5.

Remove the wax paper, then lightly mark the

outline of the fi n on the fuse top and the stab with
a ballpoint pen.

6.

Make the

fi n braces

from the remaining 1/4"

balsa triangle stock. Make the braces 4" to 4-1/2"
long and bevel the ends. Position the braces on
the stab and trace their outlines on the fi n and stab

with a ballpoint pen.

Covering

Prepare for Covering

1.

Inspect the entire model for glue joints that

don’t look strong and reinforce them with medium
or thin CA.

2.

Remove the fi n (with the dorsal fi n) and stab

from the fuse. Final-sand the tail surfaces with
320-grit sandpaper being careful not to break any
of the tail ribs or “thin” the balsa too much in any
one area.

3.

Slightly round the top and bottom corners of

the fuselage and the triangle stock “windows” with

your bar sander and 220-grit sandpaper. Sand the

fuselage so it is smooth and even. Fill all dents,

scratches and imperfect glue joints that may show
through the covering with HobbyLite fi ller.

4.

Use medium CA to glue the die-cut 1/8"

plywood

tail skid

and balsa triangle reinforcements

to the bottom of the fuselage or glue the skid in
position after you cover the fuselage.

5.

Test fi t the wing in the fuselage and adjust the

front and rear “windows” if necessary so the wing
will fi t between them.

Covering Tips

If this is the fi rst time you have covered a
model refrain from attempting a complicated
trim scheme.

Add stripes, graphics and various

designs to your Butterfl y cut from different colors
of MonoKote fi lm, then iron them directly over the
