Thank you for purchasing one of the finest Sport 3-D fun-fly
models available. The Pizazz™is an outstanding model for club
fun-fly events and also is a great 3-D sport aircraft. The Pizazz
uses a conventional two-aileron setup, with separate servos
for each aileron, allowing the you to program each aileron
seperately. This is especially useful for “flapperon” configuration
of the control surfaces.
This configuration offers excellent slow speed and stall
characteristics that allow even inexperienced pilots to feel at
home. Plus, it offers aerobatic capabilities that will have your
flying buddies drooling.
To get the most out of your Pizazz, we strongly suggest using
a computer radio system. This allows you to explore the various
mixes available with computer radio systems.
With a little practice, you could be doing 3-D tricks you never
thought possible. Plus, you’ll have fun learning about your
computer radio and its capabilities.
Don’t miss out on the fun.
If you encounter difficulty in any construction sequence, please
contact one of our technicians—we stand ready to provide any
assistance we can concerning the construction of your Pizazz.

Parts Needed
• Wing (without ailerons)
• Fuselage
Tools and Adhesives Needed
• 30-Minute epoxy
• Rubbing alcohol
• Paper towels
• Hobby knife w/#11 blade
• Epoxy brush
• Mixing stick
• Felt-tipped pen or pencil
Construction of wing attachment to the fuselage begins with an
examination of the wing and fuselage. Note that each aileron will
be controlled by its own servo. You will need two servos when
you begin Section 2. We recommend a servo that has 40 oz/in
of torque or greater, such as the JR 537 servo that comes stan-
dard with JR radio systems. The JRP368 Micro Digital Servo is
also excellent choice to use in the Pizazz to save weight, but
requires a little modification for the servo rails.
Step 1. Measure the wing length to establish the center line of
the wing and mark with a pen or pencil.
Step 2. Carefully slide the wing into the fuselage opening
(the servo openings in the wing should face the bottom of the
fuselage as shown. Do not force the wing as you may crush
the structure. Some trimming may be required. You want a fairly
snug fit but not at the expense of crushing the wing structure.
Step 3. Measure the distance the wing projects on either side
of the fuselage, to make sure it is centered in the fuselage.Then
measure from each wing tip to the center of the fuselage at the
rear to be sure it is square with the fuselage. Mark the wing and
fuselage junction with a pencil on both sides of the fuselage on
the wing. This will establish the reference points of a centered
wing for the next phase, epoxing the wing to the fuselage
Step 4. Remove the wing. Use a sharp hobby knife to remove
Section 1: Installing the Wing onto the
Fuselage
7
the covering 1/8" inside the line you marked on the wing (top
and bottom). Use care not to cut the balsawood, as this will
weaken the structure. You want a wood to wood joint so the
epoxy will adhere to the fuselage/wing joint securely.
Reinstall the wing into the fuselage. Once you are satisfied with
the fit of the wing to the fuselage, and are sure it is centered, mix
up approximately 1 ounce of 30-minute epoxy.
Step 5. Apply the epoxy to both sides of the wing center, top
and bottom. To apply epoxy to top, slide wing off center and
apply epoxy from outside of fuselage on both sides. Slide the
wing back and forth to work epoxy into the joint of the
wing/fuselage.
Step 6. Wipe away excess epoxy with rubbing alcohol and a
paper towel
Step 7. Realign the wing as done in Step 3. Allow the epoxy to
cure completely before proceeding to the next step.
8
Parts Needed
• Ailerons with hinges
• Wing/fuselage
Tools and Adhesives Needed
• Instant thin CA glue
• CA remover/debonder
• Paper towels
• T-pins (one for each hinge)
Step 1. Locate the aileron pieces and hinges for the wing.
Step 2. The Pizazz™comes with high-quality CA type hinges.
Locate the CA hinges included and place a T-pin into the outside
edge of each hinge. Be sure the hinge remains centered while
installed into the control surface.
Step 3. Slide a hinge into the hinge slot of the wing for each
aileron until the T-pin is snug against the wing.
Step 4. Slide the left aileron onto the wing until there is only
a slight gap. The hinge is now centered on the wing panel and
aileron. Remove the T-pin and snug the aileron against the wing
panel. This will ensure that the hinges are centered.
Step 5. Deflect the aileron and completely saturate the hinge
with thin CA glue. The aileron’s front surface should lightly
contact the wing during this procedure. Ideally, when the hinge
is glued in place, a 1/ 32" gap or less will be maintained
throughout the length of the aileron. The hinge is constructed
of a special material that allows the CA to wick or penetrate
and distribute throughout the hinge, securely bonding it to
the wood structure.
