The head (where the sensor is and lens attaches, not sure what else to call it), drifts to the left. I have to compensate for it with the joystick and after some time it will overcome that and jerk. I thought the new update would help, but it hasn't. Could it be dirt in the joystick?

Hello, there. Sorry for the late response. Would you please record a video for us so that we can let our engineers to verify your issue?

Try on gimbal settings to add pan recenter compensation, I've got same on the right. Also try to remove deadband on setting. Keep us in touch
