Flight Problems
Stop the flight test, return to propeller-off checks, and diagnose the most likely layer first.

# Symptom guide
| Symptom | Check first |
|---|---|
| Flips immediately | Motor mapping, motor direction, propeller direction, IMU orientation. |
| Attitude goes the wrong way | IMU orientation / axis interpretation. |
| Strong vibration | Damaged propeller, motor, mount, frame rigidity. |
| Fast oscillation | Mechanical vibration, then PID tuning. |
| Drifts or feels biased | Mechanical balance, sensor state, then controlled tuning. |
| Behavior changes with connection loss | Failsafe and active control-session behavior. |
# Return to a safe baseline
STOP AND RESET
If the Drone shows an unexplained control problem, land/disarm, remove propellers, restore a known-good configuration, and re-run the bench test.
