In my Classic I used a suggestion made by a Canadian EUROPA builder:
Installing three static ports, each equally separated 120 degrees from each
other located on a circumferential circle just past the rear (XS) baggage
bay).
One locates fuselage bottom centre (to let rain water flow out), the other
left and right, located about a foot higher than fuselage side centre line
where you usually would find the dual static ports.
I have no issues detected when flaring high, very little with slipping. Spe
ed changes neutral. Works like a charm. No special fittings each either. Ju
st reduxed an aluminum pipe ending for each port inside the fuselage and dr
illed through the fuselage three small 1/8 inch holes (drill only through o
ne side) of the pipe.

Paul,
A word of advise.
The Dynon Pitot with AOA (heated or not) is a good pitot, but the AOA is no
t effective (in my opinion) unless the tip is near the leading edge and dro
pped down using the now pretty standard Gretz mount.
As the air flows beneath the wing, the relative wind 4-6 inches off the low
er surface is nearly parallel to the wing lowr surface up to stall. Howeve
r, within a few inches (no more than about 8, it is not bad.
As for static ports, I was not impressed with the side ports in the Europa.
Especially with the flaps down on the old Classic. Slipping did induce e
rrors.
I prefer on all my IFR Europa's to use the XS pitot tube for the A/S and th
e static for all instruments. This is dirt simple, the parts are in the bo
x, and since the Dynon pitot is located on the other wing, easy to plumb.
Consider an Alternate Static Source. The Cockpit Static is quite good in m
y flight tests in the trigear and mono over the entire speed range, unless
you have some sort of pressure ram air system with a tight cockpit... Just
in case you are flying in extreme icing as a death defying feat.
I do not use a certified alternate static source valve. I install a simple
toggle valve which looks like a switch in the panel. Marvalve Co. 1815 C

It's fun to experiment if you are allowed.

Subject: Europa-List: static ports
Hi All, Just getting the pitot system installed & am wondering where the be
st place for the 2 static ports should be? Ive already installed the Dynon
AOA/PITOT probe in the wing thus leaving the static ports to be mounted. I'
d like them near the front to keep the tubing runs short if poss. Any ideas
please? Paul Munford. Kit 625 trigear. THANKYOU
