Check the fit of the horizontal stabilizer in its slot. Make
sure the tail is square and centred to the fuselage by
taking measurements as shown in the diagrams on the
right, but don’t glue anyhing yet.
With the horizontal stabilizercorrectly
aligned, mark the shape of the
fuselage on the top and bottom of the
tailplane using a water soluble
non-permanent felt tip pen as shown
here.
6.A Mark the top of the horizontal
stabilizer
6.B Mark the bottom of the
horizontal stabilizer
Now remove the
horizontal
stabilizer
and, using a sharp knife and a ruler
CAREFULLY cut 2mm inside the
marked lines and remove the covering
on the top and bottom of the tail as
shown. Make sure you only cut the
film and not the wood, otherwise the
horizontal
stabilizer wiil be severely
weakened.

re-check the alignment as per illustration 5.B. Excess epoxy
should be cleaned off with a rag or tissue before it cures.
Check the fit of the vertical stabilizer in its slot. Make sure
that it is glued square to the horizontal stabilizer and
fuselage

Mark the shape of the fuselage on the left and right sides
of the
vertical
stabilizer using a felt-tip pen. Now remove
the
vertical
stabilizer and, using a sharp knife & ruler,
CAREFULLY cut just 2mm inside the marked lines and
remove the covering on both sides of the fin, just as you
