= Step 13 - Motor, Propeller and Gyro Check =
== Requirement ==
 * '''Step12''' has been read.


== Last Check ==
Now the function of the !FlightCtrl and of the engines should be checked.<<BR>>
If not already done you can remove the propellers now for the motor-test. <<BR>>
In that way you can check safely the direction of the rotation and also the function of the engines and without that the Kopter lifts off.<<BR>><<BR>>

== Motortest ==
Here now you need to open under the virtual display the tab '''"Motortest"'''. <<BR>><<BR>>

The procedure is as follows: <<BR>><<BR>>

{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=77448&g2_serialNumber=2}}<<BR>><<BR>>

 * '''"Motortest active"''' has to be activated.
 * '''"Address"''' = Choose motor you want to test.
 * '''Slider''' push slowly with the mouse upwards.

That can be done now for each motor. <<BR>><<BR>>

'''Tipp:''' <<BR>>
If a motor is turning the wrong way it is actually enough to switch two of the three motor cables on the appropriate BL-Ctrl.<<BR>><<BR>>

== Propeller assembly ==
On the Kopter left and right rotating propellers are used. Those ones have to be assembled correctly.<<BR>>

The propeller with its direction of rotation looks like in thast way: <<BR>><<BR>>

||<class="MK_THeader">Left-rotating propeller (TOP-side)||<class="MK_THeader">Right-rotating propeller (TOP-side)||
||[[http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=97975&g2_serialNumber=2|{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=99987&g2_serialNumber=2}}]]||[[http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=97980&g2_serialNumber=2|{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=99988&g2_serialNumber=2}}]]||

After that describtion you can assemble the propeller back.

{{{#!wiki tip
'''Info'''

Where does the term "left-rotating propeller" come from?<<BR>>
In an airplane you usually sit behind the propeller and you are watching the back of the propeller. This one turns around left if you view it from behind. That means anticlockwise.<<BR>>
This propeller is called "left rotating propeller" . This direction is used for all current propeller.<<BR>><<BR>>

We see the direction of rotation of the propellers on our Kopter from the __TOP__. We are looking on the TOP-side of the propeller.<<BR>><<BR>>
 * A '''left rotating''' propeller rotates clockwise, seen from above.
 * A '''right rotating''' propeller rotates anticlockwise, seen from above.

== Function of the Gyros ==
So that the Kopter can fly straight are Gyros assembled on the FlightCtrl Gyros for all three directions (X,Y,Z). <<BR>>
This function can be checked with the scope in the !KopterTool. <<BR>><<BR>>

You should: <<BR>>
 * Choose FlightCtrl 
 * Choose analog datas (click) => !AngleNick, !AngleRoll, !AccNick, !AccRoll, !GyroYaw
 * Click the '''START''' button (changes then into "PAUSE")
 * Move the Kopter in Nick, Roll and Yaw direction.
The scope should look like in that way: <<BR>><<BR>>
