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 at your location, 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.

Aileron Installation
Step 1
Check to make sure you have the correct
aileron. The trim will match the bottom of the
wing.
Step 2
Use a pin vise and 1/16-inch (1.5mm) drill bit to
drill a hole in the center of each hinge slot. Drill
holes for both the aileron and wing.
5
Step 3
Place a T-pin in the center of each hinge.
Insert the hinges in the slots in the trailing edge
of the wing. Try to align the slot in the hinge
with the hole drilled in the previous step.
Step 4
Use the hinges to place the aileron in position.
Use a hobby knife to set the gap between the
control surface and the wing. Also check that the
aileron can move freely without rubbing the wing
tip.
Step 5
Saturate each of the hinges with thin CA. Make
sure to glue both the top and bottom. Once the
CA has cured, gently pull on the aileron to make
sure the hinges are secure. If not, apply more CA
to the loose hinge.
6
Step 6
Flex the aileron up and down a number of
times to break in the aileron hinges.
Aileron Servo Installation
Required Parts
Step 1
Use string to secure a 9-inch (230mm) servo
extension to the aileron servo
7
Step 2
Use a hobby knife and #11 blade to remove
the covering for the outboard servo in the
bottom of the wing. Tie a weight (wheel collar
or nut) to a 12-inch (300mm) piece of string
and lower it into the opening for the servo. Tip
the wing up so the weight can be retrieved at
the center of the wing as shown.
Step 3
Tie the string around the servo lead. Pull the
lead through the wing and out of the hole at the
center.
Step 4
Position the servo in the wing with the servo
output shaft toward the aileron (or flap). Use a
felt-tipped pen to mark the locations for the
mounting screws. Use a pin vise and 1/16inch (1.5mm) drill bit to drill the holes for the
screws. Use 2 - 3 drops of thin CA to harden the
surrounding wood.
Step 5
Secure the servo in the wing using a #1
Phillips screwdriver and the hardware provided
with the servo.
Step 6
Slide a clevis retainer on a clevis, then thread
the clevis 12-turns on a 4-inch (100mm)
pushrod wire. Connect the clevis to the control
horn as shown.
8
Step 7
Use a pin vise and 2mm drill bit to enlarge the
hole in the servo horn that is 1/2-inch (13mm)
from the center of the horn. With the pushrod
wire aligned 90-degrees to the hinge line and
the holes in the control horn aligned with the
hinge line, use a felt-tipped pen to mark the
control surface for the control horn screws.
Step 8
Use a pin vise and a 5/64-inch (2mm) drill bit to
drill the two holes for the control horn screws.
Apply 2 3 drops in each hole to harden the
surrounding wood. Secure the control horn
using two 2-56 x 5/8-inch machine screws and a
control horn backplate. Tighten the screws using
a #1 Phillips screwdriver.
9
Step 9
With the control surface centered, use a felttipped pen to mark the pushrod where it
crosses the hole of the servo horn. Use pliers
to bend the pushrod 90-degrees at the mark.
Step 10
Use diagonal cutters to trim the pushrod wire
3/8-inch (9.5mm) above the bend. Secure the
pushrod wire to the servo horn using a pushrod
keeper. Use diagonal cutters to remove any
unused servo arm from the servo horn.
Step 11
Repeat Steps 1 through 10 to install the
remaining servo.
10
Joining the Wing Panels
Step 1
Mark the wing joiner and wing panel using a felttipped pen. This is so you can orient the joiner
correctly in this section of the manual.
Step 2
Mark a center line on the joiner. It should slide
into each wing panel up to the line. If not, lightly
sand the joiner so it fits correctly.
11
Step 3
Use 30-minute epoxy to glue the joiner into the
wing panels. Apply epoxy in the joiner pocket
and all sides of the joiner, including the top and
bottom edges. Also coat the exposed wood on
the root rib with epoxy. Start with one panel,
insert the joiner, then the opposite panel.
Step 4
Make sure the wing panels fit tightly together. Clean
any epoxy using a paper towel and rubbing alcohol.
Use low-tack tape to keep the panels tightly
together while the epoxy cures.
Important: Make sure the leading edge and
trailing edges of the wing at the joint are aligned
with each other.
