ALIGNING THE BELLY PAN

4) With the wing securely attached to the fuse-
lage, trial fit the belly pan to the bottom of the wing.
The sides of the belly pan, at both the front and the
rear, should be flush with the sides of the fuselage.
The angles at the rear of the belly pan should also be
flush with the angles of the fuselage bottom.
You might find that you will need to trim the
front edge of each lip on the belly pan where
they meet the leading edge of the wing. This will
allow the lip to fit flush with the wing surface with-
out deforming the rest of the belly pan.
5) When satisfied with the fit, hold the belly pan
in place on the wing using a couple of pieces of mask-
ing tape. See photo # 9 below.

6) With the belly pan held firmly in place and
aligned properly, use a pen and outline onto the wing
surface the outside edge of each of the two lips on the
sides of the belly pan.
7) Remove the belly pan. Using the lines as a
guide, use a modeling knife and remove about 1/4"
of the covering from the inside edge of each line.
Removing the covering will allow a stronger
bond between the belly pan and the wing when
the belly pan is glued in place.

INSTALLING THE BELLY PAN

8) Mix up a generous amount of Kwik Bond
30 Minute Epoxy. Apply a thin layer of epoxy to
the bottom portion of each of the two plastic lips on
the belly pan. Carefully set the belly pan back in
place on the wing and align it as you did previously.
Hold the belly pan firmly in place using strips of
masking tape.
9) Remove any excess epoxy using a paper
towel and rubbing alcohol. Allow the epoxy to fully
cure before proceeding.
10) Using a pen, mark the locations on the bot-
tom of the belly pan of the two wing hold down
screws. The two holes will be located 1/2" in from
the belly pan sides and 1-1/8" forward of the bottom
rear edge of the fuselage.
11) Using a 3/8" drill bit, drill two holes
through the belly pan to access the wing bolts. See
photo # 10 below.

PARTS REQUIRED
{1} Horizontal Stabilizer w/Elevator & Hinges

ALIGNING THE HORIZONTAL STABILIZER

1) Remove the elevator from the horizontal sta-
bilizer and set it aside for now.
2) Using a ruler and a pen, locate and mark the
centerline of the horizontal stabilizer, at the trailing
edge, and place a mark. Use a triangle and extend
this mark, from back to front, across the top and bot-
tom of the stabilizer.
3) Using a modeling knife, carefully remove the
covering from both sides of the fuselage that covers
the stabilizer slot precut in the rear of the fuselage.

4) Slide the stabilizer into the slot. The stabi-

the slot.
