Setup with StudioXm

1. When you move the rudder stick to full deflection, the Status LED of the AR7210BX should light solid and the label right or left should change the color accordingly. If the stick is not moving far enough, you will see the message "Increase!" In this case increase the servo throw/endpoint of the rudder channel in the transmitter just as far so that the Status LED changes from flashing to solid when the rudder stick reaches the end position and the label will disappear in the software. (Note: Do not increase the endpoint too much in the transmitter. We need an exact match of full stick position and stick end position. So the Status LED should just change from flashing to solid when raching the end position.)
2. Now connect the rudder servo to [CH4] port of AR7210BX as described above and check the rudder direction on the helicopter. If the stick is moving the servo into the wrong direction use the servo reverse function of your transmitter and reverse the rudder channel to set stick control direction correctly. Now when the servo is moving correctly set the rudder direction of the AR7210BX gyro: When you move the rudder stick/servo to the right, the Status LED must light up or flash in blue color. When you move the rudder stick to the left, the Status LED must light up or flash in red color. When the display is inverted (red = right and blue = left), reverse the display (internal control direction) by choosing either normal or inverted in the software.
3. Finally adjust the servo limit by changing the values in the two adjustment boxes for each direction. To do so, carefully use the rudder stick to move the servo to the endpoint (watch out to not jam the servo) and increase/decrease the endpoint as necessary.
Always set servo direction in the transmitter first, then check the display of the AR7210BX or in the app and change the internal control direction if it does not match the real direction. Do not change the internal direction in order to change the servo direction! This is only used for telling the gyro in which direction it must move the servo. Be very conscientious when doing this setup step, as wrong gyro direction will cause loss of control during takeoff and you probably crash the helicopter!
In addition you can check the gyro direction by turning the helicopter by hand around its vertical axis. When turning the heli the gyro must move the servo so that the rotor will produce a counter action agains the turn direction. So later in flight the gyro will stop the helicopter from unwanted movement.
