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.

3. Strap the battery pack and receiver onto the

wing joiner tube in the fuselage.

Do not permanently secure the receiver and

battery until after balancing the model.

4. Using a 2mm drill bit, drill a hole through the

side of the fuselage, near the receiver, for the
antenna to exit.

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 20mm 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 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.

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.

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
SENTOSA  size  46-55  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.

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.

SAFETY PRECAUTION

• This is not a toy
• Be sure that no other flyers are using your radio

frequency.

• Do not smoke near fuel
• Store fuel in a cool, dry place, away from

children and pets.

• Wear safety glasses.
• The glow plug clip must be securely attached to

the glow plug.

• Do not flip the propeller with your fingers.
• Keep loose clothing and wires away from the propeller.
• Do not start the engine if people are near. Do not

stand in line with the side of the propeller.

• Make engine adjustments from behind the propeller

only. Do not reach around the spinning propeller.

SERVO INSTALLATION

FUEL TANK installation
INSTALLING THE STOPPER ASSEMBLY

1. The stopper has been pre-assembled at the

factory.

2. Using a modeling knife, cut one length of silicon

fuel  line  (the  length  of  silicon  fuel  line  is
calculated  by  how  the  weighted  clunk  should
rest about 8mm away from the rear of the tank
and  move  freely  inside  the  tank).  Connect  one
end  of  the  line  to  the  weighted  clunk  and  the
other  end  to  the  nylon  pick  up  tube  in  the
stopper.

3. Carefully bend the second nylon tube up at a 45

degree angle (using a cigarette lighter). This
tube will be the vent tube to the muffler.

4. Carefully bend the third nylon tube down at a 45

degree angle (using a cigarette lighter). This
tube will be vent tube to the fueling valve.

5. Test fit the stopper assembly into the tank. It

may  be  necessary  to  remove  some  of  the
flashing  around  the  tank  opening  using  a
modeling  knife.  If  flashing  is  present,  make
sure none of it falls into the tank.

6. When satisfied with the alignment of the stopper

assembly tighten the 3mm x 20mm machine
screw until the rubber stopper expands and
seals the tank opening. Do not over tighten the
assembly as this could cause the tank to split.

7. Using a modeling knife, cut 3 lengths of fuel line

150mm long. Connect 2 lines to the 2 vent
tubes and 1 line to the fuel pickup tube in the
stopper.

8. Feed three lines through the fuel tank

compartment and through the pre-drilled hole in
the  firewall.  Pull  the  lines  out  from  behind  the
engine,  while  guiding  the  fuel  tank  into  place.
Push  the  fuel  tank  as  far  forward  as  possible,
the front of the tank should just about touch the
back of the firewall.

Blow through one of the lines to ensure the fuel

lines have not become kinked inside the fuel
tank compartment. Air should flow through
easily.

Do not secure the tank into place permanently

until after balancing the airplane. You may
need to remove the tank to mount the battery in
the fuel tank compartment.

9. Secure the fuel tank using the plate of plywood

and glue it by C.A glue.

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 the elevator halves.

14. Using thick CA glue, secure the pushrod

sleeves to the pushrod sleeve guide.

3. Working from inside the fuselage, slide the

threaded end of the pushrod until it reaches the
exit slot. Carefully reach in with a small screw
driver and guide the pushrod out of the exit
slot.

4. Install the clevis on the elevator pushrod. Make

sure 6mm of thread shows inside the clevis.

5. The control horn should be mounted on the

bottom, left side of the elevator at the leading
edge, in line with the elevator pushrod.

6. Drill two 3mm holes through the elevator using

the control horn as a guide and screw the
control horn in place.

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 85mm

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 85mm 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.

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.

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.

LANDING GEAR INSTALLATION

1. 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.

INSTALLING THE ENGINE

1. 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.

6. 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. See
photo # 15 below.

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

steering  arm  about  300  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.

8. 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.

2. 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.

3. 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.

4. Remove the hatch cover from the bottom front

of  the  fuselage.  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.

5. 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.  See
figure # 4 below.

3. Repeat step # 1 - # 2 to install the control horn

on the opposite aileron.

2. Attach the clevis to the outer hole in the control

horn. Install a silicone tube on the clevis.

3. Locate one nylon servo arm, and using wire

cutters, remove all but one of the arms. Using a
2mm drill bit, enlarge the third hole out from the
center of the arm to accommodate the aileron
pushrod wire.

4. Plug the aileron servo into the receiver and

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.

8. Insert the 90 degree bend down 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 aileron.

INSTALLING THE AILERON LINKAGES

1. Working with the aileron linkage for now, thread

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

INSTALLING the VERTICAL STABILIZER

1. Using a modeling knife, remove the covering on

the top of the fuselage for the vertical stabilizer.

INSTALLING the HORIZONTAL STABILIZER

1. Using a modeling knife, cut away the covering
from the fuselage for the stabilizer and remove it.

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.

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.
