Safety in Flying
This is NOT a toy! It is a very high-performance RC airplane capable of high speeds and extreme maneuvers. It should
only be operated by a competent pilot in a safe area with proper supervision.
ONLY fly your aircraft in a safe, open area, away from spectators and vehicles–and where it is legal to fly.
NEVER fly over an unsafe area, such as a road or street.
Never fly too close to yourself or spectators.
Never run your motor inside a house or building with the propeller attached – Remove the prop for safety.

Before Starting Assembly
Examination
Unpack your airplane and examine the components. Check for damage of any kind. If you see any damage, please
contact Value Hobby immediately.
Covering
Your airplane was packed in plastic at the factory without any wrinkles in the covering. You may notice some
wrinkles now; more likely, you will notice a few in a day or two or the first time you take the plane out to the flying
field. These wrinkles are the result of wood shrinkage and/or expansion. Balsa wood changes size and shape slightly
as it is exposed to varying humidity in the air. This is a natural property of balsa wood. As your airplane adjusts to the
weather in your part of the world, wrinkles may appear and disappear. Wrinkles may be removed with the gentle
application of heat to the covering material on your airplane. The best tool to use is a hobby heat gun. Apply the
heat gently: the covering material will shrink as you apply the heat, and this will remove the wrinkles. BE CAREFUL!
Too much heat applied too quickly can damage the covering, either by causing it to pull away from the wood at
seams and corners or even by melting it. The covering will shrink at low temperature with patient application of heat.
Wrinkles in the covering DO NOT affect flight performance.
Remove the canopy before attempting to use heat on your covering! The canopy is made of thermo-activated plastic
and WILL deform with the application of heat. Do not apply heat to the canopy.
If you need to clean your airplane, we recommend using a damp towel. The paint used on the canopy and cowl is
not safe for all cleaners. In particular, DO NOT use alcohol on these parts, it will remove the paint.

Install the Ailerons
Step 4: Adjust the aileron so there is a small gap between
the LE of the aileron and the wing. The gap should be
about 1/64-inch or just wide enough to slip a piece of
paper through.
Step 1: Drill a 1/16-inch hole into the center of each hinge
slot in the aileron and wing panel. Trim the covering away
from each hinge slot to ensure that the hinges will be
properly glued in place.
Step 5: Apply six drops of thin CA to the top and bottom of
each hinge. Do not use accelerator in the hinging process.
The CA must be allowed to soak into the hinge naturally.
After the CA has cured, flex the surfaces several times to
break in the hinges. Pull on both surfaces to make sure the
hinges are secure.
Step 2: Test fit a CA hinge into each of the hinge slots. If
necessary, enlarge the slots with a hobby knife. When
satisfied with the fit, place the hinges into the slots. Push a
pin through the middle of each hinge to keep them
centered.
Repeat steps 1-5 for the other wing panel.
Step 3: Join the aileron to the wing panel and remove the
pins from the hinges. Center the aileron on the wing.
7
Install the Aileron Servos & Pushrods
ENLARGE TO
2mm
Before installation, confirm that the servos you will be
using will properly fit in the servo opening. Make
adjustments as necessary for your servos. The pre-cut
servo openings on this airplane will fit most standard size
servos.
CUT O FF
UNUS ED ARM
Step 3: Securely tie the string from inside the opening for
the aileron servo to the end of the servo extension. Pull
the servo wire and extension through the wing.
Step 1: Installing the servos in the wing will require the
use of a servo extension wire for each aileron servo. One
Y-harness connector is also required and is used to allow
the aileron servos to plug into one slot in your receiver.
You may also have a computer radio that allows you to
plug the servos into separate slots and then mix them
together with the radio transmitter. If you choose to mix
them together with the radio rather than a Y-harness,
refer to the manual for your particular model radio system.
Step 4: Temporarily position the aileron servo into the
servo bay. Install and remove a servo mounting screw into
each of the four holes. Apply a drop of thin CA into the
holes to harden the wood. After the glue has hardened,
install the servo into the opening. Cut three arms from a
four-armed servo arm (arms may need to be purchased
separately). Center the servo with your radio system and
install a servo arm parallel to the aileron hinge line as
shown.
