Marcel,
Very nice plane - congratulations. We need more information to
help judge your performance. Like the weight of the plane. Also I don't
have the same engine but it does take time for it to wind up to full rpm
after getting trimmed to straight and level.
Safe flying and best wishes to you
Joe Horton, Coopersburg, Pa.
