2.9 Rebuilding of the C2 Link

To ensure the safety and controllability of flight behavior, the EVO Lite Enterprise Series multi-rotor drone will continuously attempt to reestablish the C2 link with the RC after losing the C2 link. In practice, this process is divided into the following stages: PDF p. 31

When the aircraft is disconnected from the remote controller, if the connection can be restored within 5 seconds, the remote controller will automatically regain control of the aircraft. PDF p. 31

If the link is not restored within 5 seconds, the flight application will display a warning saying “Aircraft disconnected.”, and the aircraft will automatically execute relevant flight control actions according to the set lost action. PDF p. 31

During the execution of a lost action, the aircraft will continue its attempts to restore the C2 link. When the aircraft successfully restores the C2 link with the remote controller, the remote controller still cannot control the flight of the aircraft. To make the remote controller regain control of the aircraft, you must press and hold the pause button illustrated on the remote controller for 2 seconds or pull the pitch stick to exit the lost action.

Original instruction with its control symbol

During the flight, as long as the aircraft and RC can communicate normally, the C2 link will be maintained continuously. PDF p. 31

If decoding errors persist for a certain duration, leading to communication failure, the C2 link will be disconnected, and the aircraft will enter a reconnecting state. PDF p. 31

Signal lost action of the aircraft includes RTH, Hover and Landing. PDF p. 31

After losing the C2 link, the RC will display "Remote controller and the aircraft disconnected" warning message (in red) in the status notification bar of the flight application with a corresponding verbal warning. PDF p. 31
