Flying

After turning on the receiver power supply wait until MICROBEAST PLUS has fully initialized. This is displayed by a short movement of the swashplate servos. For initialization it is irrelevant whether the helicopter is leveled horizontally! Only important is that it is not moved as long as the calibration of the sensor positions takes place (LEDs lights A - G running). Also the control sticks of the transmitter must not be moved as long as MICROBEAST PLUS calibrates the stick center positions (LEDs H - N). If the initialization is not completed even after several minutes, read the Trouble shooting guide.

Like mentioned above the three dials should be turned to factory setting (centered horizontally), when using in small helicopters for safety reason dials 1 and 2 should be set to slightly below the center position. The tail gain channel should be set so that point G lights up, similar to approx. 50% tail gain adjustment. In micro or mini helicopters experience has shown that the gain must be lower (set to point D or 30%). Select the control behavior at Parameter menu point B to fit your flying style. If you‘re a beginner or unexperienced with flying flybarless helicopters you should highly decrease the maximum rotation rate, so change Parameter menu point B to “normal“ setting.

Warning.png Before the first take off, make a stick direction check and again make sure that the sensors are correcting to the right direction when you tilt, roll or yaw the helicopter by hand.

It is normal that the swashplate might move back to its original position only slowly after a stick input and that the servos don’t run at the same speed as your sticks. In comparison to a flybared heli you are not directly controlling the servos anymore but controlling rotational rates like for fly-by-wire. The control of the servo is left to the control loop of MICROBEAST PLUS. The system will try to move the heli to the commanded directions and as the heli will not move while standing on the ground, the system may give maximum servo input, even if you do not move the sticks or the heli anymore, as the system will "remember" the command for some amount of time. Thus it is also normal when the tail gyro is operated in HeadingLock mode, that the rudder servo will stay in its end position after a rudder stick input or tail movement and that it does not always react immediately to a stick input. And for the same reason, it is also normal that the rudder servo runs to the endpoints even with small stick inputs.

Just before lift-off make sure that the swashplate is horizontal and that the tail pitch slider is near center. You can shortly switch the tail gyro to Normal-Rate mode, in this mode the rudder servo will center itself if the rudder stick is released. To center the swashplate move the cyclic stick to full deflection once.


Avoid excessive steering during lift-off, otherwise the helicopter may tip over as it can't move as long as it's still standing on the ground (as decribed above the system tries to move the helicopter by applying more and more servo movement)! The best way is to give a fair and direct collective pitch input to lift the helicopter quickly up into the air. This demands some re-education if you have only flown flybared helicopters before.

Once airborne at first you should adjust and try to find the maximum possible amount of tail gyro and cyclic gain (dial 1). Then you may optimize the tail gyro by adjusting Parameter menu point D in case you're operating the tail gyro in HeadingLock mode and adjust the response of the tail gyro using dial 3. Additionally you may need to adjust the Cyclic feed forward (dial 2) and Parameter menu point C. If the helicopter does react very aggressive to stick inputs, change the Control behavior at Parameter menu point B to a lower adjustment and/or reduce stick throws (servo throws) in the transmitter for the specific functions. Likewise increase the stick throws and/or Parameter menu point B, if the reaction is too slow and gentle for you. When the control loop is well adjusted, you can additionally use Parameter menu points G and H to fit your flying style and stick feeling. To support the tail gyro you can activate the Torque precompensation at Parameter menu point F if necessary.
