This  is  a  view  of  the 

center  wing  panel,  upside-down, 
with  the  top  LE  sheeting,  shear 
webs,  and  the  two  wing  dowel 
blocks in place. 

Center Wing Panel, Top View  - 

You can see the 

bottom  center  TE  sheeting  has  been  beveled  to 
match  the  rib  contour.    When  the  top  sheeting  is 
glued  on,  the  glue  joint  formed  between  the  two 
sheets will help toughen the wing trailing edge. 

FINISH CENTER WING PANEL, Continued... 

 



Flip upside down, pin the top TE sheeting flat to your table, and support 

the LE with wood. 

 



Cut and fit two more chunks of balsa laminate to fit between the W-1 ribs 

at the trailing edge spar.  The blocks should fit firmly against the spars and the 
wing bolt plate.  Epoxy these blocks in place. 

 



Add the bottom TE sheeting (3/32" x 2-1/2"). 

 



Add  the  bottom  center  TE  sheeting  (3/32"  x  6"x  10-1/8")  to  W-1  ribs.  

Notice that the rear edge of this sheet actually extends well beyond the ends of 
the ribs.  Use the plans as a guide for the proper placement. 
 



Remove the wing from the table, flip it over, pin it down right-side up, and 

remove the temporary stick from the top of the W-1 ribs. 
 



The rear edge of the bottom center TE sheeting must be beveled to match 

the slope of the top of the ribs.  The best tool for this is to mask off most of your 
sanding block, leaving a small strip of sandpaper exposed to sand the balsa.  

Now you can add the top center TE sheeting (3/32" x 4-1/2" x 10-1/8"). 

 



When dry, flip the wing over upside-down and pin it down, this time with the top spar against the table.  Support 

the TE with a stick, then take a long careful look at the panel from all angles to be certain it is warp-free. 
 



Bevel the sub LE to match the rib contour, then glue the 

bottom LE sheeting in place. 
 



Add  the  bottom  wing  joint  sheeting,  the  center  sheeting, 

six  capstrips,  and  allow  to  dry.    Cut  holes  in  the  wing  joint 
sheeting  for  access  to  the  setscrews  in  the  channels.    Some 

builders  may  want  to  add  guide  tubes  to  help  guide  your 
balldriver to the setscrews. 
 



Unpin, trim the LE and TE sheeting.  Add the LE cap. 

 



When dry, carve and sand the LE cap to the airfoil contour.  

 



Trim all sheeting and sticks at each end, flush with the ribs. 

 



Glue the flap servo mounts in place and sheet them with balsa as you did for the aileron servo mounts.  You will 

also need to cut two holes in the bottom center sheeting for the servo leads to pass through. 

 



Now is a good time to trial fit the wing panels together.  Go ahead, stand back and marvel at all that wing area!  

If you've been careful with your construction and sanding, you may have a nice, tight fit at the wing joints.  If not, it's 
time to reach for the filler of your choice.  I'll leave the final sanding of the wing panels up to you.  You might want to 

build the ailerons and flaps first so you can take your time later and make everything fit as best you can.  Eventually, 
you will have to spend some quality time with your sanding blocks in preparation for covering.  Try to avoid sanding 
the big areas of sheeting any more than necessary.
