I have a H3-3D gimbal and when it turns in a yaw rotation the roll axis tilts down to the right at the same time, and then when the gimbal yaws back to its initial position the roll turns back up slowly and levels out to its normal perfectly horizontal position. Very strange behavior, haven't seen this behavior earlier in any other gimbal. Im pretty sure the gimbal has experienced a crash or some other damage. So my question is, what can be the actual problem? The roll motor, or yaw motor, or something else? I need to find out which piece to replace on the gimbal? Thanks in advance.
