= Step 9 - Check channels =
== Requirement ==
 * '''Step 8''' has been read.

== Check channels ==
Under the tab '''Channels''' will be displayed on the left side the individual channels and also their allocation: <<BR>><<BR>>

The channels '''1 - 4''' are assigned for the control of '''Throttle, Yaw, Nick and Roll'''. <<BR>>
The channels '''5 - 12''' are assigned to the '''POTI's 1 - 8'''. <<BR>>
Those POTI 1 - 8 can be assigned to each function in the setting. <<BR>><<BR>>

{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=91093&g2_serialNumber=2}}<<BR>><<BR>>

On the right side you can find a graphical display of the channels. Below the display there is the channel, above the set value.<<BR>>
Has been the receiver correctly set up and saved the display should look in that way: <<BR>><<BR>>

||<class="MK_THeader" width= 400px>'''Example View 1:'''<<BR>> Receiver with 12 channels ||
||<:>{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=99595&g2_serialNumber=1}}||
<<BR>><<BR>><<BR>>

Are the channels on the transmitter already correctly assigned the display may look like this: <<BR>><<BR>>

||<class="MK_THeader" width= 400px>'''Example View 2:'''<<BR>> Receiver GR-24 with 12 set up channels ||
||<:>{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=99603&g2_serialNumber=1}}||
<<BR>>

If you move the control stick or press a switch on the transmitter the appropriate channel (bar) should change.
<<BR>><<BR>>

We assume in the '''Example View 2''' that the transmitter is set up in '''MODE 2'''. For a transmitter which is set in a different mode the display is pretty similar.<<BR>><<BR>>

In the '''Example View 2''' we will see as follows:

 * '''Channel 1''' (Throttle) => Stick down
 * '''Channel 2''' (Roll) => Stick in middle position
 * '''Channel 3''' (Nick) => Stick in middle position
 * '''Channel 4''' (Yaw) => Stick in middle position
 * '''Channel 5''' (POTI1) => '''"ON"''' (i.e. Function !Hold Height => 2-way switch at the transmitter)
 * '''Channel 6''' (POTI2) => '''"OFF"''' (i.e. Function GPS "Free-PH-CH" => 3-way switch at the transmitter)
 * '''Channel 7''' (POTI3) => '''"OFF"'''(i.e. Poti at the transmitter on '''"left stop"''')
 * '''Channel 8''' (POTI4) => '''"OFF"''' (i.e. Function !CareFree => 2-way switchat the transmitter)
 * '''Channel 9''' (POTI5) => '''"OFF"'''(i.e. 3-way switch at the transmitter for further functions)
 * '''Channel 10''' (POTI6) => '''"OFF"'''(i.e. 2-way switch at the transmitter for further functions)
 * '''Channel 11''' (POTI7) => '''a little bit over middle position''' (i.e. Poti at the transmitter '''"turned not quite centered"''')
 * '''Channel 12''' (POTI8) => '''"OFF"''' (i.e. button at the transmitter to trigger a camera)

Are the values here as described in a range of '''"0"''' up to '''"254"''' everything is OK and it continues here:

##include_step_begin2



<<BR>><<BR>><<BR>><<BR>>
<!> Is the display looking like as shown here you __must set up correctly__ the '''"Servo settings"''' at the transmitter: <<BR>><<BR>>

{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=99597&g2_serialNumber=1}} <<BR>><<BR>>

Here we can see that the value of the Servo at the transmitter is __not__ in the range from '''"0"''' to '''"254"''' but only from '''"3"''' to '''"252"'''.<<BR>>
With these wrong servo values a malfunction can occur. To avoid that should be on the transmitter for __each__ channel the servo travel been adjusted properly.<<BR>><<BR>>

'''The exact procedure and the setting are described in the instructions of the transmitter.'''<<BR>><<BR>> 

'''TIPP:''' <<BR>>
At the transmitter the menu point is called mostly '''"Servo Settings"'''. <<BR>>
The servo travel can be changed for each channel at the transmitter. As a basic setting for each channel is 100%/100% set.<<BR>><<BR>>

Why 100%/100% ? <<BR>>
For each channel whether it's a joystick, switch, button or potentiometer on the transmitter, it rules the '''servo travel'''. This is from '''-125''' <=> '''0''' <=> '''+125'''.<<BR>>
The first 100% are assigned for the lower Servo travel (from -125 to 0) and the second 100% for the upper Servo travel (from 0 to +125).<<BR>>
To make it a little bit easier the servo travel is shown in the !KopterTool from '''0''' <=> '''127''' <=> '''254'''.<<BR>><<BR>>

Now you can select the values 100%/100% and increase it slowly. The number should change over the appropriate channel in the display of the KopterTool.<<BR>>
Both percentage values should be increased with the same value. Is now the lower Servo travel i.e. raised to 105% should the upper Servo travel also been raised to 105%.<<BR>><<BR>>

Everything OK? Than it continues here:
