Gentlemen thanks for your contributions

I do have more than the full movement required without the wings rigged
leading me to identify the control system as the prime suspect.

I shall re-start the process from scratch next weekend (very annoying how
work interferes with building)

   - I do actually have a smart tool but it's a long one which is too
   unwieldy for the ailerons so I will acquire a short one
   - Reducing the up throw by one degree per bud's instructions
   - Adjust the wing QD to 90 deg
   - level everything and check that the fuselage end is all correct
      - control columns vertical and parallel
      - centre the ailerons and ensure that the QDs are vertical (using my
      newly acquired short smart tool)
   - And then if that doesn't solve it start playing around with the
   fuselage link rods - where  I now suspect the culprit lies.
   - I think on reflection that I haven't followed the process carefully
   enough so ....I am going to do it again...

thanks Will
