Right-hand Outer Wing Panel  - 

There is still some 

"give" in the structure at this point, so the plans are 
necessary  to  ensure  that  the  main  spar  is  perfectly 
straight.    The  TE  is  positioned  off  the  edge  of  the 
table  so  that  the  balsa  sheet  can  overhang  above 
and below.  Each piece of sheeting that is added will 
help lock the panel into its final shape. 

 1    FINISH OUTER WING PANELS       >  

 
 



Sand the back edge of the panel as shown in the diagram.  Use a 

long sanding block and straightedge to be sure the trailing edge is  straight 

along its entire length. 
 



Pin or weight down the panel over the plans.  Make certain 1) the 

main spar is straight, 2) the trailing edge is hanging off the edge of the table, 

and 3) the trailing edge isn't bowed up or down.  Use shims if necessary to 
force the TE of the panel to be absolutely straight. 
 



Glue on the 1-3/8" strip to the back edge of the wing.  

There should be a little overhang, top and bottom. 
 



When  dry,  trim  the  overhang  (top only).    Add  shear 

webs (vertical grain) to the rear spar, four places. 

 



Add the top TE sheeting  (3/32" x 2-3/4" x 36").  Note 

that the sheeting covers only half (1/4") of the rear spar. 
 



Add the final six shear webs to the main spars, two in 

front of the main spar and four in the back. 
 



Sand the top edge of the sub LE to match the airfoil 

contour in preparation for the leading edge sheeting. 

 



Glue the top LE sheeting in place.  Again notice the 

sheeting  should  cover  only  half  the  width  (3/8")  of  the  main 
wing spar.  I like to apply yellow glue to the ribs first, then glue the sheeting to the sub LE with CA, and finish the 

sheeting with more CA along the spar.  It's important, after gluing the LE, to "massage" the sheeting towards the spar 
by wiping it with your hands from front to rear.  This will keep the sheeting in firm contact with the ribs, although you 
may still want to add some weights to the sheeting until the yellow glue dries. 
 



Glue your top wing joint sheeting in place.  It will have to be trimmed to fit between the LE and TE sheeting. 

 



Add the top capstrips, eight places. 

 



Remove from the table, trim the trailing edge sheeting, and re-glue your new joints with medium CA. 

 



Decide what type of hinges you're going to use.  I used Sig's large pinned hinges, and didn't feel the need to 

add any "beef" to the wing structure to accomodate them.  If you plan on using something different, like Robart's large 

hinge points, you should definitely add some balsa blocks to the top TE spar at each hinge location. 

See "About the Hinges" on page 24.

 

 



Flip upside down, pin the top TE sheeting flat to your table, and support the LE with wood (photo next page). 

 



  Add the bottom TE sheeting (3/32" x 2-1/2" x 36").
