Fuselage 

Prepare all parts of the fuselage. 

First put the bottom 4mm plywood part (milled slots facing up) on your (flat) 
building board. Glue in the spars onto the 
fuselage bottom (the numbers and 
positions can be taken from the drawing 
of the wooden parts in chapter 3). Make 
sure that the spars are at right angles and 
flush on both sides with the bottom part. 
Lightly sand the joint of the spars and the 
bottom on both sides. 

Next you need the two sides of the fuselage as well as two 2 x 2mm balsa strips 
and the 2mm balsa parts with the cut out 
section of the wing underside. Mark the 
positions of the spars with a pencil on the 
side parts (make a left and a right one!). 
Glue the 2 x 2mm balsa strips with an offset 
of 2 mm from the top edge onto the front 
part of the fuselage sides (the balsa strips 
will support the cover plate at a later 
stage). The 2mm balsa parts for the wing 
support must be glued flush with the top edge of the side panels (again, make 
sure that you have a left and right side!).  

Now you can glue one side to the bottom/spar construction.