Step 6. Turn the wing panel over and deflect the aileron in the
Section 2: Hinging the Ailerons
9
opposite direction from the opposite side. Apply thin CA glue to
each aileron hinge, making sure the CA penetrates into both the
aileron and the wing.
Step 7. Using CA remover/debonder and a paper towel, remove
any excess CA glue that may have accumulated on the wing or in
the aileron hinge area.
Step 8. Repeat this process with the right aileron, securely
hinging the aileron in place.
Step 9. After both ailerons are securely hinged, firmly grasp
the wing and each aileron to check that the hinges are securely
glued and cannot be pulled apart. To do this, apply medium
pressure while trying separating the aileron from the wing, using
caution to be certain you don’t crush the wing structure. Move
the ailerons up and down several times to “work in” the hinges
and check for proper movement.
10
Parts Needed
• Wing/fuselage
• Standard size servos with mounting hardware (2)
• Servo extension -3" (2) (JRPA092 -3" Gold)
Tools and Adhesives Needed
• Hobby knife
• Medium Phillips screwdriver
• Drill
• Drill Bit: 1/16"
• Masking tape
• Pencil
• String with weight on end
• Needle-nose pliers
Step 1. Install the recommended servo hardware supplied
with your radio system onto your servos (grommets and eyelets).
Install a servo extension lead to the servo as well. Tie the
connectors into a knot and secure the connectors with
electrical tape to prevent the servo lead connections from
becoming disconnected.
Hint: It’s always a good idea to tape or secure the servo
connectors and servo extension together to prevent the
wires from becoming unplugged inside the wing.
Step 2. Trial fit the servo into the servo opening. Depending
upon the type of servo installed, some trimming may be
required. Note that the servo is orientated so the servo arm is
closer to the trailing edge of the wing.
Step 3. With the servo in place, mark the location of the servo
screws and then remove the servo.
Step 4. Using a 1/16" drill bit, drill the servo screw locations
marked in Step 3.
Step 5. Repeat the procedure for the other servo.
Step 6. Before mounting the servos in the wing, it’s suggested
the servo lead and extension be run through the wing and out
the opening in the wing center bottom.
Note: The opening in the wing bottom will also serve as the
place where the radio and servos are mounted in the
fuselage/wing assembly.
Step 7. Tape the lead to the wing to keep it from falling back
into the opening. It may be easier if you thread one servo lead at
a time.
Section 3: Installing the Aileron Servos
11
Step 8. Securely fasten the left servo in the appropriate
opening with four of the servo mounting screws supplied with
your radio system.
Step 9. Repeat the procedure for the other aileron servo.
Note: It is recommended to have each servo connected to a
separate channel in the receiver if your radio system
has flap compatibility. This will allow for flaperon
function. Please refer to your radio system operating
instructions for selection of the flaperon wing pro-
gram so you can set up the Pizazz control surfaces
for this feature.
12
Parts Needed
• Wing/fuselage assembly
• Short rods, threaded on one end (2)
• Clevis (2)
• Control horn (2)
• Control horn mounting screws
• Clevis keepers (2 pcs of fuel tubing 7mm long)(not provided)
Tools and Adhesives Needed
• Medium Phillips screwdriver
• Drill
• Drill Bit: 1/16"
• Felt-tipped pen
• Z-bend pliers
Step 1. Locate the short rods threaded on one end, clevis, and
keepers. You will also need a control horn, control horn back-
plate, and mounting screws to mount the control horn to the
control surface. The instructions will refer to construction of just
one linkage and control horn. Assembly and installation for the
other aileron will follow this same sequence.
Step 2. Before assembly and mounting the linkages/control
horns, it’s a good idea to center the aileron servos. Connect
them to the receiver, turn on your transmitter, then the receiver.
Once the servos have moved to their electrical center, you can
position the servo control arm so that it will be approximately
90 degrees to the linkage when it’s attached. It’s important that
the mechanical adjustments are made as closely as possible
before attempting to make any electrical adjustments through
the transmitter programs.
Step 3. The control horn should be positioned so the holes
that the clevis connects onto are over the centerline of the hinge
line of the control surface. Once satisfied with the horn location
(it should be a straight line from the servo arm to the horn),
mark the location with a felt-tipped pen.
Step 4. Using a 1/16" drill bit, drill the screw holes for
mounting the control horn.
Step 5. Attach the control horn to the aileron using the screws
and the control horn backplate. Be careful not to accidentally
puncture the covering with the screwdriver.

Step 6. Thread a 2-56 clevis on the end of one of the threaded
rods. Screw the clevis on 7-10 turns. Install the clevis with wire
on the control horn into the third hole from the mounting base.
Be sure to install the clevis keeper (piece of fuel tubing) over
the clevis.
