SETUPMENÜ K - Pitcheinstellung

Bei Einstellpunkt K wird der maximale positive und negative Pitchanstellwinkel festgelegt. Stelle dabei sicher, dass das MICROBEAST PLUS die Steuerrichtungen korrekt anzeigt. Das ist vor allem für eine korrekte Funktion der AttitudeControl (Rettungsfunktion) wichtig, hat aber auch auf den Normalflug Auswirkungen!

Wenn Du die Pitcheinstellung durchführst, muss die Pitchkurve im Sender auf Werkseinstellung stehen (z.B. -100 0 +100). Der Steuerknüppel muss den Pitchkanal über den ganzen Bereich bewegen!

Wenn Du die Einstellung beendet hast, kannst Du die Pitchkurven falls gewünscht ändern, z.B. für verschiedene Flugzustände. Für optimale Performance ist es aber wichtig, dass der grundsätzliche Arbeitsbereich bestimmt wird. Damit verbunden ist auch zu beachten, dass der maximale Pitchwinkel nicht unbedingt von den Vorlieben des Piloten abhängt, sondern vor allem auch durch die mechanische Auslegung und Leistungsfähigkeit des Helis gegeben ist. Bei einem Trainermodell zum Beispiel ist der Pitchbereich üblicherweise symmetrisch und reicht von -12 bis + 12 Grad. Ein Anfänger oder Scalepilot wird diesen Bereich möglicherweise gar nicht nutzen, vor allem nicht in die negative Richtung. Dennoch sollte der maximale Bereich in diesem Fall nicht auf zum Beispiel -4 bis + 12 Grad gestellt werden, weil das nicht den Möglichkeiten des Modells entspricht. Besser ist es, im AR7210BX Empfänger -12 und +12 Grad einzustellen und dann nachträglich über die Pitchkurve im Sender das Pitch entsprechend zu reduzieren. Im Handbuch des Helikopters findest Du Angaben zum optimalen Pitchbereich und der Pitcheinstellung.

Adjustment on the device

1. Move the thrust stick up and down and check whether the pitch is changing direction correctly. If not already done at SETUP MENU point I, use the reverse function for the pitch channel in the transmitter to reverse direction of pitch movement in case it is wrong.

2. Afterwards check the Status LED color: on positive pitch it must be blue, on negative pitch it must light in red color. In case the display is inverted (red = positive and blue = negative), tap the aileron stick once to reverse the internal pitch direction of the AR7210BX receiver.

3. When you move thrust 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 thrust channel in the transmitter for each direction just as far so that the Status LED changes from flashing to solid when the stick reaches the end positions. (Note: Do not increase the endpoints 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 reaching the end position.)

4. Finally adjust the maximum collective pitch when the thrust stick is at full deflection. Increase or decrease the maximum amount of collective pitch with the rudder stick (left = decrease, right = increase). Then move the thrust to full negative and again adjust the pitch using the rudder.

Always set the servo direction in the transmitter first, then check the display on the AR7210BX and change the internal control direction if it does not match the real direction. Do not change the internal direction in order to change the servo direction! This is only used for telling the system in which direction is up and down. Be very conscientious when doing this setup step as wrong direction will cause loss of control during rescue bailout and poor performance in general!

Setup with StudioXm

1. When you see the adjustment screen for the collective pitch move the thrust stick up and down and check whether the pitch is changing direction correctly. If not already done at SETUP MENU point I, use the reverse function for the pitch channel in the transmitter to reverse direction of pitch movement in case it is wrong.

2. Afterwards check the Status LED color and display in the app: on positive pitch the Status LED must be blue, on negative pitch it must light in red color. In case the display is inverted (red = positive and blue = negative), reverse the internal pitch direction of the AR7210BX by changing the direction in the app.

3. If the stick is not moving far enough, you will see the message "Increase!". In this case increase the servo throw/endpoint of the thrust channel in the transmitter for each direction just as far so that the Status LED changes from flashing to solid and the label changes to "OK" in the software when the stick reaches the end positions. (Note: Do not increase the endpoints 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 reaching the end position.)

4. Finally adjust the maximum collective pitch when the thrust stick is at full deflection for each direction using the + and - buttons in the app.

Always set the servo direction in the transmitter first, then check the display on the AR7210BX and change the internal control direction if it does not match the real direction. Do not change the internal direction in order to change the servo direction! This is only used for telling the system in which direction is up and down. Be very conscientious when doing this setup step as wrong direction will cause loss of control during rescue bailout and poor performance in general!

Extra info: What pitch is useful for my helicopter?

In general you can say "the smaller the helicopter, the more pitch you have to set". But it also depends on how much motor power you helicopter has, the type of rotorblades you use and finally in what you expect to do with the helicopter. So beginner or scale pilots will not need as much pitch as a 3D aerobatics pilot or high speed flyer. Anyhow, as already mentioned above set the pitch range in the AR7210BX receiver so that it roughly fits to your helicopter mechanics and its capabilities.

Heli size (electric)	Maximum pitch
250	13.0 - 13.5 degrees
450	13.0 - 13.5 degrees
500	13.0 degrees
550	12.5 degrees
600	12.0 - 12.5 degrees
700	11.5 - 12.0 degrees
800	11.5 degrees

Heli size (nitro)	Maximum pitch
.37 - .40	12.0 degrees
.50 - .55	11.5 - 12.0 degrees
.90 - .105	11.5 - 12.0 degrees
Gasser	10.5 - 11.0 degrees