Step 2: Attach the servo extension to the aileron servo and
secure it with heat shrink tubing. The tubing can be
shrunk around the connector with a heat gun or micro
torch. If your aileron servo has tabs molded into the case
for mounting the servo on its side, they must be cut off in
order for the servo to fit into the servo bay in the wing
panel. Follow the instructions included with the servo for
cutting the tabs. Install the eyelets and grommets included
with the servo.
8
Step 5: Locate a Ф1.8 x 110mm (4.3 in) pushrod wire
threaded on one end. Screw a nylon clevis onto the rod.
Connect the clevis to the second hole on the control horn
Finish the wing panels
Step 1: Without using any glue, test fit the wing halves
with the wing joiner. Make sure the halves fit together
well. If there is a problem, look for obstructions such as
glue bumps or wood slivers inside the wings. Make any
adjustments necessary to get a good fit.
Step 6: With the pushrod wire is 90-degrees to the hinge
line and holes in the control horn aligned with the hinge
line, use a drill bit to drill the mounting holes for control
horn.
Install the control horn to the aileron using two
M2*20mm (0.8 in) screws and one backplate.
Step 2: Mix a generous amount of 30-minute epoxy. Pour
the epoxy into the joiner opening on the wing. Make sure
the epoxy is distributed all the way around inside the
wings. Use an epoxy brush to coat the root ribs of both
wings and one half of the joiner all the way around. Insert
the epoxy-coated half of the joiner. Wipe away excess
epoxy as it is forced out.
Step 7: With the control surface centered, tighten the
screw to secure the pushrod to the servo arm.
9
Step 3: Coat the protruding end of the joiner all the way
around with epoxy.
Join the other wing, and press the two halves together,
allowing excess epoxy to drip out as you go.
When the wings come together, wipe away excess epoxy
that is squeezed out, and then use a C-clamp and several
strips of masking tape on both the top and bottom of the
wing to tightly hold the two halves together. If epoxy
continues to work out of the wing under the tape, remove
one strip at a time and wipe off the epoxy, then replace
with another strip of tape. Do not disturb the wing until
the epoxy has hardened.
Step 6: Trim the covering just inside your lines. Wipe
away the lines with alcohol and glue the wing bolt plate to
the wing.
Continue the wing bolt holes through the wing bolt plate
with a 1/8" [3.2mm] drill bit. A wood backer piece while
drilling will help ensure clean-edged holes in the wing bolt
plate.
Step 6: When you are finished installing electronics inside
the fuselage, you can install the wing onto the fuselage
using two machine screws and two flat washers.
Step 4: Locate and remove the covering from the wing
bolt holes near the trailing edge of the wing.
Step 5: Align the wing bolt plate over the holes on the
underside of the wing. With the wing bolt plate centered
over the holes, use a sharpie pen to trace around the plate
onto the wing.
10
Install the Stabilizer
Step 1: Locate the horizontal stabilizer slot under the
covering on the tail section of the fuselage by lightly
pressing with your finger. The slot is located on both sides
of the fuselage. Carefully remove the covering. Make sure
you do not cut into the wood.
Step 4: Attach a piece of string to measure the distance
“A” of each stabilizer halves, and “B” the difference
between the wing tip and the top of stabilizer. Both
distances should be equal.
Step 2: Locate the slot for the vertical fin on the top of
the fuselage and remove the covering. Make sure you do
not cut into the wood.
Step 5: With the stabilizer properly aligned, use a felt-tip
pen to trace a line around the tail of the airplane on the
top and bottom of the horizontal stabilizer.
Step 3: Insert the stabilizer into the stabilizer slot so it is
centered in the fuselage (dimension A should be equal).
Place the wing onto the fuselage and secure it in place
with the wing hold-down bolts. View the plane from the
rear and at a distance of a few feet. The stabilizer should
be parallel to the wing (dimension B should be equal). If
not, sand the stabilizer mounting base slightly to achieve
the proper position of the stabilizer.
11
Install the Vertical Fin
Step 6: Remove the stabilizer and draw two additional
lines, top and bottom, 1.6mm inside the lines drawn in
the previous step. Using a knife, carefully cut through the
covering along the inside lines and remove the covering
from the center. Do not cut the wood under the covering!
If the covering is not removed from the stabilizer, a
proper bond for your adhesive will not be achieved.
Step 1: Test fit the vertical fin in the slot in the top of the
fuselage. Sand the edges of the slot if necessary to obtain
a snug fit. Draw a line around the vertical fin where it
meets the fuselage. Cut the covering 1/16” [1.6mm]
inside the lines you drew on the vertical fin and the top of
the fuselage. Remove the covering.
