I know that if I was building a Kitfox then I'd mount the static ports either side of the fuselage in the position mentioned above. They look pretty simple to mount and I'd definitely fit two and have the T running to the instruments.
Unfortunately for me, who seems to want to do things differently to everyone else the Eurofox does not have a recommended position for static ports, since they do just use cockpit pressure. I would imagine the Kitfox recommended position would be very similar but I don't really think I'm up to making holes in places that I don't know for sure are going to work.
I appreciate the thinking behind the wing pressures and will do some more research
