Thanks everyone - I think I've got it cracked now - right wing first, tape
it.
Then, the big thing I've learnt is to feel inside the battery rack below
the
spars. I can now tell, by feel whether the second wing is too high or too
low
and knowing that makes all the difference.

I put reference marks on the spar butt ends and inside the fuselage that indicate when the correct dihedral angle is achieved. I also using my index finger to feel for a mismatch between the main pin bushings while adjusting the height of the fuselage jack (start low and gradually go up). You can feel even the slightest misalignment.