12
Completing the Wing Assembly
Step 1
Use a hobby knife to remove the covering to
expose the holes in the wing bolt plate. Also
remove the covering from one side of the plate.
Leave a 1/16-inch (1.5mm) edge of covering
around the perimeter as shown in the second
photo.
Step 2
Position the wing bolt plate on the wing, aligning
the holes with those in the wing. Trace the outline
of the plate onto the
wing using a felt-tipped pen. Use a hobby knife
and #11 blade to trim the covering from the wing
1/16-inch (1.5mm) inside the line drawn.
13
Step 3
Use 30-minute epoxy to glue the wing bolt
plate to the wing. Use low-tack tape to keep
the plate secure while the epoxy cures. Use a
covering iron to apply the covering over the
seam between the wing panels.
Horizontal Stabilizer Installation
Required Parts
Step 1
Install the wing by aligning the dowels from the
wing into the holes in the fuselage.
14
Step 2
Secure the wing using two wing bolts. Tighten
the bolts using a screwdriver.
Step 3
Use a ruler to mark the center of the stabilizer.
Do not use the covering as a guide as it may not
be centered. Use a T-pin at the rear of the
stabilizer as a pivot and to keep the stabilizer in
position on the fuselage.
Step 4
Check the alignment of the stabilizer to the wing.
Position the stabilizer so the measurements from
the stabilizer tips to the wing tips are equal. Also
check that the stabilizer is parallel to the wing.
Lightly sand the stabilizer saddle if adjustments
are required.
15
Step 5
Use a felt-tipped pen to trace the outline of the
fuselage on the stabilizer. Use a hobby knife
and #11 blade to remove the covering from the
center of the stabilizer 1/16-inch (1.5mm)
inside the line drawn. Use 30-minute epoxy to
glue the stabilizer to the fuselage. Use a paper
towel and rubbing alcohol to remove any
excess epoxy before it has a chance to fully
cure. Allow the epoxy to cure before
proceeding.
Vertical Fin Installation
Required Parts
Step 1
Insert the fin in the slot at the rear of the
fuselage. Use a felt-tipped pen to trace the
outline of the fuselage on the area of the fin that
fits into the fuselage. Also trace the outline of the
fin on the top of the fuselage.
Step 2
Use a hobby knife and #11 blade to remove
the covering from the fuselage and fin. Trim
the covering 1/16-inch (1.5mm) inside the lines
drawn on the fuselage, and 1/16-inch (1.5mm)
below the line on the fin.
Step 3
Use 30-minute epoxy to glue the fin to the
fuselage. Use a square to check the alignment
of the fin to the stabilizer while the epoxy cures
to make sure it is aligned properly.
16
Preparation for Tail Landing Gear
Installation
Step 1
Mark where it is 15mm from the tip of the rudder
and use 1.8mm drill bit to drill a hole 10mm deep.
Required Parts
17
Step 2
Use a hobby knife and #11 blade to cut a
groove from the hole in the rudder to the
bottom of the rudder for the tail gear wire to fit
into.
Step 3
Bend the rod 90 degrees as shown.
Step 4
Insert the tail gear wire into the rudder. It should
fit as shown. Use 30-minute epoxy to glue the
wire into the fin.
18
Step 5
Fit the rudder to the fin. Use a hobby knife and
#11 blade to check the hinge gap and that the
rudder is not rubbing the top of the fin.
Step 6
Use thin CA to glue the two hinges that secure
the rudder and fin. Perform a pull test on the
hinges and break them in at this time.
Step 7
Position the elevator against the stabilizer. Use a
felt-tipped pen to mark where the tail wheel wire
rests against the elevator. Use a rotary tool and
sanding drum to make a notch so the elevator
does not bind against the landing gear.
19
Step 8
Insert a T-pin in the center of the six stabilizer
hinges. Insert the hinges in the elevator as
shown.
Step 9
Install the elevator against the stabilizer using
the hinges. Set the hinge gap using a hobby
knife and #11 blade. Saturate each hinge using
thin CA. Allow the CA to fully cure before
checking the hinges.
Step 10
Flex the elevator up and down a number of times
to break in the hinges.
20
Step11
Secure the tail landing gear to the horizontal
stabilizer and install the wheel to the landing
gear.
