Please bare with me as i am totally new to this. Ive recently picked up a DJI phantom 1.1.1 with a tarrot gimbal and kumbacam basic fpv system all ready installed on it. The gimbal is already hooked up for the tilt function but the gimbal and video transmitter are powered by two separate lipos. Everything was working great up until today. I powered on everything to show a buddy of mine how it worked and everything was fine... 10 min later we go to fly and im getting a NO SIGNAL message on the monitor. I checked to make sure the batteries were good. gopro was on and everything seemed to be working the way it should but with no signal. At this point i dont really know what else i can do so any insight would be appreciated. Thanks Mark
