Thanks all for your comments over the last couple of weeks.  I _think_ I have 
now fixed the problem.  In the end, it was probably Christophe De Wagter that 
put the final piece into place for me.

It all stems from when I originally set up the airframe and radio file.  I used 
the R\C and simply tweaked the orientation of the Radio file until everything 

In fact, I think that the servos needed reversing and not the radio file.  So I 
had tuned the plane to fly upside down ;-)

When it came to the vertical IR, I had the orientation correct, so the major 
orientation in the PFD looked correct.  Using Chistophs advice regarding 
blocking the sensors with warm objects, I was able to work out what was wrong.

On the bench I now have an airframe that responds correctly to R/C commands in 
MAN and to moving my hot hands around the IR sensors when in AUTO1.

As per numerous suggestions, I've disabled the roll gyro until further down the 

Next steps are now to start the tuning process again now that the orientations 
are all correct!

Thanks again to Christophe, Cedric, Volker and all the other commenters for the 
suggestions.   Fingers crossed for an AUTO1 flight soon!
