Aj,

Thanks for the info about using nasal bindings.  I looked at the docs for 
joystick configuration that were installed on my system as part of installing 
FlightGear and there was no info about using nasal there.  Perhaps the docs 
could be updated.  I found that this works MUCH better. 

Here is an updated version.
