6) When you are satisfied with the alignment,
hold the stabilizer securely in place with masking tape,
but do not glue it in place at this time.
MOUNTING THE HORIZONTAL STABILIZER
q
7) With the stabilizer held firmly in place, use a
pen and draw lines onto the stabilizer where it and
the fuselage sides meet. Do this on both the right and
left sides on the bottom of the stabilizer.
q
8) Remove the stabilizer from the fuselage. Us-
ing the lines you just drew as a guide, carefully remove
the covering from between them using a modeling
knife. See photo # 10 below.

When cutting through the covering to remove
it, cut with only enough pressure to only cut
through the covering itself. Cutting into the balsa may
weaken the stabilizer.
q
9) Using a modeling knife, carefully remove the
covering from the top of the stabilizer mounting sides
on the fuselage.
Removing the covering will allow a better bond
between the two parts. If the glue joint between
the fuselage sides and the stabilizer is not adequate, it
could lead to stabilizer failure during flight.
q
10) When you are sure that everything is aligned
correctly, mix up a generous amount of Kwik Bond
30 Minute Epoxy. Apply a thin layer to the mounting
area on the bottom of the stabilizer and to the top of
the stabilizer mounting sides on the fuselage. Set the
stabilizer in place and realign. Double check all of
your measurements once more before the epoxy cures.
Hold the stabilizer in place with masking tape and
remove any excess epoxy using a paper towel and
rubbing alcohol.
INSTALLING THE TRIANGLE STOCK
q
11) Using a modeling knife, remove the cover-
ing that overlaps onto the inside edges of the two
pieces of triangle stock.
q
12) Working with one piece of triangle stock for
now, align it in the joint between the bottom of the
stabilizer and the fuselage side. When it's properly
aligned, the triangle stock should be centered between
the leading edge and trailing edge of the stabilizer.
See photo # 11 below.

the stabilizer with the centerline marks drawn on the
fuselage. When those are aligned, hold the stabilizer
in that position using masking tape. Align the hori-
zontal stabilizer with the wing. When viewed from
the rear, the horizontal stabilizer should be level with
the wing. If it is not level, use 220 grit sandpaper
with a sanding block and sand down the high side of
the stabilizer mounting platform until the proper align-
ment is achieved. The tips of the stabilizer should
also be equal distance from the tips of the wing. See
figures # 1 and # 2 below.
q
13) When satisfied with the alignment, hold the
triangle stock in place and draw around it using a pen.
q
14) Remove the triangle stock and use a model-
ing knife to remove the covering from inside the
outline you drew.
