Can anyone confirm that it's safe to install the upgrade kit and use the original Zenmuse H3 2D gimbal with it? I've heard that you can't upgrade the gimbal's firmware and that the V1 Gimbal's firmware MUST be upgraded so that the motors on the gimbal don't fry. I heard that the V2 gimbal will be ok.. I'm confused as to weather I should install the upgrade kit and my Zenmuse v1 gimbal.. Neither are yet installed.
