Why not install the pitot on the top of the rudder, the Jodel has a
full flying rudder so it would always be pointing into the relative
wind.

Pitot tubes remain reasonably accurate within the alphas and betas
encountered in normal flight. It is the static port that typically
suffers accuracy in beta (with attendant ASI errors). Best to mount
your pitot tube on the fixed airframe, not your full-flying rudder.

Also why not terminate the static line inside the wing, seems to me
the air inside the wing would be relatively static.

Bad idea. The pressure inside your wing could vary widely with both
airspeed and lift depending on where the various air gaps in your wing
are. Use a well-placed static port or combo pitot-static head.
