To enter one of the menus you have to wait until the unit did perform the self test and did fully initialize: The Status LED must get blue or purple and the cycling LEDs A to G and H to N must have stopped.

Factory reset only can be performed when being within Setup menu. So you have at least to get to Setup menu point A (or later), release the button and then push it and keep it pushed for at least 10 seconds. Note that factory reset will only revert all parameters of parameter menu and setup menu to default. It has no influence on receiver menu parameters. If the unit does not initialize due to wrong receiver setting the factory reset will not help. In such case also have a look here.

===Selection in the menus with the rudder control stick does not work.===
 +
Maybe there is not enough movement or any movement at all on the rudder channel.
 +
* Check servo throw and dual rate setting for the rudder channel in the transmitter and increase the throw.
 +
* Receiver type "Standard": Check that the connector for the rudder channel (orange wire) is inserted correctly in the receiver.
 +
* Is the correct stick moved? Check stick mode of transmitter and have a look at the servo monitor. Is there any movement on the channel that you have connected the orange wire for rudder function to (Receiver type "Standard")?
 +
* Serial-wire receiver: Was the rudder channel assigned for rudder function at [[Manuals:MB_Plus:Receiver_setup_menu_B|receiver setup menu]]?<br />

Do not trim the rudder servo by using the transmitter as this will apply a constant rotation command to the unit! When you can't get the servo horn exactly 90 degrees this has no significant effect. The "90 degrees rule" only should give some good basis for initial linkage adjustment. In flight the system will control the servo all the time anyway, so it is not an issue if the center position is slightly offset.

It is more important, that the tail servo linkage is in general adjusted correctly, so that you get asymmetric tail pitch throw: 40 degrees against main rotor torque direction, approx. 6 degrees at center position and 20 degrees in main rotor torque direction.

Anyhow the color is not a fixed value that is a must to reach. If you get blue you have something similar to 80% usable servo throw. The further you can go the higher the value will be. So everything from blue upwards will give a good resolution and you won't feel any disadvantages. If using good, precise high class servos, strong and with fast speed you even can fly with only red LED without any noticeable difference. Also rotorblades (flybarless blades or not) can make a difference.

On a 250 or 450 size heli you should try to get "dark blue" at exactly 6.0° as here servos normaly are not so precise.

Watch the running LED lights during the init phase: If the lights A - G light up the sensor's rest positions are beeing calibrated, H - N show determining the RC channels and their center positions. Initially the chase is from A - N. If one step is done the indication light for this step will quit running.

===The gyro sensors do not seem to work correctly.===
 +
''The rudder servo does not react or reacts very slowly to rotation of the helicopter. (The same happens to the elevator axis.)''<br />
 +
Maybe the gain of tail gyro is too low.
 +
* Check assignment of gain channel and adjust the gain in the transmitter as described [[Manuals:MB_Plus:Flying|here]].
 +
* Check for correct wiring or setup of tail gain cable/channel.
 +
Additionaly when the elevator doesn't seem to work either, maybe the wrong mounting orientation has been selected. So select the correct mounting orientation in Setup menu point '''A'''.<br />

===How can I increase rotation rate for aileron, elevator and rudder?===
 +
 +
The rotation speed of the helicopter is only determined by the length of the stick output signal. The gyros measure the actual rotation rate and the system will move the helicopter as fast as it is determined by the stick position. So simply increasing/decreasing the stick throw (mostly done by increasing/decreasing servo throw or using Dualrate in the TX for the specified function) will increase/decrease rotaion rate. Note that the rotation rate in first line has nothing to do with your cyclic pitch adjustments at Setup menu points J or L and also has nothing to do with the cyclic pitch when steering cyclic on the ground! In flight the system will automaticaly control the pitch as it is necessary to maintain the given rate. So always setup the cyclic pitch as mentioned in the manual and do not rely on what you see when moving the sticks on the ground.
 +
 +
The presets at Parameter menu point B are nothing else than different preset dualrate/expo curves inside Microbeast. Choose the preset that fits your preferences best and that gives you a good amount of rotation rate. Using the presets (except for the "Transmitter" preset) it is recommended to not change the output signal in the TX significantly as especially when using expo this will bend, compress or stretch the curves, leading to very strange flight behavior. It just is not like adding 5% of expo as the curves between TX and Microbeast will multiply and not sum together! Anyhow you may do small adjustments in stick throw, i.e. for slightly increasing the roll rate. This will not significantly deform the Microbeast's internal curves.
 +
But easiest thing to do would be to switch flight behaviour to preset blue (="Transmitter") and adjust the curves in your transmitter just as you like. Therefor we suggest to start with a setting of 70% D/R and 25% expo on cylic and 85% D/R and 40% expo on tail in the transmitter and adjust the curves accordingly. When setting parameter B to "blue = TX" the internal curves in Microbeast will be "disabled". Here 100% stick input will give a rotation rate of apprx. 600deg/s on the rudder axis and apprx. 400deg/s for the cyclic movements (this may vary depending on TX brand as any manufacturer use another signal output as maximum, so this also can be 107, 110% or  95%).
 +
We are often asked which percentages of expo or dual rate corresponds to the different presets. As manufacturers calculate expo curves different, we can't tell you what our preset curves correspond to which TXs expo values as we use our own expo calculation and there is no data available for comparing. We did outfly these values and programmed them in the source code so we can't tell what these are in Futaba or JR percentages. If you want to use a specific preset as your starting point we suggest to connect your MICROBEAST to the StudioX software. Here you can see the different values for each control behavior preset and you can create a custom preset for which you may use the given values and adjust them until they perfectly fit your flying style.

'''Note for MICROBEAST/AR7200BX/Ar7300BX:'''
 +
If Parameter menu point B is set to preset "blue" and the tail gain is switched to heading lock mode you can see in operation mode by the Status LED state at which tail
 +
stick position the maximum possible rotation rate on rudder will be reached: At that specific tail stick position the Status LED will start to flash. Moving the stick
 +
to this point in flight the rotation rate of the helicopter will be as high as the gyro can control. Increasing the stick throw further the LED will go off. At this
 +
point the rate control is switched off and the tail will spin freely. Here the only limit is the tail pitch throw and normaly the tail will spin ultra
 +
fast. This can be used for performing tail slides or turns with very fast spinning tail. For normal flying around you should not use this as you may
 +
accidentaly steer into the uncontrolled area and the tail may spin too fast or very uneven. So please check on the ground that the Status LED will not go off when giving
 +
full rudder stick deflection in your default flight modes.

===The tail rotor turns around instantly when doing backwards flying.===
 +
* Tail gyro gain too low. Increase tail gyro gain as described [[Manuals:MB_Plus:Flying|here]] and make sure you're using the tail gyro in HeadingLock mode (using Normal-Rate mode it is nearly impossible to perform backwards maneuvers!).
 +
* No sufficient thrust produced by the tail rotor. Check tail pitch angles. Reduce the maximum amount of available tail pitch throw at [[Manuals:MB_Plus:Setupmenu_E|Setup menu point '''E''']] to prevent the tail blades from stalling or increase the tail pitch angle if it‘s too small. Use different (larger) tail rotor blades or increase the rotor rpm.<br />
