starting point.
Find your arming-disable flag, then follow the relevant official check. This tool covers common Betaflight flags; names and behavior can vary with firmware.
Start with the props off.
Remove propellers before bench work. Do not bypass arming protections. With the aircraft connected to Betaflight Configurator, the read-only CLI command status can show arming-disable flags. The connection itself can add flags.
YOUR NEXT CHECK
Read the flag before changing a setting.
Choose a flag to see a focused starting point. If several flags appear, record all of them; resolving one may leave another active.
Keep the diagnosis specific.
Record your flight controller, firmware version, receiver, exact flag, and the circumstances. Stop if you see unexpected motor movement, damaged wiring, or uncertain power connections. The flag guide helps you find documentation; it does not verify that an aircraft is safe to fly.
