For longevity we will use a wood dowel
sunk into the hard points in the ailerons,
with a 3mm or 6-32 standard stud
tapped into the hard points. This will give
you more options on the BB clevises
manufactured by MK™ and Central
Hobbies™. A slack free linkage, with
little to no wear, is a must for precision
and longevity. This will completely pre-
vent flutter and unwanted movement
during flying. So, for this reason, I rec-
ommend you do not use the clevis arm
provided in the kit for aileron linkage,
unless you're building an electric ver-
sion.
A large 4-stroke engine can be very
abusive to the surfaces. The tighter you
can keep the play in the linkage, the
better the wear and precision in flying.
And again, to prevent wear, we need to
add a 4mm-4mm rib insert, around the
inside of the wing root flashing, so we
can add wing saddle tape to prevent
noise and wear.
#1 Cut some 4mm-4mm light stick
balsa, the length on the root opening,
next. Using CA or epoxy, carefully fit and
glue the inserts into the root rib flashing,
using small clamps/cloths pins; when
dried, shave it flush to the outer surface
edge. Test fit the wing to the fuse, and
adjust the root rib flashing to fit the fuse
correctly; when satisfied, add the saddle
tape.
# 2 Glue a square piece of wood, drilled
in the center, over the wing mount bolts
flush to the root rib saddle tape edge;
this will be a stop gauge to prevent over
tightning of the wing mounting thumb
nut, when tightening the wing to the fuse
side.
#3 Install the aileron servo in the wing
and measure a ninety-degree angle from
the servo arm. Mark the line on tape, to
the aileron clevis mounting area.
