The replecemnt operation does it need any calibration afterwards
Do you knowe if the are any places in northen europe or just in europe.I have never replaced a gimbal yaw arm. With the help of YouTube, you should be able to handle it. If you don't think you can though, then it would probably be best to send your Phantom away to be repaired.
Thanks very much just bit unsure because have been watching those videos looks pretty complexCan we assume u are in Finland? If so are there any repair shops near you or within shipping at a reasonable cost distance? If the answer is no, watch those YouTube videos over and over until you feel comfortable doing it. I see u are a young man. You should be trainable.. I am 72 and started repairing these about a year ago. I can now rebuild one in 20 minutes. It may take you an hour or so but you can do it. Just make sure you have all the parts and the correct tools. Take photos as you take it apart. Be VERY careful of the locking clips that hold the ribbon cables in. Too much force and they break off. There is no fix when this happens. Watch how u put the camera on the pitch motor. If it is upside down it will do a hula dance for you. The flat on the shaft is on the same side as the ribbon cable connection or back of camera.
