WING ASSEMBLY:

From the kit contents locate the right and left wing panels and the
plywood wing joiner.  You will also need epoxy glue, epoxy mixing
supplies, paper towels, and rubbing alcohol. 

1) For  maximum  strength,  we  recommend  using  SIG  Epoxy

Glue for joining the wing panels in this step.

a) Trial  fit  both  wing  panels  together,  without  glue,  on  the 

plywood  wing  joiner  to  familiarize  yourself  with  the 
assembly.  Then, take back apart.

b) Mix up a small amount of epoxy glue.  Use a wire or stick

to quickly coat the inside of the wing joiner slot in the end of the
right  wing  panel.    Also,  coat  the  right  half  of  the  plywood  wing 
joiner with glue.  Push the plywood wing joiner all the way into the
slot in the right wing panel.  Hold the wing joiner in place until the
glue dries, wiping off any excess glue that oozes out of the joint.

c) Mix up a batch of epoxy glue.  Use a wire or stick to coat

the  inside  of  the  slot  in  the  end  of  the  left  wing  panel  with  glue.
Also, coat the stub of the plywood wing joiner, that is sticking out of
the  right  wing  panel,  and  the  bare  wood  end  ribs  of  both  wing 
panels.  Then, put the wing panels together.  Squeeze the panels
tightly together, aligning the leading and trailing edges of the wing
panels with each other.  Wipe off any excess glue that oozes out of
the joint with a paper towel soaked in rubbing alcohol.  Hold or tape
the wing panels in proper position until dry.

NOTE:

If  possible,  get  someone  to  help  you  with  this  step.    An

extra set of hands makes the job much easier.  While one person
holds the two wing panels together in correct alignment, the other 
person  can  clean  off  the  excess  glue  and  tape  the  wing  panels
tightly together.

2)

Optional  Step:

A  3/8"  wide  strip  of  white  covering 

material  is  supplied  to  cover  the  center  joint  of  the  wing  panels.
Remove  the  clear  backing  from  the  covering,  and  then,  iron  the
strip  in  place.    This  covering  strip  has  no  structural  purpose,  it 
simply gives the wing a more finished look.

3) Test fit the assembled wing onto the fuselage.  The plywood

tab that sticks out from the center leading edge of the wing fits into
a cutout in the front fuselage former.  Make sure the wing slides the
entire way forward, snug against the back of the fuselage former.
At the rear, align the wing with the fuselage, and then, use the two
4-40  x  1"  nylon  wing  bolts  to  secure  the  wing  in  place  on  the 
fuselage.  After checking the fit, remove the wing for the next step.
