Great Planes Super Skybolt 60 Kit - GPMA0170 - Manual (Page 64)

FINAL SANDING
Check over the entire structure carefully, inspecting
for any poorly glued joints, gaps and "dings' Apply
additional glue and/or balsa filler as necessary
Then sand the entire fuselage and wing smooth
using progressively finer grades of sandpaper.
COVERING
Because it is assumed that you have had some
previous model building experience, we wont go
into detail in regard to the covering procedure
Follow the instructions included with your
covering material.
NOTE: Top Flite MonoKote was used to
cover and trim the prototype models
and we highly recommend this covering
for this model.
IMPORTANT: When covering the tail
surfaces, cut the covering before
applying i t . DO NOT, under any
circumstances, attempt to cut the
covering material after it has been
applied to the f i n and stab, except
around the leading and trailing edges
and the tip. Modelers who do this often
cut through the covering and partially
into the balsa stab. This can weaken the
stab to the point where it may fail in
flight!
GLUE ELEVATOR AND RUDDER
HINGES
D 1. Lay the rudder and elevators on the plans,
and mark on the leading edge of each part, the
locations of the hinges and the tail wheel bearing
Now use a sharp hobby knife to cut slits in the
covering at the hinge locations Trial fit the hinges
to make sure you have "found the slots which you
previously cut Transfer the hinge marks over to
the fin and stab In the same manner, slit the
covering at the hinge locations in the fin and stab
Also cut the covering away from the tail wheel slot.
D 2 Using coarse sandpaper, roughen the part of
the tail wheel torque rod that will be glued into the
rudder Then clean off the sanded portion of the
rod with alcohol or a degreasing solvent Using a
toothpick, apply a small amount of Vaseline where
the torque rod enters the nylon bearing (to prevent
glue from getting inside and locking it up)
D 3 Using a small stick, work a generous amount
of epoxy into the tail wheel hole and the nylon
bearing slot Push the control surfaces and hinges
into place, and wipe off all excess epoxy Now
check the side-to-side positioning of the control
surfaces, and glue the hinges in place with thin CA.
GLUE THE AILERON HINGES
D 1. Lay the ailerons on the plans, and mark on
the leading edge of each part the locations of the
hinges and torque rods Now use a sharp hobby
knife to cut slits in the covering at the hinge
locations Trial fit the hinges to make sure you
have "found" the slots which you previously cut In
the same manner, slit the covering at the hinge
locations in the wing Also cut the covering away
from the torque rod slots.
D 2 When building the plane with only one aileron
servo, use a small stick to work a generous
amount of epoxy into the aileron torque rod holes.
Push the ailerons and aileron hinges into place
and wipe off all excess epoxy Now carefully
position the ailerons so they have the correct
spacing at the root and tips, and glue the hinges
with thin CA*
* This is assuming you are using the type of
laminated hinges that are designed to be installed
with CA glue.
GLUE CANOPY IN PLACE
D 1 Detail the cockpit to your liking We used the
supplied instrument decal, painted the entire
cockpit flat black, and a Williams Bros #185 2-1/2"
scale sport pilot.
D 2 Poke pinholes (1/8" apart) through the
covering material in the area where the canopy will
be glued to the fuselage Lightly sand a strip
approximately 1/8" wide along the inside edge of the
canopy to help the glue stick to it Carefully clean
the canopy and the cockpit to remove any dust.
D 3 Glue the canopy in place on the fuselage We
have had good luck using RC-56 glue when
installing canopies It takes a few hours to dry, but
it is very clear and looks good in the end
