❑
Test-fit the wing joiner into each wing panel. It should slide easily into
each wing panel, up to the centerline you drew.
IMPORTANT When the wing joiner is installed, it should not fit tightly
into the wing panels. It should actually be slightly loose. This will ensure
that when you glue the wing joiner into place epoxy can get into the joints
between the wing joiner and the wing joiner mounting box. This will ensure
the strongest joint possible.
❑
Carefully slide both wing panels together with the wing joiner temporarily
installed (without using glue).
☞
If the wing joiner does not fit properly, use 220 grit sandpaper with a sanding block to lightly sand the wing joiner, until you are
satisfied with the fit.
❑
While holding the two wing panels together firmly, make sure that the wing panels are lined up at both the leading and trailing
edges, then look carefully at the center-section joint: the wing panels should fit together tightly with few or no gaps in the joint.
IMPORTANT If the wing panels do not fit together properly, remove the wing joiner and use 220 grit sandpaper with a sanding
block to lightly sand the edges and tips of the wing joiner, until you are satisfied with the fit. Remember, when the wing panels are
pushed together, there should be few or no gaps in the center-section joint.
step 3: joining the Wing paneLs
❑
When satisfied with the fit and alignment, pull the wing panels apart and
remove the wing joiner.
❑
Apply a strip of masking tape to the top and bottom edges of the root rib
of each wing panel.
☞
The masking tape will prevent excess epoxy from getting onto the wing
panels when you join them.
❑
Working with only one wing panel for now, apply a thin layer of 30 minute
epoxy inside the wing joiner mounting box and to only half of the wing joiner.
Make sure to cover the top and bottom, as well as the sides, and use enough
epoxy to fill any gaps.
❑
Slide the wing joiner into the wing panel up to the centerline mark, making sure to install the wing joiner so that the "V" shape is
toward the top of the wing panel. Quickly remove any excess epoxy, using a paper towel and rubbing alcohol, and allow the epoxy
to set up before proceeding.
❑
After the epoxy has set up, test-fit both wing panels together again to double-check that they still fit together properly, then apply
a thin layer of epoxy to the exposed half of the wing joiner, the inside of the wing joiner box in the second wing panel, and the entire
surface of Both root ribs . Make sure to use enough epoxy to fill any gaps.
IMPORTANT
It is of the utmost importance to the integrity of the wing center-section joint that you apply a generous amount of
epoxy to both root ribs and the wing joiner. Not using enough epoxy can result in wing failure during flight.
