Step 12 - Calibration

Requirement

Step11 has been read.

Calibration

Now that in the previous "Step's" the right function of the transmitter has been checked and (if necessary) the right mixer has been set,
you can start with the calibration.

Calibration ACC

First at all you calibrate the ACC. That you have to do only one time.
(Only in case of an error or after downloading new software you should repeat it)

1. The Kopter should stand straight.

(An inclined position influence the calibration and leads to errors during the start or in the flight behavior.)

A circular level can help to align the Kopter in a straight way: Link

2. Over the transmitter the ACC will be now calibrated.

Here now you need to move the sticks as follows:	On a transmitter in MODE 2 it looks like in that way:
Throttle up + Yaw right (hold it for more then 5 seconds) Nick middle Roll middle

3. The Kopter acknowledges the ACC calibration with beep-tones.

Depending on where in the 5 Setting's you are the Kopter confirms with that numbers of beeps.
Example: We are in the Setting 3 (Easy). The Kopter "beeps" 3x to confirm.

DONE

Calibration Gyro's

Before every initial startup or after changing the Lipo a new calibration of the Gyro's must be done.
If you don't do it the Kopter will give you an error message and "beebs" while trying to start the engines.
INFO: The servo outputs of the FlightCtrl are only available over the transmitter (if set) after the calibration of the gyros. Not before.

1. The Kopter should stand on the ground and not moving or shaking (IMPORTAND !!!).

(The Kopter can stand horizontal or also be stand hillsided in an inclined position. For a horizontal flight of the Kopter the right calibrated ACC will help!)

2. Over the transmitter now calibrate the Gyro's.

Here now you need to move the sticks as follows:	On a transmitter in MODE 2 it looks like in that way:
Throttle up + Yaw left Nick middle Roll middle

3. The Kopter acknowledges the ACC calibration with beep-tones.

Depending on where in the 5 Setting's you are the Kopter confirms with that numbers of beeps.
Example: We are in the Setting 3 (Easy). The Kopter "beeps" 3x to confirm.

DONE

Calibration Compass

Is on a Kopter already the GPS-System installed (NaviCtrl, Compass, MKGPS) you must calibrate the compass.
Until this is done, in the virtual display you see the "error6" message.
(If you doesn't calibrate the compass, you can not start the Kopter and he will "beep" if you try to start him.)

It depends on a right calibrated compass that the function of the GPS-functions like PositionHold" works well.

1. Disconnect the Kopter from the MK-USB.

If you want to calibrate the compass correctly you should go outside.
Subjected to any disturbing magnetic influences you shouldn't do the calibration close to the house or close to power poles.

2. Over the transmitter the compass will be now calibrated.

The LEDs look in that way:

NaviCtrl V2.0 =>
- green and red LED ON.
NaviCtrl V1.1 with MK3Mag=>
- NaviCtrl V1.1 = green and red LED ON, MK3Mag = green LED flashes.
The calibration will be done in several steps:

Step	Function	Example View / Function
Step 1 Initiate compass calibration	Nick down then Throttle up + Yaw left (The Kopter beeps 1x)	On a transmitter in MODE 2 it lokks like in that way:
Step 2 Start Calibration	Pull Nick down 1x (The Kopter beeps 2x and the clicking starts begins)
Calibration of the X-Axis (Nick-Axis)	The Kopter with the front (Arrow direction of the FlightCtrl) pointing to the South or North. Then rotate the Kopter a couple times over the Nick-Axis until the buzzer stops with the clicking starts.
Calibration of the Y-Axis (Roll-Axis)	Rotate the Kopter by 90° The clicking starts again. Rotate the Kopter a couple times over the Roll-Axis until the buzzer stops with the clicking starts.
Step 3 Finish the calibration of the X and Y-Axis	Pull Nick 1x down (The Kopter beeps 3x)
Step 4 Start calibration of the Z-Axis	Pull Nick 1x down (The Kopter beeps 4x and the clicking starts begin again)
Calibration of the Z-Axis (Yaw-Axis)	INFO: Here it doesn't matter if the Kopter shows with the X or Y-Axis towards South (North). Rotate the Kopter a few times over the Roll- or Nick-Axis until the buzzer stops with the clicking starts.
Step 5 Finish the calibration of the Z-Axis.	Pull Nick 1x down The Kopter confirms it with 2 beeps

3. Now that the Kopter "beeped" 2x after a successful calibration that part is done.

If everything is OK the red LED stops lighting after a few seconds on the NaviCtrl V2.0 with integrated compass.
If you use a NaviCtrl V1.1 with MK3Mag the red LED on the MK3Mag lights permanently.

DONE!

After the calibration of the compass the Kopter can be connected again to the MK-USB.

Check in between

After those settings:

Set the right mixer (if necessary)
Calibration ACC
Calibration Gyros
Calibration Compass (if GPS-System has been assembled)

... all buttons should be green in the KopterTool:

Only FlightCtrl at the Kopter	FlightCtrl with GPS-System at the Kopter

Everything OK? Then it continues here:
