Graham,
the flaps are only sealed in the up position, by the leading edge of the
flaps pressing against the seal attached to the inside of
the channel. Sealing the flaps in the down position would defeat the
benefit of slotted flaps with their own lift producing
air-foil,in my opinion. The old L 13 Blanik sailplanes used to have such
flap-seals, which would then deteriorate over time.
However, there are now all kinds of such seals available, including those
stocked by camper-trailer and marine suppliers
and installation is particularly easy on the Europa. Try it, you'll like it!

that makes sense, the only caveat is that there needs to be a small
amount of reflex on the trailing edge, (TE up) and the seal could
compromise that

Graham,
How much reflex for best cruise performance? I am thinking of working on
my flap rigging to help the heavy left wing and instead of lowering the
left one slightly which sounds easy thanks to Bud Yearly's suggestion, I
would like to achieve the slight reflex you suggest.And then also the seals.
And thanks very much for the mono landing advice. Bob had a limited
amount of time to work with me, and after a 7 year build process I need
a lot of work! Unfortunately that will have to wait till fall as I
leave Saturday for Alaska for 6 months of work. Next year I will fly
N211KA to AK!

Can you o[pen the attached dxf file? It is an Autocad drawing exchange file.
The leading edge is very important too. It should be quite sharp radius
