bottom that you marked along the
right and left sides of the fuse.
Step 5
Use a new # 11 blade and gently cut
through the ultra cote. See Figure 7.
There are two layers, cut through the
top layer first and remove it. You
have probably cut through the
second layer. If not you may cut
through the second layer. Be very
careful not to cut into the balsa
sheeting as this will weaken the
structure of the Horizontal Stab as
the skin sheeting is important to its
structural integrity.

Step 6
Use your iron to seal down the Ultra-
cote where you removed the center
section before you make the final
attachment.
Step 7
Re-insert the H. Stab into the
fuselage. IMPORTANT: Check the
measurements again, to make sure
the H. Stab is square. Before you
make the final attachment of the H.
stab to the fuse, you must check to
see that the H. stab is parallel with
the wing.
To do this, you may sight down the
fuselage from the rear.
See Figure 8. Make sure you are
looking straight down the middle of
the fuse.

plane color scheme

Step 8
Sight both sides of the H. stab and
compare with both sides of the wing.
If one side is lower and the other
higher, you will need to shim so both
the H. stab and the wing halves are
parallel. Now you are ready to glue
in place.
Step 9
Use thin CA and do this couple of
times. Position the plane in knife
edge attitude to make sure CA is
soaking into the slot. At the end, use
thick CA to fill up the gap. Try to
avoid accelerator until the last stage
that you are using thick CA.
Step 10
Now it’s time to do the elevators.
The elevator halves will be
connected via a CF tube.
