==How can I increase rotation rate for roll, pitch and rudder?==

==How can I increase rotation rate for roll, pitch and rudder?== <!--T:2-->

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 servos until the helicopter reaches the rate that is commanded 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 rotation rate.<br />

The presets at Parameter menu point '''B''' are nothing else than different preset DualRate/expo curves inside MICROBEAST / MICROBEAST PLUS making the heli rotate slower or faster at a given stick input and making the stick contol more or less sensitive around stick center position. 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 internal curves, leading to very strange flight behavior (anyhow, doing small adjustments in stick throw, i.e. for slightly increasing the roll rate should work without any issues).<br />

* If the heli does not flip / roll / rotate fast enough even if you've fully increased the stick throw in the transmitter check the maximum amount of cylic pitch at Setup menu point L and the maximum rudder servo deflection at Setup menu point '''E'''. When the cyclic pitch or tail pitch is not sufficient of course the system can't rotate the heli faster than the pitch allows.}}<br />

* The helicopter's linkage ratio is not suitable for flybarless usage. In Setup menu point J adjust the cyclic pitch to exactly 6 degrees and make sure the color of the Status-LED lights up “blue”. If this is not the case change the mechanical linkage ratio of the helicopter (i.e. by moving the linkage balls further inwards on the servo horns, by mounting longer linkage balls on the swash plate outer ring or by mounting shorter linkage balls on the swash plate inner ring).

* 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 />

* Please check whether everything works properly on the ground. When giving collective pitch input the swash should move up and down properly. When giving cyclic input it should return to zero after a few seconds. This is also especially after turning on Idle up or switching between flight conditions in the transmitter. Make sure that there are no trims, mixers, etc. in any flight condition and also make sure that the sensor directions for aileron and elevator are setup correctly ([[Manuals:MB_Plus:Setupmenu_M|Setup menu point '''M''']])!

* When taking off do not use too much cyclic input. Just let the motor come up to speed and then quickly give pitch input. Only when the helicopter is airborne the system can operate and control commands. If the helicopter sits on the ground, however, a stick input(= command to rotate the heli) would have no effect and the system would increase the cyclic pitch more and more desperately to perform a rotational movement. As soon as the helicopter will get "light" by increasing the collective pitch it will tip over abruptly. So always make sure that the swash is aligned straight during starting procedure!

* One could also consider a voltage fluctuation of the receiver power supply. It is necessary that this is stable enough, especially in terms of duration and whether the cable cross-sections and the connecting system are of sufficient size. The power supply should be dimensioned at least twice or three times as strong as expected since very high current peaks can occur in milliseconds which make the voltage sag dangerously low. In this context it may happen that the helicopter flies normally for a few minutes and then suddenly turns or rolls away in flight or even after landing the swash plate turns by itself to one direction. This is a sign that the MICROBEAST made a quick reboot in flight but because of the severity or duration of power failure it could not completely reload all calibration and sensor data. In this case the cause must be found and rectified and it mustn't/shouldn't be flown anymore since the receiving system was apparently close to a total failure.<br />

{{QUOTE|'''Please do not confuse:''' A slight tilt of the swash plate when the heli is standing on the ground is absolutely normal when the so-called integrators are not fully discharged. Especially when carrying the heli or steering the sticks this can happen as the system tries to perform the necessary commands. But as the helicopter will not move as intended the system tries to keep the servo movement until the helicopter may turn. Only after approx. 30 seconds without moving the helicopter or touching the sticks, the swash will return to its normal position as the systems slowly clears its memory. The exact amount of time for this depends on the position of the thrust stick. In the middle position is the discharge at the fastest. So if possible always keep the thrust stick in center position when the heli is on the ground so that the swash plate stays leveled. Once the helicopter is airborne you will not see any of these effects as now the control loop can operate as intended. As described [[Manuals:MB_Plus:Flying|here]] to center the swashplate you can also move the cyclic stick(s) to full deflection once as this will clear integrator instantly. Only if the swash moves downright by itself to full-stop even after correcting with the sticks and only cycling power off and on resolves this problem, check that your transmitter does not send any unwanted control commands (trimming active, stick pots worn out, ...). If this is not the case please contact support as maybe there is some problem with the sensors then.}}

The flashing Status-LED shows that a software-reset occurred during operation. This can have different reasons:

* The receiver power supply does not seem to be sufficient. The voltage during operation dropped in a critical area (<3.5 Volts). Use a stable power supply and make sure that the wiring and plugs are dimensioned big enough and feature low contact resistance. On large helicopters we recommend to use the MICROBEAST PLUS HD or AR7300BX unit with high power input.
