Crash
If Solo recovers GPS during flight, Solo switches from Fly:Manual to standard flight (Fly), and GPS positioning
activates. The following displays show (from left to right) the "GPS lost" alert, Solo in Fly:Manual, and "GPS
recovered" alert. For optimal GPS signal strength, always choose a location with a clear view of the sky. Press

7.2.6 Controller Battery Alerts
When the controller battery level reaches 10%, the controller displays an alert to notify you to charge the controller
at your next opportunity. At 5%, the controller prompts you to end your flight and charge the controller. If the
controller battery reaches a critical level in flight, Solo initiates Return Home. The following displays show (left to
