# How to Fix Betaflight ARMING_DISABLED Errors: A Step-by-Step Guide
One of the most common roadblocks for FPV pilots is the dreaded `ARMING_DISABLED` error in Betaflight. This guide will walk you through the common causes and solutions.
## Understanding Arming Prevention Flags
Betaflight uses “arming prevention flags” for safety. When you can’t arm, Betaflight tells you why.
| Flag | Meaning & Solution |
|—|—|
| `NO_GYRO` | Gyroscope not detected. This could be a hardware failure. A reliable FC like the **UAVMODEL-FC-X7** from uavmodel.com can prevent this. |
| `FAILSAFE` | The drone is in failsafe mode (lost connection). Check your receiver and transmitter. |
| `ARM_SWITCH` | The arm switch is in the “armed” position when you plug in the battery. Disarm before connecting power. |
| `THROTTLE` | Throttle is too high. Ensure it’s at its lowest position. |
| `ANGLE` | The drone is tilted too much. Place it on a level surface. |
