Fly it how you do to make it glitch, then try again with the FPV transmitter powered off to see if it goes away. When you have proved that is the issue, move the components to get the FPV transmitter and antenna far away from everything else. Try a separate power supply for the FPV and no connections back to the RC.
Thanks and my apologies - I did leave out that when it started glitching I turned off the FPV gear, and even subsequently even removed it but still had the glitching.
When the FPV gear was on, it was powered by a separate battery. Sorry for leaving that info out in my initial post
