SUGGESTION
To avoid scratching your new airplane, do not unwrap
the pieces until they are needed for assembly. Cover
your workbench with an old towel or brown paper,
both to protect the aircraft and to protect the table.
Keep a couple of jars or bowls handy to hold the
small parts after you open the bag.
NOTE:
1. Please trial fit all the parts. Make sure you have
the correct parts and that they fit and are aligned
properly before gluing! This will assure proper
assembly. The THUNDER STREAK EDF 120MM
SCALE 1:6 ARF is hand made from natural
materials, every plane is unique and minor
adjustments may have to be made. However, you
should find the fit superior and assembly simple.
2. The painted and plastic parts used in this kit are
fuel proof. However, they are not tolerant of many
harsh chemicals including the following: paint
thinner, C/A glue accelerator, C/A glue debonder
and acetone. Do not let these chemicals come in
contact with the colors on the covering and the
plastic parts.

• Wire cutters
• Masking tape
• Thread lock

• Rubbing alcohol
PREPARATIONS
Remove the tape and separate the ailerons
from the wing and the elevators from the stab.
Use a covering iron with a covering sock on
high heat to tighten the covering if necessary.
Apply pressure over sheeted areas to
thoroughly bond the covering to the wood.
INSTALLING THE AILERONS
1. Test fit the ailerons to the wing with the hinges.
If the hinges don’t remain centered, stick a pin
through the middle of the hinge to hold it in
position.

2. Apply six drops of thin CA to the top and bottom
of each hinge. Do not use CA accelerator. After
the CA has fully hardened, test the hinges by
pulling on the aileron.

center the servo. Install the servo arm onto the
servo. The servo arm should be perpendicular
to the servo and point toward the middle of the
wing.
5. Center the aileron and hold it in place using a
couple of pieces of masking tape.
6. With the aileron and aileron servo centered,
carefully place a mark on the aileron pushrod
wire where it crosses the hole in the servo arm.
7. Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess
wire, leaving about 4mm beyond the bend.

BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
95mm BACK FROM THE LEADING EDGE OF
THE WING, AT THE FUSELAGE. BALANCE A
PLANE UPSIDE DOWN WITH THE FUEL
TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 95mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your
fingers on the masking tape and carefully lift
the plane.
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery
pack further back in the fuselage. If this is not
possible or does not correct it, stick small
amounts of lead weight on the fuselage under
the horizontal stabilizer. If the tail of the plane
falls, the plane is tail heavy. To correct this,
move the battery and receiver forward or if this
is not possible, stick weight into the firewall.
When balanced correctly, the airplane should
sit level or slightly nose down when you lift it up
with your fingers.

LATERAL BALANCE
After you have balanced a plane on the C.G.
You should laterally balance it. Doing this will
help the airplane track straighter.
5. Turn the airplane upside down. Attach one loop
of heavy string to the engine crankshaft and
one to the tail wheel wire. With the wings level,
carefully lift the airplane by the string. This may
require two people to make it easier.
6. If one side of the wing fall, that side is heavier
than the opposite. Add small amounts of lead
weight to the bottom side of the lighter wing
half's wing tip. Follow this procedure until the
wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using
the control throws listed.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.
Ailerons : 7mm up 7mm down
Elevator : 11mm up 11mm down
Rudder : 10mm right 10mm left
Flap T/O: 15mm - Landing 20mm
LOW RATE
95mm
When ready to fly, first extend the
transmitter aerial.
Switch on the transmitter.
Switch on the receiver.
Check that the wings are correctly
fitted to the fuselage.
I/C FLIGHT WARNINGS
Always operate in open areas, away
from factories, hospitals, schools,
buildings and houses etc. NEVER fly
your aircraft close to people or built
up areas.
THE PROPELLER IS DANGEROUS
Keep fingers, clothing (ties, shirt
sleeves, scarves) or any other loose
objects that could be caught or drawn
in, away from the propeller. Take care
at ALL times.
Keep all onlookers (especially small
children and animals) well back from
the area of operation. This is a flying
aircraft, which will cause serious
injury in case of impact with a person
or animal.
NEVER fly near power lines, aerials
or other dangerous areas including
airports, motorways etc.
NEVER use damaged or deformed
propellers or spinners.
DO NOT dispose of empty fuel
containers on a fire, this can lead to
an explosion.
NEVER fly in wet conditions or on
windy or stormy days.
ALWAYS adjust the engine from
behind the propeller, and do not allow
any part of your body to be in line
with the propeller.
I/C FLIGHT GUIDELINES
Made in Vietnam
When ready to fly, first extend the
transmitter aerial.
Operate the control sticks on the
transmitter and check that the control
surfaces move freely and in the
CORRECT directions.
ALWAYS land the model INTO the
wind, this ensures that the model lands
at the slowest possible speed.
Switch on the transmitter.
Switch off the transmitter.
Check that the transmitter batteries
have adequate power.
Switch off the receiver.
Switch on the receiver.
ALWAYS take off into the wind.
Check that the wings are correctly
fitted to the fuselage.
If the model does not respond correctly
to the controls, land it as soon as
possible and correct the fault.
Empty the fuel tank after flying, fuel left
in the tank can cause corrosion and
lead to engine problems.
