Hi
I have just upgraded to 4hawks and working well. After 5 flights I have very bad pic on my controller or my ipad . I have checked the cables and all fine .
Any advice would be great
That looks like Zebra strips to indicate over exposure. You can turn Zebra strips off but I find them handy for setting exposure (shutter speed, ISO, aperture or EV).
BTW, I have found on the EVO II that the histogram is much more useful than the zebras or the EV meter. If you are familiar with reading a histogram you will learn that the histogram pretty much overlays the scene's exposure with the dynamic range of the sensor which is far more useful than zebras (because it will show you both under and over exposure in a single tool).
