hy not install the pitot on the top of the rudder, the Jodel has a

disadvantage of having the pitot in the prop wash?


Run a seperate tube from your proposed location to a spot where you can
Y the connection into your pitot system and have both lines exposed in
the cockpit. Take the bird up and clamp off each in turn. If the
airspeed changes dramatically, it may not be a good idea. Try the test
in different flight regimes.


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


It may be static but not at ambient pressure. The wing creates a slight
vacuum behind it that will throw off your altitude measurements.
