The control element is a simple 10K potentiometer. The fully assembled and tested unit comes with servo lead and potentiometer fitted. The unit simply plugs into the servo lead on any channel on which fail-safe is required. One unit is required for each channel. Approximately one half of a second after the input signal is disrupted the servo will drive to a predetermined position, set by the fail position pot in the FS-2 module.
Most common application is for a fail-safe throttle.
Operation is very simple. Just plug the servo plug into the channel required to be converted to Fail-Safe operation. Plug the appropriate servo into the socket on the Fail-Safe module. The servo will take up the FAIL position after about a one half second delay. Simply plug in the MX-2 between the receiver and servos and instant mixing is available on any two channels.
