Download this flight simulator VI library from community member Torbjorn Tjellden. His code is based on his 3D-script viewer, which has three inputs: the script with leaves and variable names, the definition of leaves, and the variable array.  For the airplane, those variables control the wing, flaps, roll, etc.  Torbjorn is currently working on an editor for the landscape and additional features.  Visit this wiki collaborate on his code, comment on the functionality, or just have some fun.
