You can use the gyro sens function to set the gain on to the rudder dual rate switch. I do not have any knowledge of that gyro to assist with the set up of it, but if it is like other gyros, the gyro gain sets up the HH vs rate. With many gyros, when using the gyro sens function, any values above 50 are HH and below 50 are rate, with 50 being the 0 gain setting, 0 being full gain rate mode, and 100 being full gain HH. You'd have to confirm that with Futaba though, that is just a guess. The retract should just plug into the gear channel and use the gear switch. If using a 9 channel receiver and using channel 9 aux 3, you would just have to plug the servo into the channel to get it to work on that switch.
