Hello service team ,
my Brain 2 is suddenly sensitive to knocking.
see video what could it be?
From the video it seems that the blows given on the connectors cause false contacts in the connectors themselves and this can be normal. For this reason it is good practice in modeling (heli, airplanes, boats, etc.), to attach the connectors to the cases of the control units and receivers (applies to all brands) with hot glue so that if you move the control unit the connectors move together and vice versa if you move the connector the control unit move together.
The use of hot glue is recommended because it is then easy to remove in case it needs to be done for maintenance or component replacement.
If the phenomenon occurs with very slight and light taps, it would be helpful to identify which of the connectors has wide internal female contacts or has a wire crimped badly to the connector (stuck on the outer plastic of the wire but not making good contact with the internal copper wires). To do this, one would have to move the various connector leads one at a time with tweezers to see which is causing the problem.
