The HERCULES X4 UA is controlled by semi-automatic flight modes accessible to the operator, such as:
- Altitude Hold
- Loiter GPS
Assisted Flight Modes
When using these assisted flight modes, it is crucial for the operator to have a clear indication of the position and heading of the UA.
To achieve this, the HERCULES X4 drone is equipped with:
- 
Strobe Flash White LED - Helps in spotting the UA midair.
 
- 
Navigation LED Lights - Green LEDs: Indicate the front of the UA.
- Red LEDs: Indicate the rear of the UA, helping to determine its direction.
