Xtra.Emergency STOP Button

With this emergency stop button, everybody can immediately intervene from the sidelines in case of an emergency.

With one press of the button, all the quads are immediately slowed down and brought to a standstill. This is done via the signal received by the transponder.

For even more safety and a greater range, the installation of several emergency stop buttons is also possible .

The command sent by the emergency stop button is repeated by every installed button until the button is reset.
