Wing  Panel,  Upside  Down  - 

The  idea  here  is  to 

position  the  top  TE  sheeting  flat  against  the  table.  
This requires a support at the front; I used a piece of 
lumber  that  was  lying  around.    Worked  well!    You 
can  see  the  TE  sheeting  overhangs  at  the  rear.    It 
will be trimmed later. 

Aileron  Servo  Mount  - 

with  balsa  sheeting 

ready to be glued in place.  Note the extra-long 
cutout  in  the  balsa.    The  servo  flanges  should 
sit flat against the lite-ply, not the balsa. 

Finished Outer Wing Panel - 

The leading edge cap 

has been carved and sanded, and all of the sheeting 
has  been  carefully  trimmed.    Note  the  fillets  in  the 
corners  of  the  wing  joint  sheeting.    Not  necessary, 
but it adds a touch of class 

High-Tech  Sanding  Tool 

for  sanding  the  fillets  to  a 
uniform curve.  This is the 
cardboard core of a roll of 
shipping  tape.    Simply   
glue sandpaper to one half 
of  it,  and  use  the  other 
half  as  a  template  for 
drawing  the  curves  on 
your  sheeting.    Draw  the 
curve, cut, and sand! 

FINISH OUTER WING PANELS, Continued... 

 



Unpin the TE, then pin or weight the panel down on the table, 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.  

This is your last chance to build a flat wing panel; once the remaining sheeting is glued in place, your wing panel will 
be locked into its final state.  In case you're wondering, the SFK doesn't have or need washout.  Try for zero warps! 
 



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

the bottom LE sheeting in place. 
 



Trim the bottom wing joint sheeting to fit, then glue it 

in place.  Add eight capstrips and allow to dry. 

 



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

When dry, carve and sand the leading edge cap to the airfoil 
contour.  Take your time with this step and try for a consistent 

shape along the entire length of the wing panel. 
 



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

 



Glue  the  assembled  aileron  servo  mount  in  place.  

The  sides  of  the  lite-ply  mount  should  fit  snug  between  the 
ribs and spars.  You may have to round off the corners a bit 
to clear glue fillets in the wing structure. 
 



Sheet  the  surface  of  the  mount  with  3/32"  balsa.    The 

edges  of  the  sheeting  will fit  between  the  capstrips.  Be  sure  to 
make the cutout in the balsa oversize at the front and rear so the 
servo flanges will seat against the lite-ply mount. 

 



Add the 3/8" wingtip support followed by the balsa wingtip.  

I'm  sure  you've  noticed  by  now  that  my  prototype  features  the 
optional STOL wingtips.  To me, they just look "right" on a model 

like this, but they do represent a lot of extra sanding and shaping.  
Like so many things with this model, it's your choice!