Step 7. With the linkage attached to the control horn, center the
control surface and hold the linkage wire directly over the elec-
tronically centered servo arm. Place a mark on the rod directly
over the hole (second hole from the end of arm) in servo control
arm that it will connect too.
Step 8. Make a “Z” bend in the rod at the location you just
marked.
Step 9. Insert the “Z” bend through the second hole from the
end of the servo arm. Install the clevis back onto the control
horn. Be sure to slide on the silicon clevis keeper onto the end
of the clevis.
Step 10. Repeat the process for the other aileron linkage.

Parts Needed
• Horizontal stabilizer
• Fuselage/wing assembly
Tools and Adhesives Needed
• Hobby knife • Paper towels
• Ruler • Rubbing alcohol
• Felt-tipped pen • Mixing stick
• Pencil • Epoxy brush
• 30-minute epoxy • Masking tape
Note: Before assembling the tail, be sure the elevator and the
CA hinges are removed from the horizontal stabilizer.
The hinges and elevator will be installed later.
Step 1. Measure and mark the center of the horizontal stabilizer
on its leading and trailing edge.
Step 2. On the top of the aft end of the fuselage is a saddle cut-
out for the horizontal stabilizer and vertical fin to be mounted.
Use a sharp hobby knife to remove the trim from the slots in the
fuselage. Make a center mark on the front of the saddle on the
fuselage and place the horizontal stabilizer into the horizontal
stabilizer saddle. Align the two marks you just made. Tape the
leading edge and trailing edge of the horizontal stabilizer to the
fuselage to secure it for now.
Step 2. (Continued)
Step 3. Align the horizontal stabilizer by measuring from fixed
points on the wing to the outside of the trailing edge tip of the
horizontal stabilizer. Be sure that the trailing edge of the
horizontal stabilizer stays on its center mark.
Section 5: Installing the Horizontal Stabilizer
15
Step 4. Adjust the stabilizer until you have an equal distance on
both the right and left sides of the stabilizer to the wing.
Step 5. When you’re satisfied with the alignment of the
horizontal stabilizer with the wing, carefully mark the position
with a pencil at the junction where the horizontal stabilizer
meets the fuselage, both top and bottom. The pencil should
leave a slight indentation in the covering.
Step 6. Remove the horizontal stabilizer from the fuselage.
Using a hobby knife and a straight edge, carefully cut the
covering approximately 1/16" inside the lines you drew.
Caution: It’s very important that you do not press hard
enough to cut into the wood structure, as doing
so will weaken the horizontal stabilizer.
Step 7. With the fuselage and horizontal stabilizer together on
a flat surface, check to be sure the wing and horizontal stabilizer
are parallel with each other. If adjustment to the horizontal
stabilizer saddle is necessary because the wing and stabilizer
are not parallel, carefully trim the horizontal stabilizer saddle
to adjust as necessary.
Step 8. Mix approximately 1/2 ounce (minimum) of 30-minute
epoxy to install the horizontal stabilizer to the fuselage. Using an
epoxy brush or mixing stick, spread the epoxy onto the bottom
of the horizontal stabilizer where it comes into contact with the
fuselage. Also, coat the stabilizer saddle area that will come in
contact with the horizontal stabilizer.
Step 9. Lay the fuselage onto a flat surface and position the
horizontal stabilizer onto it, making sure it’s centered and aligned
as in Steps 3 and 4.
Hint: Reference the bare wood you just exposed to re-align
the stabilizer. Use masking tape to hold the horizontal
stabilizer in place while the epoxy cures.
Note: Be sure that the horizontal stabilizer and fuselage are
assembled on a firm, flat surface and that they are
level with each other. Now re-check the alignment as
in Steps 3 and 7 and from the front to be sure the sta-
bilizer is parallel to the wing and adjust if necessary.
Step 10. Wipe off any excess epoxy using a paper towel and
rubbing alcohol. Allow the epoxy to cure fully before proceeding
to the next step.

Parts Needed
• Vertical stabilizer with rudder
• Fuselage/wing assembly
Tools and Adhesives Needed
• 30-minute epoxy
• Hobby knife
• Pencil
• Masking tape
• Rubbing alcohol
• Paper towels
• 90-degree triangle
• Epoxy brush
• Mixing stick
Step 1. Remove the rudder and hinges from the vertical
stabilizer if you have not already done so. The rudder will be
attached (hinged) to the vertical stabilizer later.
Step 2. Trial fit the vertical stabilizer onto the fuselage and
make sure it’s firmly seated down against the horizontal
stabilizer. Make sure the rear of the vertical stabilizer (where the
hinge slots are located) is aligned with the rear of the fuselage.
Note: The elevator should not be hinged to the horizontal
stabilizer at this time. It will be attached later.
Step 3. Mark the vertical stabilizer on both sides where it exits
the fin blocks.
