19. Securely anchor the pushrod guide tubes to F-4
using cross-braces cut from scrap 1/8" balsa.
20. Attach the throttle pushrod (and nose gear steering
pushrod) to the throttle and rudder servo arms. NOTE: We
recommend using DuBro "E-Z connectors" (or similar) for
these hookups, for ease of installation and adjustment.
21. If you are using retracts, install your retract servo at
NOTE: Some modelers prefer to tint their canopies for a
more subtle and realistic effect. You may tint your canopy by
immersing it in a concentrated mixture of Rit Liquid Dye and
hot tap water. The colors blue. black, brown and dark green
work well. Remove the canopy after 5 minutes and rinse it off
to check the amount of tint. The hotter the water and the
longer you leave it in the dye solution the darker it will tint.
CAUTION: Do not heat the dye water above tap water
temperature, as this could deform the canopy.
this time.
1. Using a scissors, carefully cut the canopy just below
the trim line.
22. Hook up your radio system and test the operation of
all controls.
FINISHING
ADDITIONAL FUELPROOFING
If you have not already done so, make sure the entire
engine compartment is completely fuelproof. Also fuelproof
any wood that will not be covered and which may be exposed
to glow fuel residue, such as the landing gear block slots and
the wing saddle. Use epoxy thinned with alcohol, polyester
finishing resin or fuelproof paint.
2. Trial fit the canopy onto the fuse, pressing into
place. Trim as necessary for a good fit. NOTE: The trim line
on the canopy is approximate. Your canopy trim will vary,
depending on how you sanded the fuselage. It may be neces-
sary to do some additional sanding of the fuse near the front
of the canopy, if the canopy does not fit properly.
3. Sand the edges of the canopy with 320 grit sandpa-
per. It is important that the canopy does not have any cracks
along the edges, as the engine vibration could cause them to
spread.
SEAL OFF COCKPIT
If you leave any openings through the fuse top into the
cockpit area, there is the possibility of getting dust on the
inside of the canopy, which is almost impossible to remove.
Therefore, you should seal all openings to the inside of the
cockpit, and paint all exposed balsa to prevent loose wood
particles.
NOTE: Do not glue the canopy in place until after you have
covered your model.
BALANCE THE AIRPLANE LATERALLY
PREPARE THE CANOPY
NOTICE: The clear canopy in this kit may have a thin
blue protective film on both sides. Peel off this blue
film before attempting to tint or glue the canopy.
SPECIAL NOTE: Do not confuse this procedure with
"checking the C.G." or "balancing the airplane fore and
aft". That very important step will be covered later in the
manual.
Now that you have the basic airframe nearly completed,
this is a good time to balance the airplane laterally (side-to-
side). Here is how to do it:
