Detlef,

Many thanks, and again, i hope you did not loose to much time, you started =
to=20
work on your model.

On my side as i said before, that model was ready some years ago (i just=20
included some instruments taken from others recent existing aircraft, these=
s=20
instrument must be improved)
My target was to make a variant, in order to answer an old wish  =3D>to mak=
e the=20
St Exupery Aircraft which was the last he had flown, he never came back fro=
m=20
mission:
 here a link
http://www.flyandrive.com/cadresaintex02.htm =20
and that other link  (sorry in French only)=20
http://aeroclubstdizier.free.fr/historique_st_ex.htm
today we know i was shot over Marseille.
here the link
http://www.aero-relic.org/English/F-5B_42-68223_St_Exupery/e-00-stexuperyf5=
b.htm

I will  make that P38 "F-5B" variant (with a pilot who could look like St E=
X=20
face :)  )


I mainly work with the documents, that i have are from paper ( old history=
=20
books aircraft, and specialized magazines, more than 50 years=20
collection  :)  ).

I could read that P38 was very difficult to fly, and the victories, when =20
fighting ,where due to the main quality high climb speed and altitude=20
capability. The low speed manoeuvrability being very difficult.

With Flightgear we can  enjoy  to gather the history acknowledge and these=
=20
specific aircrafts  which where involved in the History.

It would nice to read your manual, so i could learn more on that "wild=20
beast" .

On a private mail i will send you my private address mail.

Cheers
