Hi Kees,
These aren't my models, I don't have write access to the repositories, and my
copy of the bocian is about a year and a half old, but I'll offer a couple of
hints so you can fix it yourself locally, at least.

The Bocian slip indicator is controlled by a text file called
Aircraft/bocian/Models/yawstring.xml You can edit that file with a good text
editor. I recommend vim on linux or Textpad on windows. Find the line that
says:
<z>-1</z>
and remove the minus sign
<z>1</z>
That should change the sense of the yawstring.

The bocian is built on the YASim flight model which I am not very familiar
with... But I think if you edit the file called
Aircraft/bocian/bocian-yasim.xml and find the line that says
<spoiler start="0.24" end="0.38" lift="0" drag="5.5"/>
I think the start and stop are the location on the wing where the spoilers are
(0.0 is the wing root and 1.0 is the tip). Lift and drag are multipliers for
the change in lift and drag. You could try increasing the "5.5" value.
"11" might be a good first choice (in honor of Spinal Tap
