To Any/All builders,

Before bonding the wing profile jig on the upper part of the wing (when
installing flaps on the wings), is it assumed that the upper wing skin
thickness should simulated with a suitable spacer such as popsicle sticks or
such?  The jig, when placed on the wing root, lines up with the indentation
where the top wing skin would be, at the rear of the wing. I placed lately
taped-in sticks at the rear of the wing, where the jig will be set, to
simulate the top skin, in anticipation.  The difference between both ways is
only in the 1-2 mm area, but anyhoo..  Including spacers looks like it would
-slightly- increase the reflex of the flap. Just trying to get a feel for
what others have done, or interpreted this move. A short search on matronics
did not eek out any results.

Thanks in advance,
Greg
