Dave.
I don't profess to be a specialist but I'm on the understanding that the
Europa has a very benign stall anyway. It won't give you warning unless you
fit stall strips. The PFA make it mandatory here unless there is another
warning device. When you have them set right there is a most pronounced
buffet, you would be fast asleep to not notice it. You seem to say "it was a
non-event" and that is what a benign stall is. IMHO you need to investigate
the stall strips and locating them, the position is very critical and a
there is a template in the Owners Manual for the initial location from that
1mm up or down begins to show the buffet in very pronounced effect. Mine are
just taped in place in the absence of invading the wing with a permanent
fixing, and have they have been life savers, like buffet three times leaving
ground effect too early .
Hope this helps?

They added ballast o the tail to get the CG aft. I don't know where it is
right now, but I added the same amount of weight to get it back to 60.6.
When
I was trimmed for approach, I had about 25% trim forward of the aft limit
when I flew it. I typically was flying 65 mph on approach initially and that
was what I trimmed for. The trim was neutral for the takeoff setting. The
stall was a non event -- the airplane barely would buffet and it just saw an
increased sink rate -- very mild stall. I will know more about mine in a few
days/weeks.
