Before starting you may wish to very lightly 
sand down all the flat surfaces of the parts if 
you want to have a smooth finish. It’s easier 
to do this initially, otherwise the ribs will get 
in the way of sanding when complete.  

 

 

When removing parts from the sheets, identify where the cut line is sectioned and cut that part 
with a sharp pointed hobby knife. The parts should be able to be removed easily. Never twist or 
bend the parts back and forth to remove them as this will damage the parts. Instead cut around 
the parts as necessary to easily remove them.  

Remove the ribs from the hardwood sheet and glue these in place to  the wings. 
Note: If you are choosing to put any decals on your wings and in particular on the underside, it 
will be difficult to attach them once the ribs are glued in place. You may wish to attach the decals 
before you glue the ribs in place. If doing so, glue in all the ribs except the ones which will go 
directly over the decals. This will give the wings their curve before attaching the decals. The 
decals can then be applied to the curved wing and they will sit flat on the wing surface. Once the 
decals are attached, go ahead and glue the final ribs in place. See image below to identify the 
leading edge before gluing the ribs in place. Also lay your wings out with the centers together and 
ensure you don’t make two left or two right wings by gluing the ribs to the same side of the wing 
on each side. 

 

 

 

 

 

 

It is a good idea to use Model Masking Tape 
to hold down the ribs while they dry.
