FPV help needed

[Riley Jordan]

I have a Cheerson CX-20 quadcopter and i recently bought the FatShark PredatorV2 RTF FPV Headset System w/Camera and 5.8G TX system from hobby king, and when i went to fly it this morning my quad kept loosing signal or something and crash 4 times and i have flown there many times before without crashing but ever since i got the FPV it keeps crashing, i was wondering what happened and how i can fix it? Could someone please help me?
Riley.

How are your antennas positioned? Make sure your rx antennas aren't near your fpv antennas. I'm assuming your uses 2.4ghz for you controller?
