The original Dykins Europa profile shows a small amount (about 1/4") of
reflex in the trailing edge.The template called up by the profile
co-ordinates in the manual is too crude to reflect this subtlety (or I was
too stupid to spot it when I built mine). What effect it has I can't say,
other than that gliders get better high speed efficiency with reflexed
flaps.
So, in answer to your questions, "more speed"? and "up is better/originally
intended".

PS which GEO are you using?

> I am getting my plane ready for what I hope is my final FAA inspection
before being able to fly. I have my flaps positioned so that the bottom of
the flaps are flat with the bottom of the wing. I noticed at Oshkosh that
others have the flaps positioned so that that they align with the top
surface of the wing & level with the ailerons. What affect will this have
on performance? Which is better?
