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

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.

FINAL ASSEMBLY

INSTALLING THE SPINNER

Install the spinner back-plate, propeller and

spinner cone. The spinner cone is held in place
using two 3mm x 12mm wood screws.

The propeller should not touch any part of the

spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.

INSTALLING THE RECEIVER AND BATTERY

1. Plug the servo leads and the switch lead into

the  receiver.  You  may  want  to  plug  an  aileron
extension into the receiver to make plugging in
the  aileron  servo  lead  easier  when  you  are
installing  the  wing.  Plug  the  battery  pack  lead
into the switch.

2. Wrap the receiver and battery pack in the

protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.

INSTALLING THE SWITCH

1. The switch should be mounted on the fuselage

side,  opposite  the  muffler,  close  enough  to  the
receiver  so  the  lead  will  reach.  Use  the  face
plate  of  the  switch  cut  out  and  locate  the
mounting holes.

2. Cut out the switch hole using a modeling knife.

Use a 2mm drill bit and drill out the two
mounting holes through the fuselage side.

3. Secure the switch in place using the two

machine screws provided with the radio system.

13. Insert the 90 degree bend up through the hole

in the servo arm. Install one nylon snap keeper
over the wire to secure it to the arm. Install the
servo arm retaining screw and remove the
masking tape from the rudder.

14.Using thick CA glue, secure the pushrod

sleeves to the pushrod sleeve guide.

Instruction Manual

3. Slide the adjustable metal connector / servo

arm assembly over the plain end of the
pushrod wire. Position the throttle stick and the
throttle trim at their lowest positions.

4. Manually push the carburator barrel fully

closed.  Angle  the  arm  back  about  45  degree
from  center  and  attach  the  servo  arm  onto  the
servo.  With  the  carburator  barrel  fully  closed,
tighte  the  set  screw  in  the  adjustable  metal
connector.

5. Remove the excess throttle pushrod wire using

wire cutters and install the servo arm retaining
screw.

After installing the adjustable metal connector

apply a small drop of thin C/A to the bottom
nut. This will prevent the connector from
loosening during flight.

2. Plug the throttle servo into the receiver and turn

on  the  radio  system.  Check  to  ensure  that  the
throttle  servo  output  shaft  is  moving  in  the
correct  direction.  When  the  throttle  stick  is
moved  forward  from  idle  to  full  throttle,  the
throttle barrel should also open and close using
this  motion.  If  not,  reverse  the  direction  of  the
servo, using the transmitter.

INSTALLING THE THROTTLE

1. Install one adjustable metal connector through

the  third  hole  out  from  the  center  of  one  servo
arm, enlarge the hole in the servo arm using a
2mm  drill  bit  to  accommodate  the  servo
connector.  Remove  the  excess  material  from
the arm.

5. Remove the stabilizer. Using the lines you just

drew as a guide, carefully remove the covering
from between them using a modeling knife.

When cutting through the covering to remove it,

cut with only enough pressure to only cut
through the covering it's self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight.

6. When you are sure that everything is aligned

correctly,  mix  up  a  generous  amount  of  30
minute epoxy. Apply a thin layer to the top and
bottom  of  the  stabilizer  mounting  area  and  to
the  stabilizer  mounting  platform  sides  in  the
fuselage.  Slide  the  stabilizer  in  place  and
re-align.

Double

check

all

your

measurements one more time before the epoxy
cures. Remove any excess epoxy using a
paper towel and rubbing alcohol and hold the
stabilizer in place with T-pins or masking tape.

Glue with epoxy

Remove the covering

7. After the epoxy has fully cured, remove the

masking  tape  or  T-pins  used  to  hold  the
stabilizer in place and carefully inspect the glue
joints.  Use  more  epoxy  to  fill  in  any  gaps  that
were  not  filled  previously  and  clean  up  the
excess using a paper towel and rubbing alcohol.

INSTALLING the VERTICAL STABILIZER

1. Using a modeling knife, remove the covering on

the top of the fuselage for the vertical stabilizer.

