For anyone looking to build a small personal/business jet, Flight1 has released update 1.3 that includes keyboard command compatibility.

Most, but not all (just yet) of the Mustang's functions can now be controlled by assigning key commands. Some G1000 functions are assigned through the default FSX G1000 key assignment section. Other unique Mustang features are assigned using an Input.ini file.

This is a hugh update for the Mustang!
