Sand down the rear center section balsa blocks for the wing bolts to match the rib profile on
either side of them. Laying some tape on the ribs will help keep you from sanding into the ribs
themselves.
27.
Lightly sand the entire wing with 320 and 400 grit sandpaper. The smoother the sanding job,
the better the covering will look.

It is a
VERY GOOD IDEA
to run a string from the servo box up through the servo wire hole in
the center of the wing, so you can fish the servo wire out the wing after it is covered. Tape the
string in place just to the inside so you can get to it after cutting out the holes in the covering.
Section 3: Assembling the Ailerons
1.
Build both ailerons at the same time to make sure you make a LEFT and RIGHT aileron.
2.
Press the 3/32” aileron ribs into the 1/16” aileron sheet as shown below. The center ribs are
made up of a 1/16” balsa rib between 2 of the 3/32” ribs. Do NOT glue them in place yet.
3.
Press the 1/16” top front part in place as shown below. Make sure the aileron is flat and
secure the parts in place with thin CA.
