Faq tipOver

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 (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!

Tilting in flight: Remove the main rotor blades and let the helicopter run in all speeds on the ground (beware of the rotating parts!). Again the swash should move straight up and down when giving pitch inputs. If at a certain speed it starts to tilt in one direction and this will depend on the rotor speed then that is almost certainly a vibration problem which confuses the sensors in the Microbeast. Trying different adhesive pads might help (smoother or firmer mount) or installing the unit in another location. But especially in the electric helicopter that brings in most cases nothing and there certainly is an error somewhere on the helicopter.

This can be: slightly bent hub of the tail rotor, jammed or defective ball bearings, tail blades / tail rotor is not properly balanced, engine bell not balanced / comes at a certain speed to vibrate or motor bearings damaged making the motor shaft vibrate, slipped ball bearings in the torque tube tail drive system or installed in the wrong position, main gear wobbles / unbalanced; motor shaft bends and runs rough, ... actually everything that rotates on the helicopter can be the cause of such a vibration. On electric helicopter you normaly should not hear, feel or see any mayor vibration (no vibrating tail fin or skids). Then it should normally be possible to attach the Microbeast only with a very thin adhesive pad on electric helis.

On nitro helis the situation can be slightly different as the motors do shake the more or less. This can lead to shaking of the Microbeast unit itself and will make the rotor pane wobble. So here trying different pads or a sandwich made of two pads and a metal plate may help to stabilize the unit better. Also the wiring can be the cause of such a shaking. But when the swash tilts as explained above the cause normaly is some very high frequent (abnormal) vibration and trying around with different kinds of gyro pads only disguises the real cause and may not help 100%.

Is the movement, however, abruptly or suddenly (similar to the twitch in a radio interference) this can especially be caused by static charges from the rear belt. Here a uniform electric potential across the entire helicopter should be done. The use of graphite spray, using a different rear belt or simply changing the belt tension can help.

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.

(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. This only will happen after approx. 30 seconds without moving the helicopter or touching the sticks, then the swash returns to its normal position. This also depends on the position of the throttle stick - in the middle position is the discharge at the fastest. A bug in the above named manner is present when the swash moves downright by itself to full-stop also after correcting with the sticks and only cycling power off and on can resolve this problem.)
