Calibration
The ARF-MikroKopter uses different sensors which makes a flight quite easy.
The ACC-Sensor as well as the Compass are already calibrated at the factory.
On the other side the Gyros must be calibrated new after each switching ON (or battery change).
If you don't do that you are not able to start the ARF-MikroKopter and a warning signal will sound while trying to start.
During calibration of the sensors the Kopter need to stand absolutely still.
Moving or shaking the Kopter can lead to error messages.
During calibration of the ARF-MikroKopter the trim for the control sticks of the transmitter should be in
middle position. Otherwise it will lead to malfunction.
A new calibration of the ACCs or the compass may be necessary after a software update.
If the Kopter in the "GPS Hold Position" (see: Features / flight modes) makes circles around the logged
position the compass should be re-calibrated.
Acceleration Sensor (ACC)
The acceleration sensor (ACC) helps with the automatic and straight hovering of the Kopter. If the Kopter, while hovering
(calm wind), begins drifting sideways the ACC should be re-calibrated.
To calibrate the ACC the ARF-MikroKopter must stand absolutely straight. The easiest way is to remove the cover and
place a circular level on an even spot of the MK-GPS.
Now the Kopter needs to be aligned until it is horizontal.
Once that is done you can start the calibration.
On your transmitter you do as follows:
• Throttle-Stick up
and
• Yaw-Stick to the right
A confirmation tone comes from the Kopter.
(Example transmitter: MODE 2)