Radio Installation
Required Parts
Step 1
Use the hardware to mount the servos in the
fuselage. Note the servo tube near the rudder
servo. The wire will exit near the rudder as
shown. Use a hobby knife and #11 blade to trim
the covering so the wire can exit the fuselage.
21
Step 2
Slide a clevis retainer on a clevis, then thread
the clevis on the pushrod wire. Connect the
clevis to the control horn as shown. With the
holes in the control horn aligned with the hinge
line, use a felt-tipped pen to mark the mounting
locations for the control horn mounting screws.
Step 3
Use a pin vise and 5/64-inch (2mm) drill bit to
drill the holes for the screws. Use 2- 3 drops of
thin CA to harden the holes. Secure the control
horn to the rudder using two machine screws
and a control horn back-plate.
Step 4
With the rudder servo centered, attach the arm
to the servo. With the rudder centered, use a
felt-tipped pen to mark the pushrod wire where
it crosses the outside hole of the servo horn.
Use pliers to bend the wire 90-degrees at the
mark.
22
Step 5
Trim the wire 3/8-inch (9.5mm) above the bend.
Use a pushrod keeper to secure the pushrod
wire to the rudder servo horn.
Step 6
Repeat Steps 2 through 8 to connect the elevator
pushrod wire. When preparing the servo horn,
use a hole that is 1/2-inch (13mm) from the
center of the servo horn.
23
Landing Gear Installation
Required Parts
Step 1
Secure the axle to the landing gear using pliers
and hex wrench.
24
Step 2
Slide a wheel collar on the axle, and tighten
the wheel collar using a grub screw.
Step 3
Slide the wheel on the axle and use the other
wheel collar to secure the wheel to the axle.
(Need to check if the wheel spins freely after
installation.)
Step 4
Remove the covering for the main landing gear
mount.
25
Step 5
Secure the assembled landing gear to the
fuselage using two M3*12 screw. When
installing the gear, note the angle of the gear.
The angled edge will be to the rear of the
fuselage when installed.
Nitro Engine Installation
Required Parts
Step 1
Attach the engine mount rails to the firewall using
four M3*20socket head screws and four M3
washers. Leave them slightly loose so the mount
rails can be moved to fit your particular engine.
26
Step 2
Secure the engine to the mount rails.(2 stroke
engine is shown as an example)
Step 3
Install the propeller and spinner following the
instructions provided with the engine. Never use
an adjustable wrench to install the propeller nut
as it will eventually round the corners of the nut,
making it difficult to tighten or loosen in the
future.
Step 4
Slide the long and short aluminum tubes into the
stopper. The holes for these tubes are pre-made
in the stopper. Slide the metal disk (small) on the
back of the stopper, while the metal disk (large)
goes on the front of the stopper.
27
Step 5
Use a #1 Phillips screwdriver to start the 3mm
x 20mm machine screw. The screw only needs
to be flush with the metal disk (small) at this
time. Carefully bend the longer aluminum tube
up at a 45-degree angle, being careful not to
place a kink in the tube.
Step 6
Slide the fuel tube on the short aluminum tube.
The clunk will fit on the opposite end of the tube.
Insert the stopper in the tank and make sure the
clunk can move freely inside the tank. If not,
shorten the tube slightly so the clunk does not
bind inside the tank.
Step 7
Once the clunk line has been adjusted, tighten
the 3mm x 20mm machine screw with a #1
Phillips screwdriver to secure the stopper in the
tank. Place the pink fuel tube on the vent line,
and the green fuel tube on the tube that goes to
the clunk.
28
Step 8
Install the throttle pushrod as shown
Step 9
Insert the tank into the fuselage with the correct
side facing up. Secure it with straps.
Step 10
Position the nose cover plate on the fuselage.
29
Step 2. Connect the ESC to the motor and
secure it to the inside of the fuselage using
hook and loop material. Actual ESC location
may vary.
Electronics Installation
Required Parts
Step 1. Place the four 4-40 blind nuts on the
inside of the firewall in the locations for your
particular motor. Attach the Outrunner motor to
the front of the firewall using M3*20" socket
head screws.
Important Information About Your Brushless
ESC. Make sure your ESC brake is programmed