2. Slide the vertical stabilizer into the slot in the

mounting platform in the top of the fuselage.
Mark the shape of the fuselage on the left and
right sides of the vertical stabilizer using a
felt-tip pen.

3. Now, remove the vertical stabilizer and using a

modeling  knife,  carefully  cut  just  inside  the
marked lines and remove the film on both sides
of the vertical stabilizer. Just as you did with the
horizontal  stabilizer,  make  sure  you  only  press
hard  enough  to  cut  the  film,  not  the  balsa
vertical stabilizer.

4. Slide the vertical stabilizer back in place. Using

a triangle, check to ensure that the vertical
stabilizer is aligned 90 degree to the horizontal
stabilizer.

5. When you are sure that everything is a aligned

correctly, mix up a generous amount of 30
minute epoxy. Apply a thin layer to the slot in

the mounting platform and to the vertical

stabilizer  mounting  area.  Apply  epoxy  to  the
lower  rudder  hinge.  Set  the  stabilizer  in  place
and  re-align.  Double  check  all  of  your
measurements  once  more  before  the  epoxy
cures.  Remove  any  excess  epoxy  using  a
paper  towel  and  rubbing  alcohol  and  hold  the
stabilizer  in  place  with T-pins  or  masking  tape.
Allow the epoxy to fully cure before proceeding.

Glue with epoxy

2. There are two hardwood landing gear blocks

with  one  precut  channel  in  each  block  in  the
bottom of the wing. Locate the two landing gear
blocks  on  the  bottom  of  the  wing  and  using  a
modeling  knife,  remove  the  covering  from  over
the precut channels. See photo #13 below.

Remove the covering

INSTALLING the LANDING GEAR

1. Locate the two main landing gear wires, one

nose  gear  wire,  four  nylon  mounting  straps
eight  3*12mm  Phillips  head  sheet  metal
screws,  three  wheels,  six  wheel  collars  w/set
screws,  and  one  nylon  steering  arm  with  set
screw. See photo #12 below.

3. Test fit the two main gear wires into the

channels.  When  satisfied  with  the  fit,  secure
the  wires  in  place  using  the  four  nylon  straps
and  eight  3*12mm  sheet  metal  screws.  If  you
look  closely  at  the  wing  surface  surrounding
the  channel  for  the  wire,  you  will  notice  that
there  are  already  four  pilot  holes  drilled  to
accommodate the screws for the straps. Mount
the  straps  at  these  locations.  See  photo  #  14
below.

4. Install two of the wheels onto the axles using

the four wheel collars and set screws provided.
The  wheels  should  be  centered  on  the  axles
with a wheel collar on each side, holding them
in  place. Tighten  the  set  screws  on  the  collars
to  secure  them  in  place.The  wheels  should
rotate  freely. You  should  apply  a  small  drop  of
lock-Tite  thread  lock  to  each  set  screw  to
prevent them from coming loose.

5. Working with the preinstalled nylon steering

housing, position it so the end of it is flush with
the front of the firewall. When satisfied with the
fit, glue the housing to the firewall from the
inside of the fuselage using 5 Minute Epoxy.

one nylon clevis at least 14 turns onto one of
the 2mm x 180mm threaded wires.

INSTALLING THE CONTROL HORNS

1. One aileron control horn in positioned on each

aileron.  Using  a  ruler  and  a  pen,  locate  and
mark  the  location  of  the  control  horn.  It  should
be mounted on the bottom side of the aileron at
the  leading  edge,  in  line  with  the  aileron
pushrod.

2. Drill two 1.6mm holes through the aileron using

the control horn as a guide and screw the

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

65-70mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE.

2. Mount the wing to the fuselage. Using a couple

of pieces of masking tape, place them on the
top side of the wing 65-70mm 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 heavy

nose.  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.

1. 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.

2. 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.

65-70mm

FLIGHT PREPARATION PRE FLIGHT CHECK

1. Completely charge your transmitter and receiver

batteries before your first day of flying.