Step 4. Remove the vertical stabilizer and carefully cut away the
covering with a sharp hobby knife just inside the lines you
marked in Step 3.
Caution: Do not cut into the wood of the vertical stabilizer
when cutting the covering, as doing so will
weaken the structure.
Step 5. Mix approximately 1/4 ounce (minimum) of 30-minute
epoxy and apply it to the vertical stabilizer where it comes
into contact with the fin block. Also apply epoxy to the base
of the vertical stabilizer where it comes in contact with the
horizontal stabilizer.
Step 6. Insert the fin onto the fuselage. Wipe away any excess
epoxy using a paper towel and rubbing alcohol.
Section 6: Installing the Vertical Stabilizer (Fin)

Step 1. Insert the hinges into the precut slots of the rudder
(do not glue at this time) and install the rudder onto the
vertical stabilizer.
Step 2. Locate the tail wheel assembly. It includes the tail wheel
wire, black nylon bearing, tail wheel, wheel collar, and screw.
Step 3. Use needle-nose pliers (or equivalent) to bend a
90-degree bend in the tail wheel wire. Remember it should
be at a 90-degree angle to the axle of the tail wheel wire.
Section 7: Installing the Rudder and
Tail Wheel Assembly
19
Step 4. Hold the tail wheel assembly up to the fuselage/rudder
in a position where it’s flush with the fuselage bottom. Note
where the wire and tailwheel nylon bearing rest in reference to
the fuselage rear and the rudder. Use a felt-tipped pen and mark
the positon of the slot where the tail wheel bearing will fit into
the back of the fuselage.
Step 5. The tail wheel’s guide wire will be installed into the
rudder. Mark the position where the hole is to be drilled into
the leading edge of the rudder for the tail wheel guide wire. It
will be located 1" up from the bottom of the rudder.
Step 6. Remove the rudder. Using a 3/32" drill bit, drill into the
exact center of the leading edge of the rudder to accept the tail
wheel guide wire as shown.
Step 7. Slot the rear of the fuselage to accept the nylon
tailwheel bearing.
Step 8. Trial fit the tail wheel assembly and rudder in place.
Deflect the rudder, making sure the tail wheel assembly turns
freely with the rudder.
Step 9. When you’re satisfied with the fit, remove the tail wheel
assembly and rudder from the fuselage. Reinstall the hinges in
the rudder using T-pins to make sure the hinges are centered as
described in Section 1.
Step 10. Mix approximately 1/4 ounce of 30-minute epoxy and
apply it both to the nylon bearing where it goes into the fuselage
and into the hole in the rudder. With the hinges in place,
reassemble the tail wheel assembly and rudder.
Hint: A toothpick applicator may be helpful in getting the
epoxy into the hole.
Step 11. Make sure the rudder is aligned properly (up & down)
to the fuselage and rudder. Wipe away any excess epoxy with
a paper towel and rubbing alcohol. Allow the epoxy to cure
completely before proceeding.
Step 12. With the rudder and tail wheel assembly installed,
apply thin CA to the rudder hinges on both sides, using the
same techniques outlined in Section 2. Be sure to remove the
T-pins before applying the CA. There should be a minimal gap
between the rudder and vertical stabilizer.
Step 13. Wipe away any excess CA with CA remover/debonder.
After the hinges are dry, check to make sure they are securely in
place. Try to pull the rudder from the vertical stabilizer. Use care
not to crush the structure.
Step 14. Slide the tail wheel itself onto the tail wheel wire.
Next slide the wheel collar on the wire and tighten the screw
in the wheel collar. Place a drop of threadlock on the screw
to secure the collar in place.
Note: The tail wheel should rotate freely with only a small
amount of side play. Check to be sure the rudder and
tail wheel operate smoothly.
Parts Needed
• Fuselage/wing assembly
• Elevator
Tools and Adhesives Needed
• Thin CA glue
• CA remover/debonder
• Paper towels
• T-pins
Step 1. Locate the elevator and hinges. Trial fit the elevator into
the proper position on the horizontal stabilizer using the same
hinging technique used in Section 2. Remember to remove the
T-pins before applying the CA glue. Also, make sure the tail
wheel is free to move its full range.
Step 2. With one elevator half aligned (left and right), apply thin
CA glue to the hinges on both sides. Wipe away any excess CA
with CA remover/debonder and a paper towel.
Note: Try to maintain a minimal gap throughout
the length of the hinge line.
Step 3. After the hinges are dry, check to make sure they are
securely in place. Try to pull the elevator from the horizontal
stabilizer. Use care not to crush the structure.
Step 4. Repeat the previous procedure for the other
elevator half.
Step 5. Flex the elevators up and down several times to
“work-in” the hinges and check for proper movement.
