In first line the rudder limits are necessary to prevent the gyro from moving the servo over the mechanical limits and damaging the servo. But when adjusting the limits please note that the optimum throw is not necessarily determined by the maximum possible control travel of the tail pitch slider. '''When the tail mechanics allow a very high range of pitch, it may be advisable to adjust the limits based on the maximum allowed angle of attack of the tail rotor blades.''' Otherwise high tail pitch throw can cause aerodynamic stall of the blades. Such stalls can cause very bad stopping behavior like overshooting of the tail when stopping from rotation and can also cause bad tail response to rudder stick input when performing directional changes. Keep this in mind when adjusting the tail rotor endpoints! Check the helicopter‘s manual to find out how much tail pitch is useful and where to set end points.<br />

In the following of this setup step you will be asked to connect the rudder servo to MICROBEAST ULTRA. When doing so plug the servo connector into CH4 output at the device. Watch out for correct polarity, the black or brown minus wire must be the clostest to the bottom of the device.<br />

In the following of this setup step you will be asked to connect the rudder servo to your BEASTX device. With MICROBEAST PLUS/ULTRA the servo connects to [CH4] output. Watch out for correct polarity, the black or brown minus wire must be the clostest to the bottom of the device. Using NANOBEAST please connect the servo to [CH2] output. Here the servo polarity is similar to SPEKTRUM/Horizon Hobby servos, from inside to outside: signal, minus, plus.<br />

Then attach a servo horn to the rudder servo in such a way that the tail linkage rod forms a 90 degree angle to the servo horn (or as close as possible) and adjust the linkage rod as described in the manual for your helicopter. For most helicopters the tail pitch slider should be centred and the tail rotor blades will then have some positive pitch to compensate for the torque of the main rotor.<br />

This mechanical adjustment especially is important when using the tail gyro in Normal-Rate mode. If the adjustment was not done properly the helicopter will constantly drift to one side or the other on the rudder axis. When using the tail gyro only in HeadingLock mode this adjustment is not so critical. Here the gyro will actively control the rudder so the helicopter does exactly follow the commands of the rudder stick. Anyhow, for optimum performance of the gyro a good mechanical adjustment is essentially!<br />

Using the EasySetup adjustment on the device this setup is separated in two Menu Points. At Menu Point E we set the rudder limits, at Menu Point F we teach the control direction. At first connect the rudder servo to [CH4] port of MICROBEAST ULTRA as described above now.<br />

* Move the rudder stick 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.

'''When the display is inverted (red = right and blue = left) reverse the display (internal control direction) by tapping the aileron(!) stick once.'''

* Optional: When you move the rudder stick to full deflection, the Status LED should light solid, not just flash. If this is not the 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'''. (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.)<br />

{{QUOTE|Always set servo directions in the transmitter first, then check the display on the MICROBEAST ULTRA or in the software and change the internal control direction if it does not match the real direction.

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!<br />

* When you move the rudder stick to full deflection, the Status LED on the MICROBEAST ULTRA 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. Repeat this for the other direction. Note: Do not increase the endpoint too much in the transmitter. We need an exact match of full stick position and stick end position.

This ensures that control range of the radio system matches the internal range of MICROBEAST ULTRA. Later when setting the control style you can adjust how fast your helicopter should turn around the vertical axis. To get reproducable results you have to match your radio to the system!<br />