2. Check every bolt and every glue joint in your

plane to ensure that everything is tight and well
bonded.

3. Double check the balance of the airplane

4. Check the control surface

5. Check the receiver antenna . It should be fully

extended and not coiled up inside the fuselage.

6. Properly balance the propeller.

Elevator Control

Aileron Control

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.

4) Insert the dihedral brace into one wing half up
to the centerline. Wipe off any excess epoxy that
may have squeezed out of the joint using paper
towels.

3)  When  satisfied  with  the  fit  of  the  dihedral
brace  in  each  wing  half,  remove  the  brace  .Mix
equal  amounts  of  part A  and  part  B  30  minute
epoxy.  Coat  all  sides  of  the  dihedral  brace  box
and half of the wing brace with the epoxy. Make
sure to cover the top and bottom as well as the
sides. Use enough epoxy to fill any gaps.

2) Test fit the dihedral brace into each wing half.
The brace should slide in easily up to the
centerline you drew. If it does not, use 220 grit
sandpaper with a sanding block and sand down
the edges and ends of the brace until the proper
fit is obtained.

Center line

5)  Once  the  epoxy  has  cured,  trial  fit  both  wing
halves  together.The  center  gribs  should  fit  flush
together with little or no gaps existing. If gaps do
exist,  use  220  Grit  sandpaper  and  sand  down
the  high  spots  on  the  root  ribs  and  the  wing
joiner until the proper fit is obtainer.

6) To protect the covering from the epoxy used
to glue the wing halves together, carefully apply
masking tape around the edge of the root rip on
the top and bottom of each wing half.

Wing Assembly

Note

* We highly recommend using 30 Minute

Epoxy  over  faster  curing  epoxies  for  several
reasons.  First,  slower  curing  epoxy  is  stronger.  It
also  providers  more  working  time,  allowing  the
builder  to  properly  align  the  parts.  Using  fast  cure
epoxy when joining the wing halves could result in
the glue drying before the wing halves are aligned
properly,  causing  damage  to  the  wing  assembly.
Also, when joining the wing halves, the entire area
of  both  center  ribs  need  to  be  joined  completely
with  no  gaps  existing.  Not  following  these  steps
carefully,  may  result  in  failure  of  the  wing  center
section during flight.

1) Locate the wing dihedral brace. Using a ruler,
locate it's center and place a mark. Draw a
vertical line at the mark just made .

6. The preinstalled wire steering pushrod has a

factory  made  Z-Bend  on  the  front  end  of  it.
Connect  the  nylon  steering  arm  to  this
pushrod.  The  pushrod  should  be  installed  in
the outermost hole in the steering arm.

INSTALLING THE ENGINE

1. Install the engine mount to the fuselage.

2. Locate the long piece of wire used for the throttle

pushrod.  One  end  of  the  wire  has  been
pre-bend in to a "Z" bend at the factory. This "Z"
bend should be inserted into the throttle arm of
the engine when the engine is fitted onto     the
engine  mount.  Fit  the  engine  to  the  engine
mount using the screws provided.

7. Locate the nose gear wire. Slide the nose gear

wire up through the lower portion of the nose
gear block, then through the nylon steering arm,
then through the upper portion of the nose gear
block. The top of the nose gear wire should be
flush with the top of the nose gear bracket.

8. With the nose gear wire straight, angle the nylon

steering arm about 30

forward of the fire-wall

and tighten the set screw. Angling the arm
forward like this will allow room for the arm to
move back for more adequate steering.

9. Install the remaining wheel onto the axle using

the  two  wheel  collars  and  set  screws  provided.
The wheel should be centered on the axle with
a wheel collar on each side, holding it in place.
Tighten  the  set  screws  on  the  collars  to  secure
them  in  place.  The  wheel  should  rotate  freely.
You  should  apply  a  small  drop  of  Lock_tite
thread  lock  to  each  set  screw  to  prevent  them
from coming loose.

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:

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
SONIC LOW WING MK2 GP/EP.25-.32  ARF SCALE
