More information in the RCGroups thread. A well known poster seems to push the fact that the only difference is the camera gimbal unit, but the processing power in the gimbal somehow effects the live view video quality and transmission rate. This would indicate that the lightbridge hardware is the same, but cannot be fully utilized in the Advanced due to the gimbal. I don't know but allot of support calls are going to come in when people install HDMI boards in their Advanced model and see the poor quality. Just saying.
