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.
Required Items
CA Glue – Thin and Thick
Epoxy glue

Optional – Heat gun
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

Step4. Place the tail boom on the horizontal tail and
adjust tail boom to make the distance of AB is 400mm
(15.7in).
Section 1: Horizontal Tail Installation
Step1. Locate the horizontal tail wing.(The
measurement shows the location of the mounting
block).
Step5. Apply some epoxy to glue the tail boom to the
mounting block. (Adjust the horizontal tail to make it
parallel to the wing).
Step2. Remove the covering for the tail boom
mounting block on the horizontal stabilizer.
Step6. Use a clamp to hold the tail boom and block
until the epoxy cures. (Clamp sold separately.)
Step3. Mix some epoxy, and glue the mounting block
onto the stabilizer.

Step4. Use the CA to glue the vertical tail to the tail
boom. (Adjust to make the vertical tail perpendicular
to the wing).
Section 2: Vertical Tail Installation
Step1. Mark on the vertical fin where 70mm (2.8in)
from the left edge of the vertical tail is.
Note: As shown, when finishing the installation. A=A1,
B=B1, C=C1
Step2. Insert the vertical tail into the tail boom and
adjust the vertical tail to make the left edge of tail
boom is aligned with the marked line.
Use a felt-tipped pen to trace the outline of the tail
boom onto the vertical stabilizer.
Step3. Cut and trim the coverings inside the lines
drawn in the pervious step, and remove it.

Step4. Thread the pushrod wire into the clevis and
tighten the bolt.
Connect the clevis to the control horn.
Position the control horn on the rudder, the pushrod
wire will be aligned with the tail boom, and drill the
mounting holes for the bolts.
Section 3: Elevator and Rudder Servo
and Linkage Installation
Step1. Install two servos on the servo mounts.
Step2. Thread the 790mm (31.1in) pushrod wire into
the tail boom. The z-bend will be towards the tail.
Step5. Use three M2*10mm (.4in) bolts to secure the
control horn to the rudder.
Step3. Install the servo arm with pushrod connector
in the servo. Center the servo arm electronically and
slide the pushrod wire into the connector.
Step6. Center the control surface and tighten the
screw on the pushrod connector.

Step7. Finish the elevator servo and linkage
installation in the same way.
Step3. Use two M2*8mm (.3in) self-tapping screws to
secure the two blocks wont loose. (Center the servo
arm before mounting.)
Step4. Use two M2*8mm (.3in)self-tapping screws to
mount the servo to the blocks.
Step5. Remove the coverings on the wing for the
servo wires as shown.
Section 4: Aileron Servo and Linkage
Installation.
Step1. Locate the items shown in the picture.
Step6. Thread the servo wire through the wing.
Step2. Glue two servo mounting blocks to the hatch
inside the markings.

www.valuehobby.com/apollo-dlg.html
Step7. Thread the clevis onto the aileron pushrod and
connect the clevis to the servo arm.
Mount the servo hatch to the wing using four
M2*8mm (.3in) self-tapping screws.
Section 5: Wing Installation
Step1. Locate the items shown in the picture.
Step2. Insert the two wing tubes
{10mm(.4in)*128mm(5.0in) and Ф80mm(3.1in)}into
the wing panel, and slide the other panel onto wing
tube.
Step8. Use glue and two hinges to attach the aileron
to the wing.
Step9. With the pushrod wire 90-degrees to the hinge
line, connect the pushrod wire to the servo control
horn using a pushrod connector.
Step3. Attach the wing onto the fuselage using two
bolts plate and four M3 Allen bolts. Tighten the bolts
using a screwdriver. {Two M3*30mm (1.2in) bolts are
for the front plate, and two M3*25mm (1.0in) bolts
for the other one}.
Step10. Repeat the pervious steps to finish the other
aileron servo installation.

Section 6: Battery Installation
Section 9: Adjust the CG.
Install the battery into the fuselage as shown. Sponge
can be used to prevent the battery from moving.
For the first flights, the recommended Center of
Gravity location is 260mm (10.2in) behind the nose.
Use the battery pack, moving it forward or backward,
to achieve the correct balance.
Section 7: Canopy Installation
Section 10: Set the Control Throws
Use a M2*8mm (.3in) self-tapping screw to secure
the canopy onto the fuselage.
Use a ruler to accurately measure and set the control
throw of each control surface as indicated in the chart.
If your radio does not have dual rates, we recommend
setting the throws at the high rate.

Section 8: Throwing Peg Installation
If you are right handed, remove the covering from the
hole in the left wing tip. If you are left handed,
remove the covering from the hole in the right wing
tip.
Push the carbon throwing peg into the hole in the
wing tip. Apply a small amount of epoxy to the peg
and twist the peg so that the epoxy goes into the
wing and the peg is centered vertically in the wing.

Section 11: Method of Throwing
Step1. Your right index finger and middle finger
should be wrapped around the peg.
Step4. This is the second half of the rotation and the
section that is most responsible for a good high lunch.
Do not use too much arm in this section. Just let the
rotation of your torso speed the plane up.
Step2. Stand with your left shoulder into the wind
and the right wing tip on the ground.
Step5. By this time in the launch, the plane will be
trying to climb on its own. Just release your fingers
and let the plane fly out of your hand. Try to release it
directly into the wind.
Step3. Start rotating to the left keeping the plane flat
and your arm extended.
Step6. This last step is just to catch your balance and
watch your plane climb for the clouds.
