have had a few close ones !
So have I Dick. And most right around a busy airport where see and avoid should be in full use.
If you've ever flown with another Kitfox you know how small we look in flight compared to say a Cessna 172 . Hence my Kitfox is painted "don't kill me" yellow. No you won't find that color in the Poly Fiber color chart. The only other way to be seen other than TCAS in every aircraft is with lights. If the other guy actually looks out of his cockpit he will see you with wigwags of extreme brightness.
The microsun would be in my wingtips if it would physically fit. It will be on my cowling for sure.
