Interesting that you got it to work.  I have never been able to get it to work and have previously installed the fix.  I tried again today and it sort of works.  Very bad porposing of the aircraft once you change the pitch.  I have been able to fix that by completely turning off the A/P and Elevator and then turning them back on again.  Seems to fix it.  Not ideal but something I can work with and the aircraft is at least flyable.
