❏ 4. With the radio switched on, move the throttle trim and
control stick to the fully closed position by pulling them back
(or downward) all the way. Manually close the throttle on the
carburetor completely. Tighten the Cap Screw on the screw-
lock pushrod connector. Check throttle operation with the
radio and make adjustments to the linkages as necessary
for smooth operation. Use the appropriate holes in the servo
and throttle arms to provide the correct amount of throttle
movement and to prevent the servo from binding at its end
points. Once everything is adjusted, install a brace near the
servo for the outer pushrod tube.

FINAL ASSEMBLY

Windshield Installation

❏ 1. Carefully trim the Windshield along the cut lines with
®
scissors or Lexan shears. Test fit the windshield on the fuse
as you proceed, making small adjustments as required for
a good fit.
❏ 2. If you wish to paint the windshield, test the paint on a
sample of the canopy material to make sure the paint is
compatible. Straight out of the spray can, Top Flite
LustreKote ® is not recommended for painting the clear
plastic your windshield is made from and will eventually curl
it. But, if you have an airbrush, it is possible to paint your
windshield with LustreKote; however, you must use the
following procedure. Spray an ounce or two of LustreKote
through a tube (such as a large drinking straw or a brass
tube) into a container. Let it sit for about an hour or two to
allow the damaging elements to "boil off." Using an air
brush, you may now spray your windshield with your
specially prepared LustreKote. For airbrushing, we
recommend thinning LustreKote with lacquer thinner. If you
prefer to spray your windshield frame directly from a spray
can, we have had success with Pactra Formula-U and
Chevron paint. Always test your painting methods on
leftover plastic before you try it on your model!
❏ 3. Paint the exposed wood behind the windshield with
black paint. Install pilots if so desired. You can use Top Flite
LustreKote without any special preparations to the paint or
the model. Just make sure to mask off any areas you do not
want painted.
❏ 4. Roughen the bottom 1/8" [3mm] of the inside
windshield edge, being careful not to scratch any exposed
areas. Glue the canopy into position with 6-minute epoxy or
R/C-56 glue.
❏ 5. Trim the Side Windows so 1/32" [.8mm] remains for
the windows to rest on the inside of the fuselage. Because
the windows fit recessed into the fuselage from the inside,
this lip must remain on the windows. Roughen the outside
edges of the windows and glue them inside the fuselage
with 6-minute epoxy or R/C-56 glue.

Strut Installation

❏ 1. Attach the wing to the fuse with two 1/4-20 x 2" nylon
bolts. Place the Struts into position, taking note of the
"airfoil" shape of the struts.
❏ ❏ 2. Drill a 1/8" [3mm] hole where the strut will attach to
the fuselage and one in each of the ends attaching to the
19
