Hi Bud,
Yep, my plan is to use one popsicle stick plus a layer of tape as a wing
skin simulate before finalizing the flap hinge positions.
Thanks, I will use these techniques when setting the wing incidence (not
too far away from it, now). They will be quite useful.
thankyou,
Greg

Greg,
I find that measuring the wing skin thickness and using spacers to be the
idea way to set the wing incidence when using the incidence board. You will
notice that the wing skin has about a 1/4 inch of foam but that foam ends
before the root rib. The skin is about 6 layers thick at the root or about
a popsicle stick. The big thing is to get both wings the same. Get anal
about it and use a good digital level, the same incidence board, a spacer
set about 2 inches in front of where the rear pin goes, and I even hold the
level with the digital screen facing the same way at the same exact position
on the incidence board. Then, before I glue it final, I step back and
check by eye, the lower skin of each wing of the aircraft from behind to
verify that the bottom of the wings both are at the same angle. See my
website for trimming the Europa.

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.