Step 7: Mix 30-minute epoxy and spread some inside the
horizontal stabilizer mount on the fuselage. Spread more
epoxy onto the top and bottom of the stabilizer where the
covering was removed. Insert the stabilizer into the
fuselage from the rear and adjust the alignment using the
guide lines that were drawn onto the stabilizer. Wipe off
any epoxy that squeezes out using a paper towel
dampened with rubbing alcohol. Recheck the alignment
frequently while the epoxy cures.
Step 2: Mix some 30-minute epoxy and apply it to the top
of the horizontal stabilizer through the slot and on the
sides of the slot. Apply more epoxy to the vertical fin
where the covering was removed. Insert the vertical fin
into the fuselage and adjust the alignment. Check for a 90
degree angle between the vertical fin and horizontal
stabilizer when viewed from the rear. Use masking tape to
hold the vertical fin in this position. Recheck the
alignment frequently while the epoxy cures.
12
Install the Elevator
Step 1: Find the pre-cut hinges from the included
accessories. Test fit the hinges in the slots in the elevator
halves and stabilizer. If the hinges do not slide into the
slots easily, work your knife blade back and forth in the
slot a few times to provide more clearance
DRIL L A 3/32 H OL E
DEEP IN CEN TER
OF HINGE SLOT
Step 2: Drill a 3/32” [2.4mm] hole, 1/2” [12.7mm] deep in
the center of the hinge slots. Use a rotary tool with a
3/32” [2.4mm] drill bit or a carbide cutter for the best
results. Reinsert your knife blade to clean out the slot
after you drill the holes.
Step 4: Temporarily insert a pushrod into the elevator
pushrod exit slot. Use the position of the pushrod to align
the elevator control horns onto the undersides of the
elevator halves. Mark the locations of the control horn
mounting holes onto the elevator halves and drill holes at
the marks. Do not drill all the way through the elevator
halves! Thread a screw into the hole and back it out. Apply
a couple drops of thin CA glue to the hole and let it harden.
Attach the elevator control horns to the elevators using
four screws.
Step 3: Insert four hinges into the slots in the stabilizer.
Press the elevators onto the hinges until the gap between
the elevators and stabilizer is about 1/32” [.8mm]. Flex
the elevators a little in one direction, but do not allow
them to pull away from the stabilizer. Apply six drops of
thin CA onto each hinge. Turn the fuselage over and apply
six more drops of thin CA to the other side of each hinge.
DO NOT use accelerator while hinging, as the CA must
wick into the hinge to properly attach the hinges. Use a
paper towel to absorb any excess CA. After the CA cures,
flex the elevators in both directions to free up the
elevators for operation.
13
Install the Rudder and Tail Wheel
Step 3: As you did with the elevator, use the pushrod to
temporarily position a control horn onto the side of the
rudder. Then secure the control horn using two screws.
Step 1: Assemble the tail wheel assembly set using the
included accessories.
Step 2: The installation tab of the tail wheel need to be
mounted on the bottom of the fuselage. Test fit the
rudder to the fuselage with the tail wheel assembly
installed in the orientation shown. Make any adjustments
necessary so the tab on the tail wheel is securely fastened
on the fuse. Roughen the wire on the tail wheel assembly
that fits into the rudder with sand paper and clean it off
with alcohol. Glue the tail wheel wire into the hole in the
LE of the rudder with medium or thick CA glue. Fit the
rudder to the fuselage along with CA hinges. Glue the CA
hinges in place with thin CA glue.
14
Install the Tail Servos and Pushrods
Step 3: Center the rudder, and tighten the set screw to
connect the pushrod to the servo arm.
Step 1: Install the elevator and rudder servos into the
fuselage as shown using the hardware supplied with the
servos. Be sure to harden the screw holes with thin CA as
was done with the aileron servos. Cut three arms from
two four armed servo arms. Center the servos with your
radio system and install them onto the servos with the
servo screws. Enlarge the outer holes of each servo arm
with a 5/64" [2mm] drill bit. Depending on your balancing
needs, you can install the receiver battery in the front of
the fuselage or at the back of the fuselage.
