    HCS Compatible.

    HCS (High speed Communcation System) is the new high speed communication system between the receiver to the servo. The HCS mode shortens communication time of the signal which is compressed. HCS compatible servos is changing mode automatically by signal from receiver. So HCS compatible servos can use with all receivers.
