Rc Heli Gold When Using A Video Cam Attached To My Electric Rc Heli, There's A Ripple Effect On The Video.?

When using a video cam attached to my electric rc heli, there's a ripple effect on the video.? - rc heli gold

I think it is the magnetic field generated by the engine or buy electrical interference.
Can I protect the unit in any way without adding too much weight?
FlyCamOne V2 is the camera.
