Hi Graham,
You are of course right.
I did check the incidence at the position (more or less) that you
describe (I read your tips in the "Hints and Tips") and it shows same
reading on both wings. But I measured the thickness at the same position
and they were different: about 8 mm or so. I.e. the wings are not 100%
symmetric.
My conclusion was: do it per manual as correct as possible and do the
"Graham check" before mixing the Araldite 420. If God is on my side it
will work ok. Otherwise I have to trim.
Regards,
Stephan

Hi Will,
It sounds risky. I know builders that have done it without the upper
skin but then you need to build up exactly same height in order to
"simulate" the skin, if you are using the template.
I did set the wing incidence before the uni reinforcing plies. The
template sits more accurate on the wing without uni.

Will, and everyone
Don't forget the incidence of the wings is more critical outboard than
it is at the root.
Set it up on the port wing and let cure as described but then set up the
second wing to be identical incidence at the flap/aileron junction. This
will help to avoid any built in roll tendency
