-YASim aerodynamic model for a P-51D mustang
-Started 2003-04-24 by Jim Wilson

-This aerodynamic model is based on three-views, unauthoritative
-performance data, and wild guesses.  These sites provided particularly
-useful information or were simply fun to visit:

-Performance data:

-http://www.olympicflightmuseum.com/aircraft_gallery/p51d_mustang.htm
-http://www.btinternet.com/~lee_mail/P51.html

-Weight and balance:

-http://www.nzfpm.co.nz/aircraft/p51d.htm

-Three-view:

-(Note: I have local copies if this url becomes un-available)
-
-The reference datum for measurements is the nose.