Step 4: Thread the clevis securely onto the elevator
pushrod. We recommend using a clevis retainer to help
keep the clevis in place. Slide the pushrod through the
elevator pushrod exit slot in the fuselage and connect it to
the elevator control horn.
Step 2: Thread the clevis securely onto the rudder
pushrod. We recommend using a clevis retainer to help
keep the clevis in place. Slide the pushrod through the
rudder pushrod exit slot in the fuselage and connect it to
the rudder control horn.
Step5: Center the elevator, and tighten the set screw to
connect the pushrod to the servo arm.
15
Install the Main Landing Gear
Step 4: Mount the main wheels to the axles with the
wheel collars
Step 1: Locate the four blind nuts in the bottom of the
fuse. Cut the covering from the inside of the holes.
Step 2: Mount the aluminum landing gear to the fuse.
Step 3: Mount the two wheel axles.
16
Install Electric Motor
Step4. Install the electric motor to the motor mount using
4 M4*16mm (0.6 in) socket head screws, 4 M4 lock nuts
and 4 M4 washers.
Step1. The tweety-40 does some upgrades on the electric
motor mount. You don’t need to assemble a mount like in
the tweety-25.
Step5. Install the prop and spinner.
Step2. Install the motor mount to the firewall using 3
M4*16mm (0.6 in) socket head screws.
Step3. Prepare an assembled motor as shown.
17
but not touch. The clunks must be able to move freely
inside the tank when assembled. Adjust the length of the
fuel tubing accordingly. When satisfied, tighten the
PM3x25mm screw in the stopper to secure it in place (do
not over-tighten). Mark the side of the tank that must face
up when installed in the plane. We also suggest marking
the tubes in the stopper.
Installing the Fuel Tank (only if you use
nitro motor)
12 m m
Step 1: The fuel tank can be assembled as a two line
system consisting of a vent (pressure) line to the muffler
and a carb line. Filling and emptying of the tank would
need to be done through the carb line, or an optional fuel
fill valve. The tank can also be assembled as a three line
system having a vent line, carb line, and fill line. If
installing a fill line, puncture the top of the stopper above
the sealed off fuel tube hole. The fill and carb lines should
extend out 13mm beyond the stopper and the vent line
should be bent upwards and left uncut. With the tubes
installed in the stopper, the stopper plates loosely in place
with the PM3x25mm screw to hold the assembly together.
Step 3: Insert the tank into the fuselage with the correct
side facing up. The fuel tubing should be routed through
the hole in the center of the firewall.
To p o f t an k
Ven t
F ill an d carb lin es
Step 2: Fit the stopper assembly into the tank with the
vent line pointing toward the top of the tank, but not
touching. The fuel tubing and clunks (fuel pickup) on the
carb and fill lines should almost reach the back of the tank
18
Balancing the Model
Setting Control Throws
After you have finished building the model into ready-tofly condition you can set the C.G. of the model. You need
to have all of the systems installed before you begin,
including the nitro engine or electric motor, landing gear,
radio system, and battery pack.
Turn on the transmitter and receiver. Use a ruler to adjust
the throw of the elevator, ailerons and rudder. Adjust the
position of the pushrod at the control horn to achieve the
following measurements when moving the sticks to their
endpoints:
Aileron Low Rate
Up 9mm
Down 9mm
Aileron High Rate
The C.G. is located 85mm (3.3in) back from the leading
edge of the wing at the fuselage.
Up 16mm
Down 16mm
This is where your model should balance for the first
flights. Later you may wish to experiment by shifting the
C.G. forward or back to change the flying characteristics.
Moving the C.G. forward may improve the smoothness
and stability, but the model may then require more speed
for takeoff and make it more difficult to slow for landing.
Moving the C.G. aft makes the model more maneuverable,
but could also cause it to become too difficult to control.
Elevator Low Rate
Up 10mm
Down 10mm
Elevator High Rate
When balancing your model, support the plane upright at
the C.G. position on the bottom of the wing with your
fingers or a commercially available balancing stand. Move
the battery or receiver inside the fuselage as necessary so
the model hangs level or slightly nose down. This is the
correct balance point for your model.
Up 16mm
Down 16mm
Rudder Low Rate
After the first flights, the CG position can be adjusted for
your personal preference.
`
Up 12mm
Down 12mm
Rudder High Rate
Up 20mm
Down 20mm
These are general guidelines for control throws. You can
experiment with higher rates to match your preferred
style of flying.
