Now just clean up the trailing edge of the flaperons as they often have a lip along the
rear edge. Use an electric tool first and finally a wooden sanding block about 1 meter long
to get a smooth and perfectly straight finish.
Mounting the wings
Once the wings have been completely prepared, you can begin mounting them on to the
fuselage. You will definitely need at one more person to help you with this step.
First you need to ground down the adhesive rim that exists between the upper surface of
the wing spar and the wing's upper surface. Continue grinding until the wings spar and
upper surface form a right angle (see pictures below). NOTE: it is VERY important that
you DO NOT grind into the surface of the wing or into the actual wing spar. Focus on
grinding the adhesive rim ONLY.
