I am trying to balance the H4-3D gimbal but I end up with my GoPro down to the left side... Is there something to do with the IMU? How do I fine tune the horizon? What am I suppose to do?

Dear roberto, are your convenient to leave your E-mail address, there will be gimbal techinical support to contact you.

Hi Roberto,
I have the same problem with you Roberto . I try to do IMU advanced calibration, through Phantom assistant software but nothing happened! I went to our local represent  in Athens, Greece and reset the gimbal Zenmuse H4-3D firmware, try again to do IMU advanced calibration, after installing again the firmware,  but nothing!! .....the same problem! It has a constant small angle (about 5 degrees) relative to the horizon!!
Now I am writing a letter to Blair.Tang (DJI  service Guy) about all the story of my Zenmuse H4-3D gimbal.
Did you solve your problem and if yes how?
Thanks,
