lake_flyer said:Black on the underside (for high flying against cloud or sky backdrop) and a signal color like yellow (for low flying against a green/grey backdrop) on the topside works really well for visibility. A bright white headlight certainly helps to determine front from back. But in bright sunlight it is still practically impossible to see where you're quad is heading when over 300m out (I don't wear glasses for distance). In the dark I can see the lights for about 450 m before they hide between the stars.
OK respray done. I will leave the props for now. No prospect of a test flight for a while because of the winds.
